-### Quick!
+Do note that this is only required if you want to test out your custom changes in a separate site (not the one in the Umbraco.Web.UI), if you just want to test your changes you can run the included test site using: `dotnet run` from `src/Umbraco.Web.UI/`

+You may want to build a set of NuGet packages with your changes, this can be done using the dotnet pack command.

-If you only see a build.bat-file, you're probably on the wrong branch. If you switch to the correct branch (v8/contrib) the file will appear and you can build it.
+`dotnet pack -c Release -o Build.Out`
 
-You might run into [Powershell quirks](#powershell-quirks).
+This will restore and build the project using the release configuration, and put all the outputted files in a folder called `Build.Out`
 
-If it runs without errors; Hooray! Now you can continue with [the next step](CONTRIBUTING.md#how-do-i-begin) and open the solution and build it.
+You can then add these as a local NuGet feed using the following command:
 
+`dotnet nuget add source <Path to Build.Out folder> -n MyLocalFeed`
 
-### Build Infrastructure
-
-The Umbraco Build infrastructure relies on a PowerShell object. The object can be retrieved with:
-
-    $ubuild = build/build.ps1 -get
-
-The object exposes various properties and methods that can be used to fine-grain build Umbraco. Some, but not all, of them are detailed below.
-    
-#### Properties
-
-The object exposes the following properties:
-
-* `SolutionRoot`: the absolute path to the solution root
-* `VisualStudio`: a Visual Studio object (see below)
-* `NuGet`: the absolute path to the NuGet executable
-* `Zip`: the absolute path to the 7Zip executable
-* `VsWhere`: the absolute path to the VsWhere executable
-* `NodePath`: the absolute path to the Node install
-* `NpmPath`: the absolute path to the Npm install
-
-The Visual Studio object is `null` when Visual Studio has not been detected (eg on VSTS). When not null, the object exposes the following properties:
-
-* `Path`: Visual Studio installation path (eg some place under `Program Files`)
-* `Major`: Visual Studio major version (eg `15` for VS 2017)
-* `Minor`: Visual Studio minor version
-* `MsBuild`: the absolute path to the MsBuild executable
-
-#### GetUmbracoVersion
-
-Gets an object representing the current Umbraco version. Example:
-
-    $v = $ubuild.GetUmbracoVersion()
-    Write-Host $v.Semver
-
-The object exposes the following properties:
-
-* `Semver`: the semver object representing the version
-* `Release`: the main part of the version (eg `7.6.33`)
-* `Comment`: the pre release part of the version (eg `alpha02`)
-* `Build`: the build number part of the version (eg `1234`)
-
-#### SetUmbracoVersion
-
-Modifies Umbraco files with the new version.
-
->This entirely replaces the legacy `UmbracoVersion.txt` file. Do *not* edit version infos in files.
-
-The version must be a valid semver version. It can include a *pre release* part (eg `alpha02`) and/or a *build number* (eg `1234`). Examples:
-
-    $ubuild.SetUmbracoVersion("7.6.33")
-    $ubuild.SetUmbracoVersion("7.6.33-alpha.2")
-    $ubuild.SetUmbracoVersion("7.6.33+1234")
-    $ubuild.SetUmbracoVersion("7.6.33-beta.5+5678")
-
-#### Build
-
-Builds Umbraco. Temporary files are generated in `build.tmp` while the actual artifacts (zip files, NuGet packages...) are produced in `build.out`. Example:
-
-    $ubuild.Build()
-
-Some log files, such as MsBuild logs, are produced in `build.tmp` too. The `build` directory should remain clean during a build.
-
-**Note: web.config**
-
-Building Umbraco requires a clean `web.config` file in the `Umbraco.Web.UI` project. If a `web.config` file already exists, the `pre-build` task (see below) will save it as `web.config.temp-build` and replace it with a clean copy of `web.Template.config`. The original file is replaced once it is safe to do so, by the `pre-packages` task.
-
-#### Build-UmbracoDocs
-
-Builds umbraco documentation. Temporary files are generated in `build.tmp` while the actual artifacts (docs...) are produced in `build.out`. Example:
-
-    Build-UmbracoDocs
-
-Some log files, such as MsBuild logs, are produced in `build.tmp` too. The `build` directory should remain clean during a build.
-
-#### Verify-NuGet
-
-Verifies that projects all require the same version of their dependencies, and that NuSpec files require versions that are consistent with projects. Example:
-
-    Verify-NuGet
+This will add a local nuget feed with the name "MyLocalFeed" and you'll now be able to use your custom built NuGet packages. 
 
 ### Cleaning up
 
 Once the solution has been used to run a site, one may want to "reset" the solution in order to run a fresh new site again.
 
-At the very minimum, you want
+The easiest way to do this by deleting the following files and folders:
+* src/Umbraco.Web.UI/appsettings.json
+* src/Umbraco.Web.UI/umbraco/Data
 
-    git clean -Xdf src/Umbraco.Web.UI/App_Data
-    rm src/Umbraco.Web.UI/web.config
+You only have to remove the connection strings from the appsettings, but removing the data folder  ensures that the sqlite database gets deleted too.
 
-Then, a simple 'Rebuild All' in Visual Studio will recreate a fresh `web.config` but should be quite fast (since it does not really need to rebuild anything).
-
-The `clean` Git command force (`-f`) removes (`-X`, note the capital X) all files and directories (`-d`) that are ignored by Git.
+Next time you run a build the `appsettings.json` file will be re-created in its default state.
 
 This will leave media files and views around, but in most cases, it will be enough.

+Umbraco uses Azure DevOps for continuous integration, nightly builds and release builds. The Umbraco CMS project on DevOps [is available for anonymous users](https://umbraco.visualstudio.com/Umbraco%20Cms)..
 
-DevOps uses the `Build-Umbraco` command several times, each time passing a different *target* parameter. The supported targets are:
-
-* `pre-build`: prepares the build
-* `compile-belle`: compiles Belle
-* `compile-umbraco`: compiles Umbraco
-* `pre-tests`: prepares the tests
-* `compile-tests`: compiles the tests
-* `pre-packages`: prepares the packages
-* `pkg-zip`: creates the zip files
-* `pre-nuget`: prepares NuGet packages
-* `pkg-nuget`: creates NuGet packages
-
-All these targets are executed when `Build-Umbraco` is invoked without a parameter (or with the `all` parameter). On VSTS, compilations (of Umbraco and tests) are performed by dedicated DevOps tasks. Similarly, creating the NuGet packages is also performed by dedicated DevOps tasks.
-
-Finally, the produced artifacts are published in two containers that can be downloaded from DevOps: `zips` contains the zip files while `nuget` contains the NuGet packages.
-
->During a DevOps build, some environment `UMBRACO_*` variables are exported by the `pre-build` target and can be reused in other targets *and* in DevOps tasks. The `UMBRACO_TMP` environment variable is used in `Umbraco.Tests` to disable some tests that have issues with DevOps at the moment.
+The produced artifacts are published in a container that can be downloaded from DevOps called "nupkg" which contains all the NuGet packages that got built.
 
 ## Quirks
 
-### PowerShell Quirks
-
-There is a good chance that running `build.ps1` ends up in error, with messages such as
-
->The file ...\build.ps1 is not digitally signed. You cannot run this script on the current system. For more information about running scripts and setting execution policy, see about_Execution_Policies.
-
-PowerShell has *Execution Policies* that may prevent the script from running. You can check the current policies with:
-
-    PS> Get-ExecutionPolicy -List
-    
-            Scope ExecutionPolicy
-            ----- ---------------
-    MachinePolicy       Undefined
-       UserPolicy       Undefined
-          Process       Undefined
-      CurrentUser       Undefined
-     LocalMachine    RemoteSigned
-
-Policies can be `Restricted`, `AllSigned`, `RemoteSigned`, `Unrestricted` and `Bypass`. Scopes can be `MachinePolicy`, `UserPolicy`, `Process`, `CurrentUser`, `LocalMachine`. You need the current policy to be `RemoteSigned`&mdash;as long as it is `Undefined`, the script cannot run. You can change the current user policy with:
-
-    PS> Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned
-
-Alternatively, you can do it at machine level, from within an elevated PowerShell session:
-
-    PS> Set-ExecutionPolicy -Scope LocalMachine -ExecutionPolicy RemoteSigned
-
-And *then* the script should run. It *might* however still complain about executing scripts, with messages such as:
-
->Security warning - Run only scripts that you trust. While scripts from the internet can be useful, this script can potentially harm your computer. If you trust this script, use the Unblock-File cmdlet to allow the script to run without this warning message. Do you want to run ...\build.ps1?
-[D] Do not run  [R] Run once  [S] Suspend  [?] Help (default is "D"):
-
-This is usually caused by the scripts being *blocked*. And that usually happens when the source code has been downloaded as a Zip file. When Windows downloads Zip files, they are marked as *blocked* (technically, they have a Zone.Identifier alternate data stream, with a value of "3" to indicate that they were downloaded from the Internet). And when such a Zip file is un-zipped, each and every single file is also marked as blocked.
-
-The best solution is to unblock the Zip file before un-zipping: right-click the files, open *Properties*, and there should be a *Unblock* checkbox at the bottom of the dialog. If, however, the Zip file has already been un-zipped, it is possible to recursively unblock all files from PowerShell with:
-
-    PS> Get-ChildItem -Recurse *.* | Unblock-File
-
 ### Git Quirks
 
 Git might have issues dealing with long file paths during build. You may want/need to enable `core.longpaths` support (see [this page](https://github.com/msysgit/msysgit/wiki/Git-cannot-create-a-file-or-directory-with-a-long-path) for details).

-## Before you start
-
-
-### Code of Conduct
-
-This project and everyone participating in it, is governed by the [our Code of Conduct][code of conduct].
-
-### What can I contribute?
-
-We categorise pull requests (PRs) into two categories:
-
-| PR type   | Definition                                                   |
-| --------- | ------------------------------------------------------------ |
-| Small PRs | Bug fixes and small improvements - can be recognized by seeing a small number of changes and possibly a small number of new files. |
-| Large PRs | New features and large refactorings - can be recognized by seeing a large number of changes, plenty of new files, updates to package manager files (NuGet’s packages.config, NPM’s packages.json, etc.). |
-
-We’re usually able to handle small PRs pretty quickly. A community volunteer will do the initial review and flag it for Umbraco HQ as “community tested”. If everything looks good, it will be merged pretty quickly [as per the described process][review process].
-
-We would love to follow the same process for larger PRs but this is not always possible due to time limitations and priorities that need to be aligned. We don’t want to put up any barriers, but this document should set the correct expectations. 
-
-Not all changes are wanted, so on occasion we might close a PR without merging it but if we do, we will give you feedback why we can't accept your changes. **So make sure to [talk to us before making large changes][making larger changes]**, so we can ensure that you don't put all your hard work into something we would not be able to merge.
-
-#### Making larger changes
-
-[making larger changes]: #making-larger-changes
-
-Please make sure to describe your larger ideas in an [issue (bugs)][issues] or [discussion (new features)][discussions], it helps to put in mock up screenshots or videos. If the change makes sense for HQ to include in Umbraco CMS we will leave you some feedback on how we’d like to see it being implemented. 
-
-If a larger pull request is encouraged by Umbraco HQ, the process will be similar to what is described in the small PRs process above, we strive to feedback within 14 days. Finalizing and merging the PR might take longer though as it will likely need to be picked up by the development team to make sure everything is in order. We’ll keep you posted on the progress.
-
-#### Pull request or package?
-
-[pr or package]: #pull-request-or-package
-
-If you're unsure about whether your changes belong in the core Umbraco CMS or if you should turn your idea into a package instead, make sure to [talk to us][making larger changes].
-
-If it doesn’t fit in CMS right now, we will likely encourage you to make it into a package instead. A package is a great way to check out popularity of a feature, learn how people use it, validate good usability and fix bugs. Eventually, a package could "graduate" to be included in the CMS.
-
-#### Ownership and copyright
-
-It is your responsibility to make sure that you're allowed to share the code you're providing us. For example, you should have permission from your employer or customer to share code.
-
-Similarly, if your contribution is copied or adapted from somewhere else, make sure that the license allows you to reuse that for a contribution to Umbraco-CMS.
-
-If you're not sure, leave a note on your contribution and we will be happy to guide you.
-
-When your contribution has been accepted, it will be [MIT licensed][MIT license] from that time onwards.
-
-## Finding your first issue: Up for grabs
-
-Umbraco HQ will regularly mark newly created issues on the issue tracker with [the `community/up-for-grabs` tag][up for grabs issues]. This means that the proposed changes are wanted in Umbraco but the HQ does not have the time to make them at this time. We encourage anyone to pick them up and help out.
-
-If you do start working on something, make sure to leave a small comment on the issue saying something like: "I'm working on this". That way other people stumbling upon the issue know they don't need to pick it up, someone already has.
-

+8. **Create pull request**
 
-Once you've already got a fork and cloned your fork locally, you can skip steps 1 and 2 going forward. Just remember to keep your fork up to date before making further changes.
+    On GitHub, in your forked repository (`https://github.com/[YourUsername]/Umbraco-CMS`) you will see a banner saying that you pushed a new branch and a button to make a pull request. Tap the button and follow the instuctions.
 
-To sync your fork with this original one, you'll have to add the upstream url. You only have to do this once:

-Then when you want to get the changes from the main repository:

+- [Unwanted changes](contributing-unwanted-changes.md)
+- [Other ways to contribute](contributing-other-ways-to-contribute.md)
 
-```
-git fetch upstream
-git rebase upstream/v10/contrib
-```
-
-In this command we're syncing with the `v10/contrib` branch, but you can of course choose another one if needed.
-
-[More information on how this works can be found on the thoughtbot blog.][sync fork ext]
-
-#### Style guide
-
-To be honest, we don't like rules very much. We trust you have the best of intentions and we encourage you to create working code. If it doesn't look perfect then we'll happily help clean it up.
-
-That said, the Umbraco development team likes to follow the hints that ReSharper gives us (no problem if you don't have this installed) and we've added a `.editorconfig` file so that Visual Studio knows what to do with whitespace, line endings, etc.
-
-#### Questions?
-[questions]: #questions
-
-You can get in touch with [the core contributors team][core collabs] in multiple ways; we love open conversations and we are a friendly bunch. No question you have is stupid. Any question you have usually helps out multiple people with the same question. Ask away:
-
-- If there's an existing issue on the issue tracker then that's a good place to leave questions and discuss how to start or move forward.
-- If you want to ask questions on some code you've already written you can create a draft pull request, [detailed in a GitHub blog post][draft prs].
-- Unsure where to start? Did something not work as expected? Try leaving a note in the ["Contributing to Umbraco"][contrib forum] forum. The team monitors that one closely, so one of us will be on hand and ready to point you in the right direction.
-
-## Creating a pull request
-
-Exciting! You're ready to show us your changes.
-
-We recommend you to [sync with our repository][sync fork] before you submit your pull request. That way, you can fix any potential merge conflicts and make our lives a little bit easier.
-
-GitHub will have picked up on the new branch you've pushed and will offer to create a Pull Request. Click that green button and away you go.
-![Create a pull request](img/createpullrequest.png)
-
-We like to use [git flow][git flow] as much as possible, but don't worry if you are not familiar with it. The most important thing you need to know is that when you fork the Umbraco repository, the default branch is set to something, usually `v10/contrib`. If you are working on v9, this is the branch you should be targeting.
-
-Please note: we are no longer accepting features for v8 and below but will continue to merge security fixes as and when they arise.
-
-## The review process
-[review process]: #the-review-process
-
-You've sent us your first contribution - congratulations! Now what?
-
-The [Core Collaborators team][Core collabs] can now start reviewing your proposed changes and give you feedback on them. If it's not perfect, we'll either fix up what we need or we can request that you make some additional changes.
-
-You will get an initial automated reply from our [Friendly Umbraco Robot, Umbrabot][Umbrabot], to acknowledge that we’ve seen your PR and we’ll pick it up as soon as we can. You can take this opportunity to double check everything is in order based off the handy checklist Umbrabot provides.
-
-You will get feedback as soon as the [Core Collaborators team][Core collabs] can after opening the PR. You’ll most likely get feedback within a couple of weeks. Then there are a few possible outcomes:
-
-- Your proposed change is awesome! We merge it in and it will be included in the next minor release of Umbraco
-- If the change is a high priority bug fix, we will cherry-pick it into the next patch release as well so that we can release it as soon as possible
-- Your proposed change is awesome but needs a bit more work, we’ll give you feedback on the changes we’d like to see
-- Your proposed change is awesome but... not something we’re looking to include at this point. We’ll close your PR and the related issue (we’ll be nice about it!). See [making larger changes][making larger changes] and [pull request or package?][pr or package]
-
-### Dealing with requested changes
-
-If you make the corrections we ask for in the same branch and push them to your fork again, the pull request automatically updates with the additional commit(s) so we can review it again. If all is well, we'll merge the code and your commits are forever part of Umbraco!
-
-#### No longer available?
-
-We understand you have other things to do and can't just drop everything to help us out.
-
-So if we’re asking for your help to improve the PR we’ll wait for two weeks to give you a fair chance to make changes. We’ll ask for an update if we don’t hear back from you after that time.  
-
-If we don’t hear back from you for 4 weeks, we’ll close the PR so that it doesn’t just hang around forever. You’re very welcome to re-open it once you have some more time to spend on it.  
-
-There will be times that we really like your proposed changes and we’ll finish the final improvements we’d like to see ourselves. You still get the credits and your commits will live on in the git repository.

-# New backoffice
-
-> **Warning**:
-> This is an early WIP and is set not to be packable since we don't want to release this yet. There will be breaking changes in these projects.
-
-This solution folder contains the projects for the new backoffice. If you're looking to fix or improve the existing CMS, this is not the place to do it, although we do very much appreciate your efforts.
-
-### Project structure
-
-Since the new backoffice API is still very much a work in progress, we've created new projects for the new backoffice API:
-
-* Umbrao.Cms.ManagementApi - The "presentation layer" for the management API
-* "New" versions of existing projects, should be merged with the existing projects when the new API is released:
-    * Umbraco.New.Cms.Core
-    * Umbraco.New.Cms.Infrastructure
-    * Umbraco.New.Cms.Web.Common
-
-This also means that we have to use "InternalsVisibleTo" for the new projects since these should be able to access the internal classes since they will when they get merged.

-- [Getting Started](#getting-started)
-- [Documentation](#documentation)
-- [Community](#join-the-umbraco-community)
-- [Contributing](#contributing)
+You can get started using the following commands on Windows, Linux and MacOS (after installing the [.NET Runtime and SDK](https://docs.umbraco.com/umbraco-cms/fundamentals/setup/requirements)):

-## Getting Started
-
-[Umbraco Cloud](https://umbraco.com/cloud) is the easiest and fastest way to use Umbraco yet, with full support for all your custom .NET code and integrations. You're up and running in less than a minute, and your life will be made easier with automated upgrades and a built-in deployment engine. We offer a free 14-day trial, no credit card needed.
-
-If you want to DIY, then you can [download Umbraco]((https://our.umbraco.com/download)) either as a ZIP file or via NuGet. It's the same version of Umbraco CMS that powers Umbraco Cloud, but you'll need to find a place to host it yourself, and handling deployments and upgrades will be all up to you.

+## Before you start
+
+
+### Code of Conduct
+
+This project and everyone participating in it, is governed by the [our Code of Conduct][code of conduct].
+
+### What can I contribute?
+
+We categorise pull requests (PRs) into two categories:
+
+| PR type   | Definition                                                   |
+| --------- | ------------------------------------------------------------ |
+| Small PRs | Bug fixes and small improvements - can be recognized by seeing a small number of changes and possibly a small number of new files. |
+| Large PRs | New features and large refactorings - can be recognized by seeing a large number of changes, plenty of new files, updates to package manager files (NuGet’s packages.config, NPM’s packages.json, etc.). |
+
+We’re usually able to handle small PRs pretty quickly. A community volunteer will do the initial review and flag it for Umbraco HQ as “community tested”. If everything looks good, it will be merged pretty quickly [as per the described process][review process].
+
+We would love to follow the same process for larger PRs but this is not always possible due to time limitations and priorities that need to be aligned. We don’t want to put up any barriers, but this document should set the correct expectations. 
+
+Not all changes are wanted, so on occasion we might close a PR without merging it but if we do, we will give you feedback why we can't accept your changes. **So make sure to [talk to us before making large changes][making larger changes]**, so we can ensure that you don't put all your hard work into something we would not be able to merge.
+
+#### Making larger changes
+
+[making larger changes]: #making-larger-changes
+
+Please make sure to describe your larger ideas in an [issue (bugs)][issues] or [discussion (new features)][discussions], it helps to put in mock up screenshots or videos. If the change makes sense for HQ to include in Umbraco CMS we will leave you some feedback on how we’d like to see it being implemented. 
+
+If a larger pull request is encouraged by Umbraco HQ, the process will be similar to what is described in the small PRs process above, we strive to feedback within 14 days. Finalizing and merging the PR might take longer though as it will likely need to be picked up by the development team to make sure everything is in order. We’ll keep you posted on the progress.
+
+#### Pull request or package?
+
+[pr or package]: #pull-request-or-package
+
+If you're unsure about whether your changes belong in the core Umbraco CMS or if you should turn your idea into a package instead, make sure to [talk to us][making larger changes].
+
+If it doesn’t fit in CMS right now, we will likely encourage you to make it into a package instead. A package is a great way to check out popularity of a feature, learn how people use it, validate good usability and fix bugs. Eventually, a package could "graduate" to be included in the CMS.
+
+#### Ownership and copyright
+
+It is your responsibility to make sure that you're allowed to share the code you're providing us. For example, you should have permission from your employer or customer to share code.
+
+Similarly, if your contribution is copied or adapted from somewhere else, make sure that the license allows you to reuse that for a contribution to Umbraco-CMS.
+
+If you're not sure, leave a note on your contribution and we will be happy to guide you.
+
+When your contribution has been accepted, it will be [MIT licensed][MIT license] from that time onwards.

+## Finding your first issue: Up for grabs
+
+Umbraco HQ will regularly mark newly created issues on the issue tracker with [the `community/up-for-grabs` tag][up for grabs issues]. This means that the proposed changes are wanted in Umbraco but the HQ does not have the time to make them at this time. We encourage anyone to pick them up and help out.
+
+If you do start working on something, make sure to leave a small comment on the issue saying something like: "I'm working on this". That way other people stumbling upon the issue know they don't need to pick it up, someone already has.
+
+## Making your changes
+
+Great question! The short version goes like this:
+
+1. **Fork**
+
+    Create a fork of [`Umbraco-CMS` on GitHub][Umbraco CMS repo]
+    
+    ![Fork the repository](img/forkrepository.png)
+    
+1. **Clone**
+
+    When GitHub has created your fork, you can clone it in your favorite Git tool
+    
+    ![Clone the fork](img/clonefork.png) 
+    
+1. **Switch to the correct branch**
+
+    Switch to the `contrib` branch
+
+1. **Build**
+
+    Build your fork of Umbraco locally as described in the build documentation: you can [debug with Visual Studio Code][build - debugging with code] or [with Visual Studio][build - debugging with vs].
+
+1. **Branch**
+
+    Create a new branch now and name it after the issue you're fixing, we usually follow the format: `temp-12345`. This means it's a temporary branch for the particular issue you're working on, in this case issue number `12345`.  Don't commit to `contrib`, create a new branch first.
+
+1. **Change**
+
+    Make your changes, experiment, have fun, explore and learn, and don't be afraid. We welcome all contributions and will [happily give feedback][questions].
+
+1. **Commit and push**
+
+    Done? Yay! 🎉
+
+    Remember to commit to your new `temp` branch, and don't commit to `contrib`. Then you can push the changes up to your fork on GitHub.
+
+#### Keeping your Umbraco fork in sync with the main repository
+[sync fork]: #keeping-your-umbraco-fork-in-sync-with-the-main-repository
+
+Once you've already got a fork and cloned your fork locally, you can skip steps 1 and 2 going forward. Just remember to keep your fork up to date before making further changes.
+
+To sync your fork with this original one, you'll have to add the upstream url. You only have to do this once:
+
+```
+git remote add upstream https://github.com/umbraco/Umbraco-CMS.git
+```
+
+Then when you want to get the changes from the main repository:
+
+```
+git fetch upstream
+git rebase upstream/contrib
+```
+
+In this command we're syncing with the `contrib` branch, but you can of course choose another one if needed.
+
+[More information on how this works can be found on the thoughtbot blog.][sync fork ext]
+
+#### Style guide
+
+To be honest, we don't like rules very much. We trust you have the best of intentions and we encourage you to create working code. If it doesn't look perfect then we'll happily help clean it up.
+
+That said, the Umbraco development team likes to follow the hints that ReSharper gives us (no problem if you don't have this installed) and we've added a `.editorconfig` file so that Visual Studio knows what to do with whitespace, line endings, etc.
+
+#### Questions?
+[questions]: #questions
+
+You can get in touch with [the core contributors team][core collabs] in multiple ways; we love open conversations and we are a friendly bunch. No question you have is stupid. Any question you have usually helps out multiple people with the same question. Ask away:
+
+- If there's an existing issue on the issue tracker then that's a good place to leave questions and discuss how to start or move forward.
+- If you want to ask questions on some code you've already written you can create a draft pull request, [detailed in a GitHub blog post][draft prs].
+- Unsure where to start? Did something not work as expected? Try leaving a note in the ["Contributing to Umbraco"][contrib forum] forum. The team monitors that one closely, so one of us will be on hand and ready to point you in the right direction.

+## Unwanted changes
+While most changes are welcome, there are certain types of changes that are discouraged and might get your pull request refused.
+Of course this will depend heavily on the specific change, but please take the following examples in mind.
+
+- **Breaking changes (code and/or behavioral) 💥** - sometimes it can be a bit hard to know if a change is breaking or not. Fortunately, if it relates to code, the build will fail and warn you.
+- **Large refactors 🤯** - the larger the refactor, the larger the probability of introducing new bugs/issues.  
+- **Changes to obsolete code and/or property editors ✍️**
+- **Adding new config options 🦾** - while having more flexibility is (most of the times) better, having too many options can also become overwhelming/confusing, especially if there are other (good/simple) ways to achieve it.
+- **Whitespace changes 🫥** - while some of our files might not follow the formatting/whitespace rules (mostly old ones), changing several of them in one go would cause major merge conflicts with open pull requests or other work in progress. Do feel free to fix these when you are working on another issue/feature and end up "touching" those files!
+- **Adding new extension/helper methods ✋** - keep in mind that more code also means more to maintain, so if a helper is only meaningful for a few, it might not be worth adding it to the core.
+
+While these are only a few examples, it is important to ask yourself these questions before making a pull request:
+
+- How many will benefit from this change?
+- Are there other ways to achieve this? And if so, how do they compare?
+- How maintainable is the change?
+- What would be the effort to test it properly?
+- Do the benefits outweigh the risks?
