-Our convention of doing it is:
-
-_Area: Description (closes #IssueID)_
-
-1. Start by specifying the area. Fx the feature name(UFM, Tiptap etc.) or specific section (migrations, relations, segmentation).

-# **Contributing to Localization in the Backoffice**
-
-Do you want to help keep our translations accurate and up to standard? 🌍✨
-
-Your input makes a real difference! By reviewing, refining, or suggesting improvements, you ensure that our translations remain clear, consistent, and user-friendly for everyone.
-
-
-## **How Can I Contribute?**
-
-To contribute to localization in the Backoffice, follow this step-by-step guide:
-
-
-### **1. Change the Language in Backoffice**
-
-
-
-1. Open the Backoffice, click on your profile icon in the top-right corner, and select "Edit." 
-
-
-
-![Menubar profile image](/.github/img/contributing/ProfileImage.png "Menubar profile image")
-
-
-
-![Edit button inside profile](/.github/img/contributing/editBtn.png "Edit button inside profile")
-
-
-2. Under "UI Culture," select the language you want to review from the dropdown menu. 
-
-
-
-![Dropdown of languages in Umbraco](/.github/img/contributing/uiCulture.png "Dropdown of languages in Umbraco")
-
-
-
-### **2. Find a Translation Error**
-
-
-
-1. Navigate through the Backoffice and check if everything is translated correctly. 
-
-2. When you find a translation error, right-click on it and select "Inspect." 
-
-3. Look for the nearest element that starts with `umb-` and has a name indicating something specific to the given location. 
- 
-    **Example:**  
-
-    * The closest parent element should be specific, such as `umb-document-type-workspace-view-settings` instead of a generic element like `umb-property-layout.`
-
-
-### **3. Find the Code in VS Code**
-
-
-
-1. Open VS Code and search for the nearest `umb-` element you identified. 
-
-
-
-![Search for nearest umb element in code](/.github/img/contributing/searchInVsCode.png "Search for nearest umb element in code")
-
-2. Scroll down to find `render() {` and look for the element label that needs updating. 
-
-
-![Find render and label in code](/.github/img/contributing/renderCode.png "Find render and label in code")
-
-3. If the label is hardcoded, it must be updated. 
- 
-    **Example:**  
-    `label="Vary by culture"`
-
-
-### **4. Find the Correct Translation**
-
-
-
-1. Open the `en.ts` or `en-us.ts` file and search for relevant keywords. \
- \
-    **Example:** 
-
-    * If the text is "Vary by culture," search for `vary`, `culture`, or `Vary by culture`. 
-
-
-2. Once you find the translation, take the element name and search for it in the target language file (e.g., `da-dk.ts` for Danish). 
-
-
-![Search for translation in language files](/.github/img/contributing/searchingThroughLanguageFiles.png "Search for translation in language files")
-
-3. If a translation exists, insert it into the label element found earlier. 
-
-
-
-### **5. Insert the Translation**
-
-To display the new translation correctly, insert the following code inside the label element:
-
-`${this.localize.term('action_key')}`
-
-Replace `action_key` with the correct translation key.
-
-**Example:**
-
-`${this.localize.term('contentTypeEditor_allowVaryByCulture')}`
-
-![Localization code snippet](/.github/img/contributing/localizationCodeSnippetInCode.png "Localization code snippet")
-
-
-Save the changes and return to the Backoffice to see the update.
-
-
-![Changes in backoffice after changes in code](/.github/img/contributing/changedBackofficeAfterLocalization.png "Changes in backoffice after changes in code")
-
-
-
-### **6. Commit and Push**
-
-
-
-1. Commit your changes to a new temporary branch (avoid committing directly to `contrib`). 
-
-2. Push the changes to your fork on GitHub.
-
-
-### **7. Create a Pull Request**
-
-
-
-1. In your forked repository on GitHub (`https://github.com/[YourUsername]/Umbraco-CMS`), a banner will appear stating that you pushed a new branch. 
-
-2. Click the button to create a pull request and follow the instructions.
-
-
-## **I Can’t Find the Correct Translation**
-
-If you can’t find the translation you need, it may not exist yet. In this case, you can create a new action with related keys.
-
-
-### **1. Ensure It Doesn’t Already Exist**
-
-Search thoroughly in `en.ts` or `en-us.ts` for all relevant keywords.
-
-
-### **2. Create an Action**
-
-
-
-1. Choose a meaningful name for the action to avoid confusion. \
- \
- **Example:** Translation for the Data Type "Color Picker." 
-
-    * **Good name:** `colorPickerConfigurations`
-    * **Bad name:** `colorpicker`
-2. A specific action name prevents unnecessarily long key names. 
-
-3. Define the action: 
-
-
-
-### **3. Create Keys**
-
-
-
-1. Use clear and descriptive key names. \
- \
- **Example:**
-    * **Good name:** `colorsTitle`
-    * **Bad name:** `colors`
-2. Add the necessary keys inside the action with proper translations. 
-
-
-
-![Action and related Keys in language files](/.github/img/contributing/actionAndKeys.png "Action and related Keys in language files")
-
-
-
-## **I Can’t Find a <code>render()</code> Code in VS Code**
-
-In some cases, such as Data Types, the label might not be inside `render()`. Instead, it may be in a manifest file.
-
-
-### 1. Search for the Text
-
-Copy the text from the Backoffice and search for it in the code.
-
-
-### 2. Open the Manifest File
-
-Once you find the relevant manifest file, open it to confirm you’re in the right place.
-
-
-### 3. Change the Label
-
-In Markdown files, localization is slightly different. Instead of:
-`${this.localize.term('action_key')}`
-
-Use: `#action_key`
-
-**Example:**
-`#colorPickerConfigurations_showLabelTitle`
-
-### 4. Change the Description
-
-For descriptions in Markdown files, use:
-`{umbLocalize: action_key}`
-
-**Example:**
-`{umbLocalize: colorPickerConfigurations_showLabelDescription}`
-
-
-### 5. Save and Verify
-
-Once all changes are made, your manifest should look something like this:
-
-
-![Localization changes to manifest files](/.github/img/contributing/finishedManifestAfterLocalizatonChanges.png "Localization changes to manifest files")
-

-
-## Working Effectively
-
-Bootstrap, build, and test the repository:
-
-- Install .NET SDK (version specified in global.json):
-  - `curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin --version $(jq -r '.sdk.version' global.json)`
-  - `export PATH="/home/runner/.dotnet:$PATH"`
-- Install Node.js (version specified in src/Umbraco.Web.UI.Client/.nvmrc):
-  - `curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.0/install.sh | bash`
-  - `export NVM_DIR="$HOME/.nvm" && [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"`
-  - `nvm install $(cat src/Umbraco.Web.UI.Client/.nvmrc) && nvm use $(cat src/Umbraco.Web.UI.Client/.nvmrc)`
-- Fix shallow clone issue (required for GitVersioning):
-  - `git fetch --unshallow`
-- Restore packages:
-  - `dotnet restore` -- takes 50 seconds. NEVER CANCEL. Set timeout to 90+ seconds.
-- Build the solution:
-  - `dotnet build` -- takes 4.5 minutes. NEVER CANCEL. Set timeout to 10+ minutes.
-- Install and build frontend:
-  - `cd src/Umbraco.Web.UI.Client`
-  - `npm ci --no-fund --no-audit --prefer-offline` -- takes 11 seconds.
-  - `npm run build:for:cms` -- takes 1.25 minutes. NEVER CANCEL. Set timeout to 5+ minutes.
-- Install and build Login
-  - `cd src/Umbraco.Web.UI.Login`
-  - `npm ci --no-fund --no-audit --prefer-offline`
-  - `npm run build`
-- Run the application:
-  - `cd src/Umbraco.Web.UI`
-  - `dotnet run --no-build` -- Application runs on https://localhost:44339 and http://localhost:11000
-
-## Validation
-
-- ALWAYS run through at least one complete end-to-end scenario after making changes.
-- Build and unit tests must pass before committing changes.
-- Frontend build produces output in src/Umbraco.Web.UI.Client/dist-cms/ which gets copied to src/Umbraco.Web.UI/wwwroot/umbraco/backoffice/
-- Always run `dotnet build` and `npm run build:for:cms` before running the application to see your changes.
-- For login-only changes, you can run `npm run build` from src/Umbraco.Web.UI.Login and then `dotnet run --no-build` from src/Umbraco.Web.UI.
-- For frontend-only changes, you can run `npm run dev:server` from src/Umbraco.Web.UI.Client for hot reloading.
-- Frontend changes should be linted using `npm run lint:fix` which uses Eslint.
-
-## Testing
-
-### Unit Tests (.NET)
-- Location: tests/Umbraco.Tests.UnitTests/
-- Run: `dotnet test tests/Umbraco.Tests.UnitTests/Umbraco.Tests.UnitTests.csproj --configuration Release --verbosity minimal`

-
-## Common Tasks
-
-### Frontend Development
-For frontend-only changes:
-1. Configure backend for frontend development:
-   ```json
-   <!-- Add to src/Umbraco.Web.UI/appsettings.json under Umbraco:Cms:Security: -->
-   ```json
-   "BackOfficeHost": "http://localhost:5173",
-   "AuthorizeCallbackPathName": "/oauth_complete",
-   "AuthorizeCallbackLogoutPathName": "/logout",
-   "AuthorizeCallbackErrorPathName": "/error"
-   ```
-2. Run backend: `cd src/Umbraco.Web.UI && dotnet run --no-build`
-3. Run frontend dev server: `cd src/Umbraco.Web.UI.Client && npm run dev:server`
-
-### Backend-Only Development
-For backend-only changes, disable frontend builds:
-- Comment out the target named "BuildStaticAssetsPreconditions" in src/Umbraco.Cms.StaticAssets.csproj:
-  ```
-  <!--<Target Name="BuildStaticAssetsPreconditions" BeforeTargets="AssignTargetPaths">
-    [...]
-  </Target>-->
-  ```
-- Remember to uncomment before committing
-
-### Building NuGet Packages
-To build custom NuGet packages for testing:
-```bash
-dotnet pack -c Release -o Build.Out
-dotnet nuget add source [Path to Build.Out folder] -n MyLocalFeed
-```
-
-### Regenerating Frontend API Types
-When changing Management API:
-```bash
-cd src/Umbraco.Web.UI.Client
-npm run generate:server-api-dev
-```
-Also update OpenApi.json from /umbraco/swagger/management/swagger.json
-
-## Database Setup
-
-Default configuration supports SQLite for development. For production-like testing:
-- Use SQL Server/LocalDb for better performance
-- Configure connection string in src/Umbraco.Web.UI/appsettings.json
-
-## Clean Up / Reset
-
-To reset development environment:
-```bash
-# Remove configuration and database
-rm src/Umbraco.Web.UI/appsettings.json
-rm -rf src/Umbraco.Web.UI/umbraco/Data
-
-# Full clean (removes all untracked files)
-git clean -xdf .
-```
-
-## Version Information
-
-- Target Framework: .NET (version specified in global.json)
-- Current Version: (specified in version.json)
-- Node.js Requirement: (specified in src/Umbraco.Web.UI.Client/.nvmrc)
-- npm Requirement: Latest compatible version
-
-## Known Issues
-
-- Build requires full git history (not shallow clone) due to GitVersioning
-- Some NuGet package security warnings are expected (SixLabors.ImageSharp vulnerabilities)
-- Frontend tests require Playwright browser installation: `npx playwright install`
-- Older Node.js versions may show engine compatibility warnings (check .nvmrc for current requirement)
-
-## Timing Expectations
-
-**NEVER CANCEL** these operations - they are expected to take time:
-
-| Operation | Expected Time | Timeout Setting |
-|-----------|--------------|-----------------|
-| `dotnet restore` | 50 seconds | 90+ seconds |
-| `dotnet build` | 4.5 minutes | 10+ minutes |
-| `npm ci` | 11 seconds | 30+ seconds |
-| `npm run build:for:cms` | 1.25 minutes | 5+ minutes |
-| `npm test` | 2 minutes | 5+ minutes |
-| `npm run lint` | 1 minute | 5+ minutes |
-| Unit tests | 1 minute | 5+ minutes |
-| Integration tests | Variable | 10+ minutes |
-
-Always wait for commands to complete rather than canceling and retrying.
