 Conversely, if you are working on front-end only, you want to build the back-end once and then run it. Before you do so, update the configuration in `appSettings.json` to add the following under `Umbraco:Cms:Security`:
 
-```json
+```
 "BackOfficeHost": "http://localhost:5173",
 "AuthorizeCallbackPathName": "/oauth_complete",
 "AuthorizeCallbackLogoutPathName": "/logout",

-}

-> [!NOTE]
-> If you get stuck in a login loop, try clearing your browser cookies for localhost, and make sure that the `BackOfficeTokenCookie` settings are correct. Namely, that `SameSite` should be set to `None` when running the front-end server separately.

-## 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`

-- NEVER CANCEL: Set timeout to 5+ minutes
-
-### Integration Tests (.NET)
-- Location: tests/Umbraco.Tests.Integration/
-- Run: `dotnet test tests/Umbraco.Tests.Integration/Umbraco.Tests.Integration.csproj --configuration Release --verbosity minimal`
-- NEVER CANCEL: Set timeout to 10+ minutes
-
-### Frontend Tests
-- Location: src/Umbraco.Web.UI.Client/
-- Run: `npm test` (requires `npx playwright install` first)
-- Frontend tests use Web Test Runner with Playwright
-
-### Acceptance Tests (E2E)
-- Location: tests/Umbraco.Tests.AcceptanceTest/
-- Requires running Umbraco application and configuration
-- See tests/Umbraco.Tests.AcceptanceTest/README.md for detailed setup (requires `npx playwright install` first)
-

-- **Umbraco.Web.UI.Login**: Separate login screen frontend
-- **Umbraco.Core**: Core domain models and interfaces
-- **Umbraco.Infrastructure**: Data access and infrastructure
-- **Umbraco.Cms**: Main CMS package
-
-### API Projects
-- **Umbraco.Cms.Api.Management**: Management API
-- **Umbraco.Cms.Api.Delivery**: Content Delivery API
-- **Umbraco.Cms.Api.Common**: Shared API components
-
-### Persistence Projects
-- **Umbraco.Cms.Persistence.SqlServer**: SQL Server support
-- **Umbraco.Cms.Persistence.Sqlite**: SQLite support
-- **Umbraco.Cms.Persistence.EFCore**: Entity Framework Core abstractions
-
-### Test Projects
-- **Umbraco.Tests.UnitTests**: Unit tests

-- **Umbraco.Tests.AcceptanceTest**: End-to-end tests with Playwright
-- **Umbraco.Tests.Common**: Shared test utilities
-
-## Common Tasks
-
-### Running Umbraco in Different Modes
-
-**Production Mode (Standard Development)**
-Use this for backend development, testing full builds, or when you don't need hot reloading:
-1. Build frontend assets: `cd src/Umbraco.Web.UI.Client && npm run build:for:cms`
-2. Run backend: `cd src/Umbraco.Web.UI && dotnet run --no-build`
-3. Access backoffice: `https://localhost:44339/umbraco`
-4. Application uses compiled frontend from `wwwroot/umbraco/backoffice/`
-
-**Vite Dev Server Mode (Frontend Development with Hot Reload)**
-Use this for frontend-only development with hot module reloading:
-1. Configure backend for frontend development - Add to `src/Umbraco.Web.UI/appsettings.json` under `Umbraco:CMS:Security`:
-   ```json
-   "BackOfficeHost": "http://localhost:5173",
-   "AuthorizeCallbackPathName": "/oauth_complete",
-   "AuthorizeCallbackLogoutPathName": "/logout",
-   "AuthorizeCallbackErrorPathName": "/error",
-   "BackOfficeTokenCookie": {
-     "Enabled": true,
-     "SameSite": "None"
-   }
-   ```
-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`
-4. Access backoffice: `http://localhost:5173/` (no `/umbraco` prefix)
-5. Changes to TypeScript/Lit files hot reload automatically
-
-**Important:** Remove the `BackOfficeHost` configuration before committing or switching back to production mode.
-
-### 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.
