+## Downloading and auto-updating from a Git repository
+
+To automatically pull website contents from a Git repository on a schedule:
+
+1. `abra app config YOURAPPDOMAIN`
+2. Add or uncomment these lines and configure your repository and update schedule:
+```
+COMPOSE_FILE="$COMPOSE_FILE:compose.git-pull.yml"
+GIT_REPO_URL="https://git.coopcloud.tech/yourorg/yourrepo"
+GIT_BRANCH=main
+CRON_SCHEDULE="*/10 * * * *"  # Default: every 10 minutes
+```
+3. `abra app deploy YOURAPPDOMAIN`
+4. As the git-pull service has `replicas: 0` in `compose.git-pull.yml` and doesn't run by itself. It requires either:
+- Deploying an instance of the [`coop-cloud/swarm-cronjob`] recipe on your server, OR
+- A manual cronjob on the server running: `docker service scale <app_domain_tld>_git=1`

 ## Allowing upload via SSH/SFTP

 4. Test the SSH connection: `ssh -p 2220 sftp@YOURAPPDOMAIN`
 5. You can copy local files into the server's web root with a command like: `scp -r -P 2220 * sftp@YOURAPPDOMAIN:/content`
 
+## Redirect options
+
+### Full redirect (of all URLs under specific path)
+
+To redirect the entire domain or a specific path to another URL:
+
+1. `abra app config YOURAPPDOMAIN`
+2. Add or uncomment these lines:
+```
+REDIRECT_FROM_PATH=/  # Path to redirect from (with trailing slash)
+REDIRECT_TO_URL=https://example.com/website/  # Target URL (with trailing slash)
+REDIRECT_TYPE=redirect  # Use "redirect" (for HTTP 302) or "permanent" (for 301)
+```
+3. `abra app deploy YOURAPPDOMAIN`
+
+This will redirect all requests matching `REDIRECT_FROM_PATH` to `REDIRECT_TO_URL`, carrying over the path. For example, `/blog/post` would redirect to `https://example.com/website/blog/post`.
+
+### Fallback redirect for paths not matching a file
+
+To serve static files normally but redirect requests for all non-existent paths to a dynamic site:
+
+1. `abra app config YOURAPPDOMAIN`
+2. Add or uncomment these lines:
+```
+FALLBACK_REDIRECT_URL=https://dynamic-site.example.com
+FALLBACK_REDIRECT_TYPE=302
+```
+3. `abra app deploy YOURAPPDOMAIN`
+
+This is useful for serving a static site alongside a dynamic one (that is running on a different [sub]domain) on the same domain. Existing static files are served directly, while missing URLs are redirected to the dynamic site with the full path preserved.
+
+### Single-page application (SPA) handler
+
+Similarly, to serve all non-existent paths with a single HTML file (common for React, Vue, etc.):
+
+1. `abra app config YOURAPPDOMAIN`
+2. Add or uncomment this line:
+```
+SINGLE_PAGE_SITE_HANDLER=/index.html
+```
+3. `abra app deploy YOURAPPDOMAIN`
+
+This will serve the contents `/index.html` (as a rewrite rather than a redirect) for any route that doesn't match an existing file, allowing client-side routing to work properly.
+
+**Note:** `FALLBACK_REDIRECT_URL` and `SINGLE_PAGE_SITE_HANDLER` are mutually exclusive options.
