+# Push registry app files to Supabase
+
+This action pushes new and modified `*.app.mjs/*.app.ts` files to Supabase.
+
+## Inputs
+
+### `changed_files`
+
+**Required** List of changed files.
+
+### `supabase_anon_key`
+
+**Required** Supabase key
+
+```
+...
+with:
+  format: json
+```
+
+in that way `steps.changed_files.outputs.all` will be converted into an array of strings
+
+## Example usage
+
+```yaml
+  - name: Upload modified or newly added *.app.mjs files to Supabase
+    uses: ./.github/actions/push-registry-app-files-supabase
+    with:
+      changed_files: ${{ steps.changed_files.outputs.all }}
+      supabase_anon_key: ${{ secrets.SUPABASE_ANON_KEY }}
+```
+
+## Local Development + Build
+
+Run the following command from this action directory to update `dist/index.js` if `src/index.js` has been modified:
+```bash
+cd .github/actions/push-registry-app-files-supabase
+npm run dev
+```
+
+The above command will build and run the dist/index.js. Commit the `dist` directory.
+You might want to change the `on` trigger to `push` event on your local branch when making changes to the action so you
+can test it on GitHub:
+
+## Master
+```yaml
+# .github/workflows/push-registry-app-files-supabase.yaml
+on:
+  pull_request:
+    branches:
+      - master
+    paths:
+      - 'components/**'
+```
+
+## During development
+```yaml
+# .github/workflows/push-registry-app-files-supabase.yaml
+on:
+  push:
+    branches:
+      - feature-branch-name
+    paths:
+      - 'components/**'
+      - '.github/actions/push-registry-app-files-supabase/**'
+```
