+# diy-steward
+Set up your very own Scala Steward!
+
+1. Use this template to create a new repo.
+2. Create a new GitHub App.
+    - Personal app: https://github.com/settings/apps/new
+    - Org app: `https://github.com/organizations/[your-org]/settings/apps/new`
+3. You can disable the Webhook and set the App homepage to your new repo.
+4. Grant the App the following permissions:
+    - Actions: Read-only
+    - Contents: Read and write
+    - Metadata: Read-only
+    - Pull requests: Read and write
+    - Workflows: Read and write (this is required to support the sbt-github-actions plugin)
+5. Create the app. Note the app ID, we will need it later.
+6. Generate and download an App private key.
+7. Install the app on your repos. It _must_ be installed in this repo and it should also be installed on any repo you want steward updates on.
+    - Personal: `https://github.com/settings/apps/[your-app-name]/installations`
+    - Org: `https://github.com/organizations/[your-org]/settings/apps/[your-app-name]/installations`
+8. In this repo, set the secret `APP_PRIVATE_KEY` to the contents of the private key you downloaded.
+9. Finally, edit [`.github/workflows/steward.yml`](.github/workflows/steward.yml):
+    - Replace the 3 instances of `123456` with your app ID (see also [#1](https://github.com/armanbilge/diy-steward/issues/1))
+    - Replace the 2 instances of `your-app-name` with your app's name.
+    - Tweak the scheduling as you see fit. Default is ["At minute 0 past every 4th hour."](https://crontab.guru/#0_*/4_*_*_*)
+10. That's it! To manually trigger your new steward, navigate to the Actions tab on this repo, select the Scala Steward workflow, and click "Run Workflow".
+
+Please open issues or PRs with any improvements and fixes for this template. Thank you!
+
+## Running with repos.md
+
+If you [use a repos.md file to list repositories](https://github.com/scala-steward-org/scala-steward-action#using-a-file-to-list-repositories), be sure to remove the `github-app-id` and `github-app-key` from the `scala-steward-action` configuration.  For example:
+
+```yaml
+      - name: Launch Scala Steward
+        uses: scala-steward-org/scala-steward-action@v2
+        with:
+          github-token: ${{ steps.generate-token.outputs.token }}
+          author-email: 123456+your-app-name[bot]@users.noreply.github.com
+          author-name: your-app-name[bot]
+          repos-file: 'repos.md'
+```
