+## Getting started
+
+To get started, do the following:
+
+1. If you want to deploy to W3C /TR:
+   1. [Request an Echidna token][request-token] for your spec (W3C Team Members and Chairs only!).
+   1. [Save the token][save-token] as a "Secret" named `ECHIDNA_TOKEN` in the spec's repository's settings.
+1. Create a `.github/workflows/auto-publish.yml` file at the root of the spec's repository.
+1. In the `auto-publish.yml`, copy-paste and modify one of the [examples](examples.md) below that suits your needs. Most typical one:
+
+   ```yml
+   # Inside .github/workflows/auto-publish.yml
+   name: Automatic Publication 
+
+   on:
+     pull_request: {}
+     push:
+       branches: [main]
+
+   jobs:
+     validate-and-publish:
+       name: Validate and Publish to TR
+       runs-on: ubuntu-20.04
+       steps:
+         - uses: actions/checkout@v2
+         - uses: w3c/spec-prod@v2
+           with:
+             TOOLCHAIN: respec # or bikeshed
+             W3C_ECHIDNA_TOKEN: ${{ secrets.ECHIDNA_TOKEN }}
+             W3C_WG_DECISION_URL: " See Options for URLs! "
+             # Convert Editor's Draft to Working Draft!
+             W3C_BUILD_OVERRIDE: |
+               specStatus: WD
+   ```
