+# GitHub Actions Support Files
+
+This is a collection of scripts and files to support GitHub Actions.
+
+## Sending Notifications
+
+These scripts send CI notifications to Keybase by creating messages from templates and env vars passed from GitHub Actions.
+
+### Adding notifications to a GitHub Action
+
+```
+jobs:
+  build:
+    ...
+    - name: Notifications - Node Install
+      run: npm install
+      working-directory: .github/workflows/support-files/notifications
+    - name: Notifications - Send
+      env:
+        NYM_NOTIFICATION_KIND: "my-component"
+        GIT_BRANCH: "${GITHUB_REF##*/}"
+        KEYBASE_NYMBOT_USERNAME: "${{ secrets.KEYBASE_NYMBOT_USERNAME }}"
+        KEYBASE_NYMBOT_PAPERKEY: "${{ secrets.KEYBASE_NYMBOT_PAPERKEY }}"
+        KEYBASE_NYMBOT_TEAM: "${{ secrets.KEYBASE_NYMBOT_TEAM }}"
+        KEYBASE_NYM_CHANNEL: "ci-network-explorer"
+        IS_SUCCESS: "${{ job.status == 'success' }}"
+      uses: docker://keybaseio/client:stable-node
+      with:
+        args: .github/workflows/support-files/notifications/entry_point.sh
+```
+
+Notifications are run by adding the snippet above to a GitHub Action, and:
+
+1. Installing node packages needed at run time
+2. Set the env vars as required:
+    - `NYM_NOTIFICATION_KIND` matches the directory in `.github/workflows/support-files/${NYM_NOTIFICATION_KIND}` to provide the templates and extra scripting in `index.js`
+    - Keybase credentials, channel and other env vars for the status of the build and repo
+3. Replacing the default entry point shell script on the `keybaseio/client:stable-node` docker image to run `.github/workflows/support-files/notifications/entry_point.sh` 
+
+### Running locally
+
+You will need:
+- Node 16 LTS
+- npm
+
+Copy `.github/workflows/support-files/.env.example` to `.github/workflows/support-files/.env` and valid Keybase credentials.
+
+Then run `npm install` to get dependencies.
+
+Start development mode for the notification type you want either by passing the value as an env var called `NYM_NOTIFICATION_KIND` or set the `.env` file values correctly.
+
+```bash
+cd .github/workflows/support-files
+npm install
+cp .env.example .env
+vi .env
+npm run dev
+```
