-# 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
