+You'll need to configure Wrangler using GitHub's Secrets feature - go to "Settings -> Secrets" and add your Cloudflare API token (for help finding this, see the [Workers documentation](https://developers.cloudflare.com/workers/quickstart/#api-token)). Your API token is encrypted by GitHub, and the action won't print it into logs, so it should be safe!

-With your API key and email set as secrets for your repository, pass them to the action in the `with` block of your workflow. Below, I've set the secret names to `CF_API_KEY` and `CF_EMAIL`:
+`wrangler-action` also supports using your [global API key and email](https://developers.cloudflare.com/workers/quickstart/#global-api-key) as an authentication method, although API tokens are preferred. Pass in `apiKey` and `email` to the GitHub Action to use this method:

-Optionally, you can also pass an `environment` key to the action.

+## Configuration
+
+If you're using Wrangler's [environments](https://github.com/cloudflare/wrangler/blob/master/docs/content/environments.md) feature, you can customize _where_ the action deploys to by passing an `environment` in the `with` block of your workflow:

+        apiToken: ${{ secrets.CF_API_TOKEN }}
         environment: 'production'
 ```
 
+If you need to install a specific version of Wrangler to use for deployment, you can also pass the input `wranglerVersion` to install a specific version of Wrangler from NPM. This should be a [SemVer](https://semver.org/)-style version number, such as `1.6.0`:
+
+```yaml

+        wranglerVersion: '1.6.0'

+
 Optionally, you can also pass a `workingDirectory` key to the action. This will allow you to specify a subdirectory of the repo to run the Wrangler command from.
