 ```
 
+*NOTE*: The `extra_context` spec adds a map of key/value pairs that may be expected in the `runner_install_template`.
+The `runner_install_template` allows us to completely override the script that installs and starts the runner. In the example above, I have added a copy of the current template from `garm-provider-common`, with the adition of:
+
+```bash
+{{- if .ExtraContext.GolangDownloadURL }}
+curl -LO {{ .ExtraContext.GolangDownloadURL }}
+rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.22.4.linux-amd64.tar.gz
+export PATH=$PATH:/usr/local/go/bin
+{{- end }}
+```
+*NOTE*: `runner_install_template` is a [golang template](https://pkg.go.dev/text/template), which is used to install the runner. An example on how you can extend the currently existing template with a function that downloads, extracts and installs Go on the runner is provided above.
+
+
 To set it on an existing pool, simply run:
 
 ```bash
