[Here is a list of all of the available template variables](https://github.com/JasonEtco/actions-toolkit#toolscontext). You can also use environment variables:

+```yaml
+- uses: JasonEtco/create-an-issue@v2
+  env:
+    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+    ADJECTIVE: great

+Environment variables are pretty {{ env.ADJECTIVE }}, right?
