-If you're not sure which GitHub integration you need to configure, please take a look at the URL. URLs like `https://github.com/org-name` are usually for GitHub-hosted accounts and should use the regular GitHub (not GitHub Enterprise) integration. See [Install](#install) for more details.
+There are two types of GitHub integrations, so make sure you're choosing the correct one:
+- [GitHub](#installing-github) - For regular GitHub accounts, these will have URLs like `https://github.com/org-name`. Follow the '[Installing GitHub](#installing-github)' instructions, **do not use the GitHub Enterprise integration**.
+- [GitHub Enterprise](#installing-github-enterprise) - For GitHub Enterprise Cloud or GitHub Enterprise Server instances. Some example URLs:
+  - `https://github.org-name.com`
+  - `https://github.com/enterprises/org-name`
+  - `https://org-name.ghe.com/`
 
-Self-hosted GitHub Enterprise accounts typically have URLs that look more like `https://github.org-name.com` (or some other customization of the domain). In this case, you should configure the [GitHub Enterprise integration](#github-enterprise).

For these accounts, follow the '[Installing GitHub Enterprise](#installing-github-enterprise)' instructions, **do not use the regular GitHub integration**.
