 ## How to use
 
 Once it's installed and configured, Git Credential Manager is called implicitly by Git.
 You don't have to do anything special, and GCM isn't intended to be called directly by the user.
-For example, when pushing (`git push`) to [Azure DevOps](https://dev.azure.com), [Bitbucket](https://bitbucket.org), or [GitHub](https://github.com), a window will automatically open and walk you through the sign-in process.
+For example, when pushing (`git push`) to [Azure DevOps][azure-devops], [Bitbucket][bitbucket], or [GitHub][github], a window will automatically open and walk you through the sign-in process.
 (This process will look slightly different for each Git host, and even in some cases, whether you've connected to an on-premises or cloud-hosted Git host.)
 Later Git commands in the same repository will re-use existing credentials or tokens that GCM has stored for as long as they're valid.
