-Runs a script that checks for stored Git credentials, populating them with user's Coder credentials when missing. 
+Runs a script that checks for stored Git credentials `user.name` and `user.email`, populating them with workspace owner's credentials when missing. 
 
 
 ## Examples
 
+### Using Workspace owner
+The credentials can be populated from the workspace owner's information.
+
 ```hcl
+module "git-config" {
+  source = "git::https://github.com/coder/modules.git//git-config?ref=git-config"
+  agent_id = coder_agent.main.id
+  username = data.coder_workspace.me.owner
+  user_email = data.coder_workspace.me.owner_email
+}
+```
+
+### Custom credentials
+Credentials can also be set manually.
 
+```hcl
+module "git-config" {
+  source = "git::https://github.com/coder/modules.git//git-config?ref=git-config"
+  agent_id = coder_agent.main.id
+  username = "michael"
+  user_email = "michael@example.com"
+}
 ```
