+GCM requires Gitea v1.17.3 or later.
+
+## Config for a custom instance
+
+1. In Settings / Applications, create an OAuth application, unchecking the
+*Confidential* option (if this option is missing, the version of Gitea is too
+old)
+1. Copy the application ID and configure
+`git config --global credential.https://gitea.example.com.GiteaDevClientId <APPLICATION_ID>`
+1. Copy the application secret and configure
+`git config --global credential.https://gitea.example.com.GiteaDevClientSecret
+<APPLICATION_SECRET>`
+1. Configure authentication modes to include 'browser'
+`git config --global credential.https://gitea.example.com.GiteaAuthModes browser`
+1. For good measure, configure
+`git config --global credential.https://gitea.example.com.provider gitea`.
+This may be necessary to recognise the domain as a Gitea instance.
+1. Verify the config is as expected
+`git config --global --get-urlmatch credential https://gitea.example.com`
+
+## Clearing config
+
+### Clearing config
+
+```console
+    git config --global --unset-all credential.https://gitea.example.com.GiteaDevClientId

+    git config --global --unset-all credential.https://gitea.example.com.provider

+  2. Personal access token
+  3. Username/password
