 Edit link configuration. You can then customize git repo link and display text.
 
+We have built-in recognition of common git services, you just need to configure the domain. If you're using a self-built service (like GitLab) you can specify or customize the link style.

+
+Available parameters:
+  - `:repo`: The `repo` you configured
+  - `:branch`: Ibid
+  - `:path`: `dir` + file path
