+## Custom pull request URLs
+
+Some git provider setups (e.g. on-premises GitLab) can have distinct URLs for git-related calls and
+the web interface/API itself. To work with those, Lazygit needs to know where it needs to create
+the pull request. You can do so on your `config.yml` file using the following syntax:
+
+```yaml
+services:
+  "<gitDomain>": "<provider>:<webDomain>"
+```
+
+Where:
+
+- `gitDomain` stands for the domain used by git itself (i.e. the one present on clone URLs), e.g. `git.work.com`
+- `provider` is one of `github`, `bitbucket` or `gitlab`
+- `webDomain` is the URL where your git service exposes a web interface and APIs, e.g. `gitservice.work.com`
