+### Publishing outside GitLab CI/CD
+
+For `sbt publish` to work outside GitLab CI/CD, at least `gitlabDomain` and `gitlabProjectId` need to be defined:
+
+```sbt
+gitlabDomain := "gitlab.your-company.com"
+gitlabProjectId := GitlabProjectId("unicorn").some
+```
+
+(remember to set up the [Credentials](#Credentials))
+
 ### Testing
 
 Run `test` for regular unit tests (there are none at the moment).
