+   where you cloned the `gitlab-ce` repository and then do:
 
     ```
-    grep -nR "lfs_administration.md" doc/

+Things to note:
 
+- Since we also use inline documentation, except for the documentation itself,
+  the document might also be referenced in the views of GitLab (`app/`) which will
+  render when visiting `/help`, and sometimes in the testing suite (`spec/`).
+- The above `grep` command will search in the `app/`, `doc/` and `spec/`
+  directories for `workflow/lfs/lfs_administration` and `lfs/lfs_administration`

+  You may ask why the two greps. Since we use relative paths to link to
+  documentation, sometimes it might be useful to search a path deeper.
+- The `*.md` extension is not used when a document is linked to GitLab's
+  built-in help page, that's why we omit it in `grep`.
