   * don't use `import-debian-package` on existing repositories, it does not
     attempt to merge `apertis/*` branches and instead it re-sets them to new
     branches based on the freshly imported Debian package
+* Add a `debian/apertis/component` file reflecting the repository component it is part of (for instance, `target`)
+  * check out the apertis repository: `git checkout apertis/v2021dev0`
+  * add the component file: `echo target > debian/apertis/component`
+  * add the component file to git: `git add debian/apertis/component`
+  * commit the file: `git commit -m "Add d/apertis/component file pointing to target" debian/apertis/component`
 * create an empty project on GitLab under the `pkg/*` namespaces (for instance, `pkg/target/hello`)
 * configure the origin remote on your local git: `git remote add origin git@gitlab.apertis.org:pkg/target/hello`
 * push your local git contents to the newly created GitLab project: `git push --all --follow-tags origin`
