+This repository is to be used as a[git-subrepo]
+(https://github.com/ingydotnet/git-subrepo). See the instructions below in the
+[Git Subrepo Usage](#git-subrepo-usage) section
 
+## Tooling offered
+
+This repo offers:
+
+* Linter configuration for perl projects: `.perltidyrc`, `.perlcriticrc`,
+  `.proverc` & `.tidyallrc`.
+* Perlcritic policies that `os-autoinst/os-autoinst` and `os-autoinst/openQA`
+  share.
+* Useful tools for linting & testing:
+    * A `perlcritic` wrapper that will automatically add Perlcritic rules
+      defined under `lib/perlcritic` and
+      `external/os-autoinst-common/lib/perlcritic`.
+    * A `tidyall` wrapper that will validate the Perltidy version against the
+      `cpanfile` definition.
+* Example Github Actions for linting and unit testing for Perl.
+
+All files can be either copied or symlinked for any downstream repository
+consuming these tools.

+```bash
+cd your-repo

 was used.

 ### Pull
 
 To get the latest changes, you can pull:
 
-    % git subrepo pull ext/os-autoinst-common

 If that doesn't work for whatever reason, you can also simply reclone it like
