 being, the most both sane and GitHub-friendly way of communicating.
 
-## The git pre-commit hook
-
-This hook is checking for src/deps/facilio in the file list that
-only lets you go through with the operation if a specific env var is set
-
-why is that? we don't use a fork of facilio. we use their repo as submodule. on
-build, we apply a patch to the submodule. after applying, the submodule is
-dirty. it refers to a new head only present on the current machine. if we were
-to commit the submodule now and push those changes, future git submodule update
---init calls will fail on fresh clones of the repo. We want to avoid this
-mistake that easily happens if you use a `git add . && git commit` workflow. On
-the other hand, if upstream facilio changes, we still want to be able to upgrade
-to it by pulling the changes and recording the new head via git commit to our
-own repo. Hence, just ignoring the submodule via `.gitignore` is not an option.
-That's why we introduced the hook (// that gets installed on build.)
