-### Development
-Grub-btrfs uses a rudimentary system of automatic versioning to tell apart different commits. This is helpful when users report problems and it is not immediately clear what version they are using. 
-We therefore have the following script in `.git/hooks/pre-commit`:
-
-``` bash
-#!/bin/sh
-
-echo "Doing pre commit hook with version bump"
-version="$(git describe --tags --abbrev=0)-$(git rev-parse --abbrev-ref HEAD)-$(date -u -Iseconds)"
-echo "New version is ${version}"
-sed -i "s/GRUB_BTRFS_VERSION=.*/GRUB_BTRFS_VERSION=${version}/" config
-git add config
-```
-
-This automatically sets the version in the `config`-file to `[lasttag]-[branch-name]-[current-date-in-UTC]`.
-In order to create a Tag we don't want to have this long version. In this case we set the version manually in `config` and commit with `git commit --no-verify`. This avoids running the hook.
