+# This is an example hook script.  It will be run by 'mkinitramfs'

+# package is installed, or when the administrator runs 'mkinitramfs'
+# by hand to update an initramfs image.

+

+
+## <a name="preparations">2. Preparations</a>
+
+1. Install required software:
+
+        # apt-get install git git-buildpackage dpkg-dev
+
+1. Set environment variables (e.g. through your ~/.bashrc or ~/.zshrc) for devscripts (gbp dch):
+
+        export DEBEMAIL=$mailaddress
+        export DEBFULLNAME=$yourname
+
+1. Set user name and email address for git (drop the --global option to use configuration per-repo basis):
+
+        % git config --global user.name  "$yourname"
+        % git config --global user.email "$mailaddress"
+
+1. <a name="checkout">Checkout repository (anonymous):</a>
+
+        % git clone https://salsa.debian.org/kernel-team/initramfs-tools.git
+        % cd initramfs-tools
+
+1. Checkout repository (with developer access):
+
+        % git clone ssh://git@salsa.debian.org/kernel-team/initramfs-tools.git
+        % cd initramfs-tools
+
+***
+
+## <a name="workflow">3. Workflow for daily work</a>
+
+### <a name="newfeature">3.1 Implement new features</a>
+
+1. Checkout new branch and switch to it:
+
+        % git checkout -b $username/short-descr-of-new-feature
+
+1. Hack and commit work:
+
+        % $EDITOR $somefile
+        % git add $somefile
+        % git commit -s
+
+   **NOTE:** Use 'Closes: #BUGID' for closing a bugreport and 'Thanks: Fullname
+   &lt;mailaddress&gt;' for giving credits in your commit message. gbp dch will use
+   this information for generating the changelog using the --meta option later
+   on.
+
+1. Finally push your branch to Salsa:
+
+        % git push origin $username/short-descr-of-new-feature
+
+### <a name="merge">3.2 Merge branches</a>
+
+1. Switch to the branch you want to merge:
+
+        % git checkout $username/new-feature
+
+1. Rebase to master:
+
+        % git rebase master
+
+1. Switch to master branch and merge:
+
+        % git checkout master
+        % git merge $username/new-feature
+
+1. Push:
+
+        % git push
+
+1. After branch is merged delete branch on server and locally:
+
+        % git push origin :$username/short-descr-of-new-feature
+        % git branch -d $username/short-descr-of-new-feature
+
+1. If a branch is removed from the server it will stay locally. You can get of
+any stale remote branches locally by executing:
+
+        % git remote prune origin
+
+### <a name="test">3.3 Test specific branch</a>
+
+1. Checkout a specific branch iff branch is not already present locally:
+
+        % git checkout -b somename/short-descr-of-new-feature origin/somename/short-descr-of-new-feature
+
+1. Checkout a specific branch iff branch is already present locally:
+
+        % git checkout -b somename/short-descr-of-new-feature
+
+1. Adjust debian/changelog accordingly:
+
+        % gbp dch --debian-branch="$(git branch | awk -F\*\   '/^* / { print $2}' )" \
+          --since="v$(dpkg-parsechangelog | awk '/^Version:/ {print $2}')" -S --id-length=7 --meta --multimaint-merge
+
+1. Build package:
+
+        % gbp buildpackage --git-ignore-new --git-debian-branch="$(git branch | awk -F\*\  '/^* / { print $2}' )" --post-clean
+
+***
+
+### <a name="snapshot">3.4 Build snapshot version</a>
+
+1. Adjust debian/changelog accordingly:
+
+        % gbp dch --debian-branch="$(git branch | awk -F\*\   '/^* / { print $2}' )" \
+          --since="v$(dpkg-parsechangelog | awk '/^Version:/ {print $2}')" -S --id-length=7 --meta --multimaint-merge
+
+1. Build package:
+
+        % gbp buildpackage --git-debian-branch="$(git branch | awk -F\*\  '/^* / { print $2}' )" --post-clean [-us -uc]
+
+***
+
+## <a name="contribute">4. Contribute</a>
+
+1. Create patch:
+
+        % git format-patch -s -p origin/master
+
+1. Send patch file(s) to maintainers via mail (requires Debian package git-email):
+
+        % git send-email --to=initramfs-tools@packages.debian.org $PATCHFILE[S]
+
+1. The development mailinglists are [debian-kernel@lists.debian.org](mailto:debian-kernel@lists.debian.org)
+   and [initramfs@vger.kernel.org](mailto:initramfs@vger.kernel.org).
+   Discussion of features, bugs and patches are more than welcome on one
+   of these lists.
+
+***
+
+## <a name="release">5. Release new version</a>
+
+1. Creating changelog:
+
+        % gbp dch --debian-branch master --release --since HASH
+
+   or more dynamically:
+
+        % gbp dch --meta --release --since v$(dpkg-parsechangelog | awk '/^Version:/ {print $2}') --debian-branch="$(git branch | awk -F\*\  '/^* / { print $2}' )" --id-length=7 --meta --multimaint-merge
+
+   **NOTE:** we do not use history based sorting for the changelog entries but
+   sort them by author.
+
+1. Releasing:
+
+        % git commit -a -s -m "Releasing version $version."
+
+1. Tagging:
+
+        % git tag -s v"$version" -m "release $version"
+
+1. Pushing:
+
+        % git push
+        % git push --tags
+
+1. Build in chroot and upload to ftp-master.
+
+1. Send mail announcing the new initramfs-tools version with subject
+   "initramfs-tools $VERSION release" to initramfs@vger.kernel.org,
+   debian-kernel@lists.debian.org + kernel-team@lists.ubuntu.com - including a
+   shortlog (generated through "git shortlog $TAG..").
