-Contributing to QGIS
-====================
-
-QGIS is an open source project and we appreciate contributions very much.
-
-Proper formatting
------------------
-
-Before making a pull request, please make sure your code is properly formatted
-by running the prepare commit script **before** issuing `git commit`.
-
-    ./scripts/prepare_commit.sh
-
-This can be automated by adding it to a pre-commit hook, for example:
-
-    pushd $(git rev-parse --git-common-dir)/hooks
-    test -e pre-commit && mv pre-commit pre-commit.000
-    echo '$(git rev-parse --show-toplevel)/scripts/prepare_commit.sh' > pre-commit
-    chmod +x pre-commit
-    popd
-
-Getting your pull request merged
---------------------------------
-
-This is a volunteer project, so sometimes it may take a little while to merge
-your pull request.
-
-There is a [guide with hints for getting your pull requests merged](https://docs.qgis.org/testing/en/docs/developers_guide/git.html#pull-requests)
-in the developers guide.
