RELEASING.md

+# Releasing
+
+There're no particular rules about when to release ruby-grape-danger. Release bug fixes frequenty, features not so frequently and breaking API changes rarely.
+
+### Release
+
+Run tests, check that all tests succeed locally.
+
+```
+bundle install
+rake
+```
+
+Check that the last build succeeded in [Travis CI](https://travis-ci.org/ruby-grape/ruby-grape-danger) for all supported platforms.
+
+Increment the version, modify [lib/ruby-grape-danger/version.rb](lib/ruby-grape-danger/version.rb).
+
+*  Increment the third number if the release has bug fixes and/or very minor features, only (eg. change `0.7.1` to `0.7.2`).
+*  Increment the second number if the release contains major features or breaking API changes (eg. change `0.7.1` to `0.8.0`).
+
+Change "Next Release" in [CHANGELOG.md](CHANGELOG.md) to the new version.
+
+```
+### 0.7.2 (February 6, 2014)
+```
+
+Remove the line with "Your contribution here.", since there will be no more contributions to this release.
+
+Commit your changes.
+
+```
+git add CHANGELOG.md lib/ruby-grape-danger/version.rb
+git commit -m "Preparing for release, 0.7.2."
+git push origin master
+```
+
+Release.

+
+### Prepare for the Next Version
