+# Releasing Grape::ActiveModelSerializers
+
+There're no particular rules about when to release grape-active_model_serializers. Release bug fixes frequently, 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/grape-active_model_serializers) for all supported platforms.
+
+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/grape-active_model_serializers/version.rb
+git commit -m "Preparing for release, 0.7.2."
+git push origin master
+```
+
+Release.
+
+```
+$ rake release

+Tagged v0.7.2.
+Pushed git commits and tags.
+Pushed grape-active_model_serializers 0.7.2 to rubygems.org.
+```
+
+### Prepare for the Next Version
+
+Modify [lib/grape-active_model_serializers/version.rb](lib/grape-active_model_serializers/version.rb), increment the third number (eg. change `0.7.2` to `0.7.3`).
+
+
+```ruby
+module Grape
+  module ActiveModelSerializers
+    VERSION = '0.7.3'.freeze
+  end
+end
+```
+
+Add the next release to [CHANGELOG.md](CHANGELOG.md).
+
+```
+#### 0.7.3 (Next)
