+## Releases
+If you are a collaborator, when you want release a new version, follow these steps.
+
+1. Make sure all the changes are merged into master
+2. Make sure all changes have passed [Travis CI build][1]
+3. Determine type of release. We use [Semantic Versioning](http://semver.org/).
+4. Update [CHANGELOG.md](CHANGELOG.md) with release notes and commit
+5. Run `npm version` command to increment `package.json` version, commit changes, tag changes, and push to upstream.
+    - Patch -> `npm version patch`
+    - Minor -> `npm version minor`
+    - Major -> `npm version major`
+6. Once [Travis CI build][1] (from tag) has completed, make sure you're working directory is clean and run `npm publish`
+   while in the project root.
+7. Create a new [Github Release](https://github.com/SparkPost/node-sparkpost/releases) using the new tag. Copy release
+   notes from the [CHANGELOG.md](CHANGELOG.md).

 ## Development
 
 ### Setup
-We use [Grunt](http://gruntjs.com/) for our task runner, so you will also have to install Grunt globally `npm install -g grunt-cli`
-
 Run `npm install` inside the repository to install all the dev dependencies.
 
 ### Testing
-Once all the dependencies are installed, you can execute the unit tests using `grunt test`
