+# Contributing
+
+## Setup
+
+You should have [node.js], [npm] and [gulp] installed.
+
+## Linting
+
+Linting is done using [eslint] and the rules are based on [standard]
+
+```bash
+$ gulp lint
+```
+
+## Tests
+
+Tests in node
+
+```bash
+$ gulp test:node
+```
+
+Tests in the browser
+
+```bash
+$ gulp test:browser
+```
+
+## Building browser version
+
+```bash
+$ gulp build
+```
+
+## Releases
+
+The `release` task will
+
+1. Run a build
+2. Commit the build
+3. Bump the version in `package.json`
+4. Commit the version change
+5. Create a git tag
+6. Run `git push` to `upstream/master` (You can change this with `--remote my-remote`)
+
+```bash
+# Major release
+$ gulp release --major
+# Minor relase
+$ gulp release --minor
+# Patch release
+$ gulp release
+```
