+Contributing to Mongoid-Slug
+============================
+
+Mongoid-slug is work of [many of contributors](https://github.com/digitalplaywright/mongoid-slug/graphs/contributors). You're encouraged to submit [pull requests](https://github.com/digitalplaywright/mongoid-slug/pulls), [propose features, ask questions and discuss issues](https://github.com/digitalplaywright/mongoid-slug/issues).
+
+#### Fork the Project
+
+Fork the [project on Github](https://github.com/digitalplaywright/mongoid-slug) and check out your copy.
+
+```
+git clone https://github.com/contributor/mongoid-slug.git
+cd mongoid-slug
+git remote add upstream https://github.com/digitalplaywright/mongoid-slug.git
+```
+
+#### Create a Topic Branch
+
+Make sure your fork is up-to-date and create a topic branch for your feature or bug fix.
+
+```
+git checkout master
+git pull upstream master
+git checkout -b my-feature-branch
+```
+
+#### Bundle Install and Test
+
+Ensure that you can build the project and run tests.
+
+```
+bundle install
+bundle exec rake
+```
+
+#### Write Tests
+
+Try to write a test that reproduces the problem you're trying to fix or describes a feature that you want to build. Add to [spec/mongoid](spec/mongoid).
+
+We definitely appreciate pull requests that highlight or reproduce a problem, even without a fix.
+
+#### Write Code
+
+Implement your feature or bug fix.
+
+Ruby style is enforced with [Rubocop](https://github.com/bbatsov/rubocop), run `bundle exec rubocop` and fix any style issues highlighted.
+
+Make sure that `bundle exec rake` completes without errors.
+
+#### Write Documentation
+
+Document any external behavior in the [README](README.md).
+
+#### Update Changelog
+
+Add a line to [CHANGELOG](CHANGELOG.md) under *Next*. Make it look like every other line, including your name and link to your Github account.
+
+#### Commit Changes
+
+Make sure git knows your name and email address:
+
+```
+git config --global user.name "Your Name"
+git config --global user.email "contributor@example.com"
+```
+
+Writing good commit logs is important. A commit log should describe what changed and why.
+
+```
+git add ...
+git commit
+```
+
+#### Push
+
+```
+git push origin my-feature-branch
+```
+
+#### Make a Pull Request
+
+Go to https://github.com/contributor/mongoid-slug and select your feature branch. Click the 'Pull Request' button and fill out the form. Pull requests are usually reviewed within a few days.
+
+#### Rebase
+
+If you've been working on a change for a while, rebase with upstream/master.
+
+```
+git fetch upstream
+git rebase upstream/master
+git push origin my-feature-branch -f
+```
+
+#### Update CHANGELOG Again
+
+Update the [CHANGELOG](CHANGELOG.md) with the pull request number. A typical entry looks as follows.
+
+```
+* [#123](https://github.com/digitalplaywright/mongoid-slug/pull/123): Reticulated splines - [@contributor](https://github.com/contributor).
+```
+
+Amend your previous commit and force push the changes.
+
+```
+git commit --amend
+git push origin my-feature-branch -f
+```
+
+#### Check on Your Pull Request
+
+Go back to your pull request after a few minutes and see whether it passed muster with Travis-CI. Everything should look green, otherwise fix issues and amend your commit as described above.
+
+#### Be Patient
+
+It's likely that your change will not be merged and that the nitpicky maintainers will ask you to do more, or fix seemingly benign problems. Hang on there!
+
+#### Thank You
+
+Please do know that we really appreciate and value your time and work. We love you, really.
