+## Submitting a pull request
 
-**Footnote:** tldr is under MIT license.
+TL;DR: fork, `make setup`, feature branch, commit, push, pull request.
+
+Detailed explanation:
+
+1. [Fork](http://help.github.com/fork-a-repo/) the project, clone your fork,
+   and configure the remotes:
+
+   ```bash
+   # Clone your fork of the repo into the current directory
+   git clone https://github.com/<your-username>/tldr
+   # Navigate to the newly cloned directory
+   cd tldr
+   # Assign the original repo to a remote called "upstream"
+   git remote add upstream https://github.com/tldr-pages/tldr
+   ```
+
+2. Setup Ruby, Rubygems, bundler, Git pre-commit hooks with Markdown linter.
+
+   ```bash
+   # Assuming Ruby is set up
+   # Install bundler Ruby gem
+   gem install bundler
+   make setup
+   ```
+
+3. If you cloned a while ago, get the latest changes from upstream:
+
+   ```bash
+   git checkout master
+   git pull upstream master
+   ```
+
+4. Create a new topic branch (sometimes they are called feature branches) off
+   the main project development branch:
+
+   ```bash
+   git checkout -b <topic-branch-name>
+   ```
+
+5. Run `make lint` to check that your page(s) are correct.
+
+6. Please use the following commit message format: 
+   `<command>: type of change`.
+
+   Examples:
+
+   - `ls: add page`
+   - `cat: fix typo`
+   - `git-push: add --force example`
+   - `uname: fix -a example`
+
+7. Push your topic branch up to your fork:
+
+   ```bash
+   git push origin <topic-branch-name>
+   ```
+
+8. [Open a Pull Request](https://help.github.com/articles/using-pull-requests/)
+    with a clear title and description.
+
+9. Use Git's
+   [interactive rebase](https://help.github.com/articles/interactive-rebase)
+   feature to tidy up your commits before making them public.
+   In most cases it is better to squash commits before submitting a pull request.
+
+10. If you are asked to amend your changes before they can be merged in, please
+   use `git commit --amend` and force push to your remote feature branch.
+   You may also be asked to squash commits.
+

+## Licensing

+`tldr` is under [MIT license](https://github.com/tldr-pages/tldr/blob/master/LICENSE.md).
+
+**IMPORTANT**: By submitting a patch, you agree to license your work under the
+same license as that used by the project.
 
 You're free to modify or redistribute the content. That being said, but why not contribute over here? :) Say if you wanted to have `tldr` pages in `groff` format, why not have a client that uses [pandoc](http://johnmacfarlane.net/pandoc/) and periodically updates straight from this repo?
