%h3 Submitting a pull request

%p All development happens via pull requests. To add a new feature or fix a bug, the developer must create a new branch off <code>develop</code>, make their changes, and then issue a pull request for another developer to review before the changes get merged back into <code>develop</code>.

%p Here is an example, using github with username <code>rms</code> and repository <code>bitmask_client</code>. You don't need to use github, but it is a friendly way to get started.

%p
  %b Step 1 &mdash; Fork on github

%p Login to github.com as 'rms', browse to #{link 'https://github.com/leapcode/bitmask_client'}, and click the fork button.

%p Now you should have a fork of the code available at <code>https://github.com/rms/bitmask_client</code>.

%p
  %b Step 2 &mdash; Set up local clone

%p Clone the upstream repository:

%pre
  %code
    git clone https://leap.se/git/bitmask_client
    cd bitmask_client

%blockquote
  .p NOTE: Alternately, you can use the github mirror at <code>https://github.com/leapcode/bitmask_client</code>. It does not matter which one you choose.

%p
  %b Step 4 &mdash; Add a "remote" for your fork

%p Next, you need to add the fork you created on github as an alternate remote in your local repository:

%pre
  %code
    git remote add rms https://github.com/rms/bitmask_client.git

%p
  %b Step 5 &mdash; Create a new feature branch

%pre
  %code
    git fetch origin
    git checkout develop
    git checkout -b feature/my_new_feature

%p
  %b Step 6 &mdash; Hack away

%P Make all your changes in your <code>feature/my_new_feature</code> branch, with a separate <code>git commit</code> for each discrete modification you make.

%p
  %b Step 7 &mdash; Prepare for pull request

%p Once you are happy with your branch, prepare it for a pull request by rebasing on the latest upstream <code>develop</code> branch. This will also give you an opportunity to clean up your commit history by squashing and changing commit messages.

%pre
  %code
    git fetch origin                    # ensure the latest
    git checkout feature/my_new_feature # if not already checked out
    git rebase -i develop               # rebase and clean up commits

%p
  %b Step 8 &mdash; Submit pull request

%p Next, you will push your local feature branch to your fork on github, and then issue a pull request.

%pre
  %code
    git push rms feature/my_new_feature

%p Then browse to <code>https://github.com/rms/bitmask_client</code>, where you will see a handy button to issue a pull request. Make sure that the upstream branch is <code>leapcode/bitmask_client:develop</code> and you are requesting the merge of <code>rms/bitmask_client:feature/my_new_feature</code>.

Then you are done. Some other developer will get a notice of your pull request, review the changes, and merge into upstream <code>develop</code> branch. If they have questions or comments, you will get an email from github.
