Paper Plane is an Open Source Project

You Should Know

To contribute with a small fix, simply create a pull request.
Better to open an issue to discuss with the team and the community if you're intended to work on something BIG (Wellcome to join our Slack Group Android Devs, email me first and then I will invite you as soon as possible).

Search previous suggestions before making a new one, as yours may be a duplicate.
Make an individual pull request for each suggestion.
Titles should be capitalized.
Keep descriptions short and simple.
End all descriptions with a full stop/period.
Check your spelling and grammar.
Make sure your text editor is set to remove trailing whitespace.
Try to make your Pull request and title as descriptive as possible.

Check out our wiki to see more information about this project.
Better to use English to open issues and pull requests.
