# Contribution guidelines

Welcome to the 🐸TTS!

This repository is governed by the Contributor Covenant Code of Conduct - [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md).

## Where to start.
We welcome everyone who likes to contribute to 🐸TTS.
You can contribute not only with code but with bug reports, comments, questions, answers, or just a simple tweet to spread the word.

If you like to contribute code, squash a bug but if you don't know where to start, here are some pointers.

- [Github Issues Tracker](https://github.com/coqui-ai/TTS/issues)

    This is a place to find feature requests, bugs.

    Threads with the ```good first issue``` tags are a good place to start for beginners.

- The next version's ✨**PR**✨ [page](https://github.com/coqui-ai/TTS/pulls) with the ```🚀new version``` tag.

    We list all the improvements we like to target for the next version there. You can pick one of these and start to work on it with us.

- Also feel free to suggest new features, ideas and models.
## Sending a ✨**PR**✨

If you have a new feature, a model to implement, or a bug to squash, go ahead and send a ✨**PR**✨.
Please use the following steps to send a ✨**PR**✨.
Let us know if you encounter a problem along the way.

The following steps are tested on an Ubuntu system.

1. Fork 🐸TTS[https://github.com/coqui-ai/TTS] by clicking the fork button at the top right corner of the project page.

2. Clone 🐸TTS and add the main repo as a new remote named ```upsteam```.

    ```bash
    $ git clone git@github.com:<your Github name>/TTS.git
    $ cd TTS
    $ git remote add upstream https://github.com/coqui-ai/TTS.git
    ```

3. Install 🐸TTS for development.

    ```bash
    $ make system-deps  # intended to be used on Ubuntu (Debian). Let us know if you have a different OS.
    $ make install
    ```

4. Create a new branch with an informative name for your goal.

    ```bash
    $ git checkout -b an_informative_name_for_my_branch
    ```

5. Implement your changes on your new branch.

6. Explain your code using [Google Style](https://google.github.io/styleguide/pyguide.html#381-docstrings) docstrings.

7. Add your tests to our test suite under ```tests```  folder. It is important to show that your code works, edge cases are considered, and inform others about the intended use.

8. Run the tests to see how your updates work with the rest of the project. You can repeat this step multiple times as you implement your changes to make sure you are on the right direction.

    ```bash
    $ make tests
    ```

9. Format your code. We use ```black``` for code and ```isort``` for ```import``` formatting.

    ```bash
    $ make style
    ```

10. Run the linter and correct the issues raised. We use ```pylint``` for linting.  It helps to enforce a coding standard, offers simple refactoring suggestions.

    ```bash
    $ make lint
    ```

11. When things are good, add new files and commit your changes.

    ```bash
    $ git add my_file1.py my_file2.py ...
    $ git commit
    ```

    It's a good practice to regularly sync your local copy of the project with the upstream code to keep up with the recent updates.

    ```bash
    $ git fetch upstream
    $ git rebase upstream/master
    # or for the development version
    $ git rebase upstream/dev
    ```

12. Send a PR to ```dev``` branch.

    Push your branch to your fork.

    ```bash
    $ git push -u origin an_informative_name_for_my_branch
    ```

    Then go to your fork's Github page and click on 'Pull request' to send your ✨**PR**✨.

    Please set ✨**PR**✨'s target branch to ```dev``` as we use ```dev``` to work on the next version.

13. Let's discuss until it is perfect. 💪

    We might ask you for certain changes that would appear in the ✨**PR**✨'s page under 🐸TTS[https://github.com/coqui-ai/TTS/pulls].

14. Once things look perfect, We merge it to the ```dev``` branch and make it ready for the next version.

Feel free to ping us at any step you need help using our communication channels.
