# How to Contribute

## Identify an area to Contribute to​

There are several ways to identify an area where you can contribute to the Wiki:

• The easiest is to reach out to one of the Wiki maintainers  saying “I want to help contribute to the Polygon Wiki”. They’ll work with you to find an area for you to contribute.
• If you have a specific contribution in mind but are unsure about it, confirm whether the contribution is appropriate by contacting one of the Wiki maintainersdirectly.
• If you do not have a specific contribution in mind, you can also browse the issues labelled as help wanted on the Polygon GitHub repos.
• Issues that additionally have the good first issue label are considered ideal for first-timers.

## Add to the Polygon documentation​

If you are adding a new document, it is recommended to just have a basic summary/introduction and a link to your github or documentation for more details.

## Git rules​

We use gitchangelog for all of our repos for change logs. For that, we need to comply with the following convention for commit message. There will be no merge if you are not following this convention.

### Commit message convention​

The following are suggestions to what might be useful to think about adding in your commit messages. You might want to separate roughly your commits into big sections:

• by intent (for example: new, fix, change ...)
• by object (for example: doc, packaging, code ...)
• by audience (for example: dev, tester, users ...)

Additionally, you could want to tag some commits:

• As “minor” commits that shouldn’t get output to your changelog (cosmetic changes, small typo in comments...).
• As “refactor” if you don’t really have any significative feature changes. Thus this should not also be part of the changelog displayed to final user for instance, but might be of some interest if you have a developer changelog.
• You could tag also with “api” to mark API changes or if it's a new API or similar.

Try writing your commit message by targeting user functionality as often as you can.

Example

This is a standard git log --oneline to show how these information could be stored:

* 5a39f73 fix: encoding issues with non-ascii chars.* a60d77a new: pkg: added .travis.yml for automated tests. * 57129ba new: much greater performance on big repository by issuing only one shell command for all the commits. (fixes #7)* 6b4b267 chg: dev: refactored out the formatting characters from GIT.* 197b069 new: dev: reverse natural order to get reverse chronological order by default. !refactor * 6b891bc new: add utf-8 encoding declaration !minor
