- Not sure if that typo is worth a pull request? Do it! We will appreciate it.
- If your pull request is not accepted on the first try, don't be discouraged! We will do our best to give you feedback on what to improve.
- We're trying very hard to keep gocosmosdb lean and focused. We don't want it to do everything for everybody. This means that we might decide against incorporating a new feature. However, we encourage you to fork our repo and implement it on top of gocosmosdb.
- Any changes or improvements should be documented as a GitHub issue before we add it to the project and anybody starts working on it.
- Please check for existing issues first - If it does add a quick "+1". This will help prioritize the most common problems and requests.
