 ## Testing redux
 
-Before sending code out for review, run all the tests for the whole tree to make sure the changes don't break other usage and keep the compatibility on upgrade. To make sure you are running the test suite exactly like we do you should install the CLI for [Drone CI](https://github.com/drone/drone) as we are using the server for continous testing, follow [these instructions](http://readme.drone.io/0.5/install/cli/). After that you can simply call `drone exec` within you working directory and it will try to run the test suite locally.

 ## Code review
 
-Changes to Gitea must be reviewed before they are accepted, no matter who makes the change even if an owner or a maintainer. We use GitHub's pull request workflow to do that and we also use [LGTM](http://lgtm.co) to ensure every PR is reviewed by at least 2 maintainers.

+Please try to make your pull request easy to review for us. Please read the "[How to get faster PR reviews](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/faster_reviews.md)" guide, it has lots of useful tips for any project you may want to contribute. Some of the key points:
 
 * Make small pull requests. The smaller, the faster to review and the more likely it will be merged soon.
-* Don't make changes unrelated to your PR. Maybe there are typos on some comments, maybe refactoring would welcome on a function... but if that is not related to you PR, please make *another* PR for that.
-* Split big pull requests in multiple. An incremental change will be faster to review than a huge PR.

 ## Maintainers
 
-To make sure every PR have been checked, we got team maintainers. Any PR MUST be reviewed and by at least two maintainers before it can get merged. Maintainers should be a contributor of Gitea (or Gogs) and contributed at least 4 accepted PRs. A contributor should apply as a maintainer in [Gitter development channel](https://gitter.im/go-gitea/develop). The owners or the team maintainers could invite the contributor. A maintainer should spend some time on code reviews. If some maintainer have no time to do that, he should apply to leave the maintainers team and we will give him an honor to be as a member of advisor team. Of course, if an advisor have time to code view, welcome it back to maintainers team. If someone have no time to code review and forget to leave the maintainers team, the owners have the power to move him from maintainers team to advisors team.

 ## Owners
 
-Since Gitea is a pure community organization without any company support, to keep the development healthly we will elect the owners every year. Every time we will elect three owners. All the contributers could vote for three owners, one is the main owner, the other two are assistant owners. When the new owners have been elected, the old owners MUST move the power to the new owners. If some owner don't obey these rules, the other owners are allowed to revoke his owner status.
