+# Maintainer Guidelines
+
+These are guidelines for maintainers of this repository as (mostly) [gifted to us by](https://github.com/ReactiveX/RxJS/issues/121#issue-97747542)
+His Beardliness, @jeffbcross. They are words to live by for those that are tasked with reviewing and merging pull requests and otherwise
+shepherding the community. As the roster of trusted maintainers grows, we'll expect these guidelines to stay pretty
+much the same (but suggestions are always welcome).
+
+
+### The ~~10~~ 6 Commandments
+
+ * __[Code of Conduct](../CODE_OF_CONDUCT.md)__. We should be setting a good example and be welcoming to all. We should be listening
+ to all feedback from everyone in our community and respect their viewpoints and opinions.
+ * __Be sure PRs meet [Contribution Guidelines](../CONTRIBUTION.md)__. It's important we keep our code base 
+ and repository consistent. The best way to do this is to know and enforce the contribution guidelines.
+ * __Clean, flat commit history__. We never click the green merge button on PRs, but instead we pull down 
+ the PR branch and rebase it against master then replace master with the PR branch. See 
+ [example gist](https://gist.github.com/jeffbcross/307c6da45d26e29030ef). This reduces noise in the commit 
+ history, removing all of the merge commits, and keeps history flat. The flat history is beneficial 
+ to tools/scripts that analyze commit ancestry.
+ * __Always green master__. Failing master builds tend to cascade into other broken builds, and 
+ frustration among other contributors who have rebased against a broken master. Much of our deployment 
+ and other infrastructure is based on the assumption that master is always green, nothing should be
+ merged before Travis has confirmed that a PR is green, even for seemingly insignificant changes. 
+ Nothing should be merged into a red master, and whomever broke it should drop everything and fix it 
+ right away. Fixes should be submitted as a PR and verified as green instead of immediately merging 
+ to master.
+ * __No force pushes to master__. Only in rare circumstances should a force push to master be made, 
+ and other maintainers should be notified beforehand. The most common situation for a justified force 
+ push is when a commit has been pushed with an invalid message. The force push should be made as soon 
+ as possible to reduce side effects.
+ * __Small, logical commits__. A PR should be focused on a single problem, though that problem may be
+ reasonable to be broken into a few logical commits. For example, a global renaming may be best to be 
+ broken into a single commit that renames all files, and then a commit that renames symbols within files. 
+ This makes the review process simpler easier, so the diff of the meaty commit (where symbols are 
+ renamed) can be easily understood than if both were done in the same commit, in which case github would 
+ just show a deleted file and an added file.
