+## This is how are pull requests handled by FreeRDP
+1. Every new pull request needs to build and pass the unit tests at https://ci.freerdp.com
+1. At least 1 (better two) people need to review and test a pull request and agree to accept
+
+## Preparations before creating a pull
+* Rebase your branch to current master, no merges allowed!
+* Try to clean up your commit history, group changes to commits
+* Check your formatting! A _clang-format_ script can be found at ```.clang-format```
+  * The cmake target ```clangformat``` reformats the whole codebase
+* Optional (but higly recommended)
+  * Run a clang scanbuild before and after your changes to avoid introducing new bugs
+  * Run your compiler at pedantic level to check for new warnings
+
+## To ease accepting your contribution
+* Give the pull request a proper name so people looking at it have an basic idea what it is for
+* Add at least a brief description what it does (or should do :) and what it's good for
+* Give instructions on how to test your changes
+* Ideally add unit tests if adding new features
+
+## What you should be prepared for
+* fix issues found during the review phase
+* Joining IRC _#freerdp_ to talk to other developers or help them test your pull might accelerate acceptance
+* Joining our mailing list <freerdp-devel@lists.sourceforge.net> may be helpful too.
