+### Open Development Process
+
+This project is completely managed here on GitHub using its [issue tracker](https://github.com/objectbox/objectbox-dart/issues) and [project boards](https://github.com/objectbox/objectbox-dart/projects).
+
+To prepare an upcoming version, we create a (Kanban like) board for it.
+Once it is decided which features and fixes go into the version, the according issues are added to the board.
+Issues on the board are referred to as "cards" which move from left to right:
+
+* New cards start in the "To Do" column.
+  Within the column, cards are ordered: more important tasks should be above less important ones.  
+* Once somebody starts on a task, the according card is moved to "In progress".
+  Also, please assign yourself to the issue.
+* Once a task is considered complete (e.g. PR is made), put it in the "Review" column.
+* Once another person had a look and is happy, the task is finally moved to "Done"
+ 
+Anyone can contribute in this process. Look for tasks having a **"help wanted"** tag.
+
+### Feedback
+
 Also, please let us know your feedback by opening an issue:
 for example, if you experience errors or if you have ideas for how to improve the API.
 Thanks!

 Internally, ObjectBox uses [FlatBuffers](https://google.github.io/flatbuffers/) to store objects.
 There are two basic ways to make the conversion: generated binding code, or implicit FlatBuffers conversion.
-In order to require as little setup as possible and to define entity classes directly in Dart code, the latter is used in this binding.
