+Hints for this version
+----------
+
+* Fork of https://github.com/miguelbalboa/rfid/
+* Changed license to GNU LESSER GENERAL PUBLIC LICENSE, Version 2.1.
+* Target group are experienced makers.
+* Code was heavily split up for better maintenance.
+* Hardware interface is fully customisable.
+* Use of software reset. No reset pin.
+* Some parts were removed.

 Development
 ----------
 
-**The development by owner miguelbalboa has ended**.
-
-**Feature status: complete freeze**; no function or API change.
+**Feature status: open**; focus on rfid; no applications;
 
-**Code status: partial freeze**; just fixes/typos or documentation updates; *no* extensions for other boards; *no* new examples.
-
-**Maintenance status: sporadically**.
-
-**Why no further development?**
-This library has a long history and is used in many projects. These projects often do not document what version they use. Committing changes might break those old projects and lead to bad experiences (for beginners) and support requests. For these reasons the library is in freeze mode. You can still commit typo, documentation or bug fixes.
+**Code status: open**; fixes/typos or documentation updates; *no* specific code for other boards; *avoid* examples;
