 ## About
 
 EMBD is affectionately designed/developed by Karan Misra ([kidoman](https://github.com/kidoman)), Kunal Powar ([kunalpowar](https://github.com/kunalpowar)) and [FRIENDS](https://github.com/cfreeman/embd/blob/master/AUTHORS). We also have a list of [CONTRIBUTORS](https://github.com/cfreeman/embd/blob/master/CONTRIBUTORS).
+
+## TODO
+* Continue to tidy up the readme and other documenting files.
+* Find more details/datasheet on the implemented watersensor.
+* Dig through logs and add license/copyright headers throughout.
+* Remove AUTHORS & CONTRIBUTORS -- That stuff is better maintained within git history (don't forget update_contributors script).
+* Make sure there are samples for all the supported hardware.
+* Organise samples into different folders.
+* Rummage through the old, largely abandoned parent repo and pull in as many of the requests as possible.

-# embd roadmap
-
-The following features are planned (in no particular order):
-
-* A fully featured cli tool (**embd**)
-* Support for UART, SPI
-* Support for a whole range of sensors/controllers
-* Support for Intel Galileo (will require a few changes to Golang, but not unsurmountable)
-* Support for a lot of other ARM prototyping boards (Cubietruck, Radxa, etc.)
-* Awesome documentation
-* A embd UI (similar to the Arduino IDE)
-* Supporting something other than Linux
-* Support for vision processing (OpenCV ?)
-* Allow remote instrumentation of the host via network/web sockets/etc.
