bricks/ev3dev/README: Archive build notes.
Add some old build notes so we don't forget about them.
## Building
See the [docker](./docker) folder for build instructions.

+## Development tricks for Ubuntu
+
+The following tips can help speed up development on Ubuntu.
+
+Once connected, you can mount the robot file system locally for easy access:
+
+```
+gio mount ssh://robot@192.168.133.101/home/robot
+```
+
+Run the following on the brick once after preparing the microSD card.
+
+```
+rm -f pybricks-micropython
+touch pybricks-micropython
+chmod +x pybricks-micropython
+sudo rm -f /usr/bin/pybricks-micropython
+sudo ln -s /home/robot/pybricks-micropython /usr/bin/pybricks-micropython
+```
+
+Once you've followed the steps above, you can build and deploy using:
+
+```
+make ev3dev-armel && cp bricks/ev3dev/pybricks-micropython /run/user/1000/gvfs/sftp:host=*,user=robot/home/robot
+```
+
+Then all pybricks-micropython tools and projects will use the new build without
+requiring further modifications in the project.
+
+Start Pybricks and run commands to initialize it for easy testing:
+
+```
+brickrun --redirect -- pybricks-micropython -i -c "from core import *; print('add even more init here')"
+```
