Mechanig is currently under development, where there is not yet a stable version to launch it, so do not expect everything to be perfect in this tool, there are many problems, but you will get a day on some of the new reforms.
To install the beta version on Ubuntu Open the terminal and run the following commands :
sudo add-apt-repository ppa:freyja-dev/mechanig-daily
sudo apt-get update
sudo apt-get install mechanig
