you need to add the froyo shell script to you .local/bin directory
cd froyo
cp froyo-home-directory/froyo ~/.local/bin
then i like to chmod the froyo file
chmod +x ~/.local/bin/froyo
you now need to create the froyo directory in /opt/ and move froyo.py there
sudo mkdir /opt/froyo
sudo cp froyo-home-directory/froyo.py /opt/froyo/
now when you run
froyo
alternatively you could just run the setup script
it should be all setup
if there is an issue (and there will be one) please open an issue
