Installing barge

git clone https://github.com/paragonie/airship-barge.git
cd airship-barge
sudo ln -s ./barge /usr/bin/barge

To install barge, first clone the Github repository, then create a symlink from /usr/bin/barge to the barge file in the project's root directory.

Alternatively, you could create a shell function (e.g. in your .bashrc file).

When a new version of barge is released, just cd into the airship-barge directory and run git pull origin master.
