You can install Giter8 and other Scala command line tools with Conscript. This will setup Conscript in ~/.conscript/bin/cs:

curl | sh

(See Conscript's readme for a non-unixy option.) Once cs is on your path, you can install (or upgrade) giter8 with this command:

cs foundweekends/giter8

To make sure everything is working, try running g8 with no parameters. This should download giter8 and its dependencies, then print a usage message.

When it’s time to upgrade to a new version of giter8, just run the same cs command again.

Giter8 is also installable with the OS X package manager Homebrew:

$ brew update && brew install giter8
