To download the very latest SLIME you first configure
GitROOT and login to the repository.
git clone https://github.com/slime/slime.git
You might substitute
http if you're having
problems with that protocol.
If you want to find out what's new since the version you're currently running, you can diff the local ChangeLog against the repository version:
git fetch origin git diff HEAD origin/master ChangeLog
If you want to hack on SLIME, use Github's fork functionality and submit a pull request. Be sure to first read the CONTRIBUTING.md file first.
