Installing this on Linux is straightforward.

1. You need Pandoc. On Debian, Ubuntu, etc. this is: `sudo apt-get install pandoc`. I'm sure there's a similar incantation for Arch and so forth, but I can't be arsed. If you don't already have Ruby installed in your system, you'll need that too.

2. cd into your favorite personal toolbox directory and `git clone https://github.com/sinclairtarget/um.git`

3. Add a symlink to um in /usr/local/bin: `sudo ln -s /your/path/to/um/bin/um /usr/local/bin/um`. Make sure you're symlinking to the um script, not the um directory.

That's it. Enjoy.

Nice little widget. I like it.
