[PATCH] Added git ignore for pycharm project dir
by pgagne＠redhat.com 13 May '20

13 May '20

From: Perry Gagne <pgagne(a)redhat.com> I know some of use use pycharm, so I wasn't sure if this annoyed other people but pycharm creates this directory to store all its settings. We probably want to ignore it, so it doesn't show up anymore. Thought I suggest a patch to do it.

Documentation available on readthedocs

04 May '20

Hi all, after a little bit of tinkering and pushing several small patches I managed to get the documentation get hosted on readthedocs.org: https://lnst.readthedocs.io/en/latest/ This will get automatically updated every time we push new commits on top of the master branch, but you may need to Ctrl+F5 sometimes to hard refresh the changed pages to refresh whatever is cached. Feel free to report any issues/improvements for the documentation, we know it's far from perfect and not complete yet and we'll continue working on it. -Ondrej
