How can I learn to understand how Mercurial works as an experienced git user?

I have been using git for a while, and since this is the only DVCS I have ever used, I have learned to rely a lot on how it works for my workflow.

Now I am in a new company, and they use Mercurial, so I need to understand the Mercurial model and its difference from git, adapt my workflow and avoid costly mistakes.

So what resources can I use for this?
