MongoDB Cheat Sheet (v2.4)

For those MongoDB DBAs out there or students or whoever using MongoDB, Here's one thing you don't want to miss: a cheat sheet. It was created by Daniel Hodgin (http://www.hodgin.ca/). The cheat sheet is simple, readable, and covers about all of those basics you would want to do with your MongoDB (it was made based on version 2.4). He arranged, separated each section (sharding, db, etc) within each box, so you can easily understand which command runs on which level.
Here's the link to a copy of his cheat sheet (.pdf). Send any comments, suggestions, updates to his blog up there. :)

Note: I will update with a jpg version of the sheet as soon as I got home.

Edit: Here's the jpg version of the cheat sheet I promised :)
