+## MySQL
+
+### Install
+
+We will install [MySQL](http://www.mysql.com/) using Homebrew, which will also install some header files needed for MySQL bindings in different programming languages (MySQL-Python for one).
+
+To install, run:
+
+    $ brew update # Always good to do
+    $ brew install mysql
+
+As you can see in the ouput from Homebrew, before we can use MySQL we first need to set it up with:
+
+    $ unset TMPDIR
+    $ mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
+
+### Usage
+
+To start the MySQL server, use the `mysql.server` tool:
+
+    $ mysql.server start
+    
+To stop it when you are done, run:
+
+    $ mysql.server stop
+    
+You can see the different commands available for `mysql.server` with:
+
+    $ mysql.server --help
+    
+To connect with the command-line client, run:
+
+    $ mysql -uroot
+    
+(Use `exit` to quit the MySQL shell.)
+
+**Note**: By default, the MySQL user `root` has no password. It doesn't really matter for a local development database. If you wish to change it though, you can use `$ mysqladmin -u root password 'new-password'`.
+
+### MySQL Workbench
+
+In terms of a GUI client for MySQL, I'm used to the official and free [MySQL Workbench](http://www.mysql.com/products/workbench/). But feel free to use whichever you prefer.
+
+You can find the MySQL Workbench download [here](http://www.mysql.com/downloads/workbench/). (**Note**: It will ask you to sign in, you don't need to, just click on "No thanks, just start my download!" at the bottom.)
 
 ## Projects folder
 
 This really depends on how you want to organize your files, but I like to put all my version-controlled projects in `~/Projects`. Other documents I may have, or things not yet under version control, I like to put in `~/Dropbox` (if you have Dropbox installed), or `~/Documents`.
