+# Setting up MySQL
+
+## OS X
+
+### Option 1 - Homebrew
+
+1. First, make sure you have homebrew installed
+2. Run `brew doctor` and address anything homebrew wants you to fix
+3. Run `brew install mysql`
+4. Run `brew services restart mysql`
+5. Run `mysql.server start`
+6. Run `mysql_secure_installation`
+
+## Windows
+
+1. Grab the [the appropriate windows installer](https://www.postgresql.org/download/windows/) and run it.
+2. Put the DLLs in your `C:\WINDOWS\system32` folder
+
+## Linux
+
+Use `apt-get` or equivalent.
+
+
+## All
+
+Once you've installed mysql, you can test your installation with a user of your choice (we'll use the `root` user) by running
+```sh
+mysqlshow -uroot -p
+```
+
+Finally, you'll need to create a login config file with the database's master username and password. Replace `root` with the master user account for your database if necessary
+
+```sh
+mysql_config_editor set --login-path=local --host=localhost --user=root --password
+```
+
+You should now be able to run
+```sh
+mysqlshow --login-path=local
+```
+without having to provide a password in the CLI.
