+    Set up databases to run AS YOUR USER ACCOUNT with:
+        unset TMPDIR
+        mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
+
+    To set up base tables in another folder, or use a differnet user to run
+    mysqld, view the help for mysqld_install_db:
+        mysql_install_db --help
+
+    and view the MySQL documentation:
+      * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html
+      * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html
+
+    To run as, for instance, user "mysql", you may need to `sudo`:
+        sudo mysql_install_db ...options...
+
+    Start mysqld manually with:
+        mysql.server start
+
+    A "/etc/my.cnf" from another install may interfere with a Homebrew-built
+    server starting up correctly.
+
+    To connect:
+        mysql -uroot
+
+    To launch on startup:
+    * if this is your first install:
+        mkdir -p ~/Library/LaunchAgents
+        cp /usr/local/Cellar/mysql/5.5.10/com.mysql.mysqld.plist ~/Library/LaunchAgents/
+        launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
+
+    * if this is an upgrade and you already have the com.mysql.mysqld.plist loaded:
+        launchctl unload -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
+        cp /usr/local/Cellar/mysql/5.5.10/com.mysql.mysqld.plist ~/Library/LaunchAgents/
+        launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
+
+    You may also need to edit the plist to use the correct "UserName".
