+## Install dblib & FreeTDS on OS X
 
-Make sure your freetds config (usually located in /etc/freetds/freetds.conf) contains this block:
+The simplest way to install dblib on OS X is by using [Homebrew](http://brew.sh/). This guide will therefore assume that you have [Homebew installed](http://brew.sh/), are using PHP [installed with Homebrew](https://github.com/Homebrew/homebrew-php#installation) and using the native Apache server in OS X.
+
+### Install
+
+1. `brew update`
+2. `brew install php56-pdo-dblib` The installation can take some time, be patient!
+3. `sudo apachectl restart`
+
+*Any version of PHP installed with Homebrew should work. Just change `php56` in the command to your version.*
+
+### Update the FreeTDS config
+
+To finish up we also need to do some light modifications to the FreeTDS configuration.
+
+You should find the config file in `/usr/local/etc/freetds.conf`. Open it with your favorit text editor.
+
+In the `[global]` section, find a line that looks like
+
+```
+# TDS protocol version
+; tds version = x
+```
+
+Uncomment the line and change the version number to **8**, you should have
+
+```
+# TDS protocol version
+tds version = 8
+```
+
+And finally, add the following line below the version
+
+```
+# Charset
+client charset = UTF-8
+```
 
+Save the changes and you are good to go.
