 Next, the install script will perform a check to see if it is running on an OSX machine. If so, it will install Homebrew if it is not currently installed and will install the homebrew packages listed in [`brew.sh`](install/brew.sh). Then, it will run [`osx.sh`](install/osx.sh) and change some OSX configurations. This file is pretty well documented and so it is advised that you __read through and comment out any changes you do not want__. Next, nginx (installed from Homebrew) will be configured with the provided configuration file. If a `nginx.conf` file already exists in `/usr/local/etc`, a backup will be made at `/usr/local/etc/nginx/nginx.conf.original`.
 
+## Terminal Capabilities
+
+In order to properly support italic fonts in and out of tmux, a couple of terminal capabilities need to be described. Run the following from the root of the project:
+
+```bash
+tic -x resources/xterm-256color-italic.terminfo
+tic -x resources/tmux.terminfo
+```

 ## ZSH Setup
 
 ZSH is configured in the `zshrc.symlink` file, which will be symlinked to the home directory. The following occurs in this file:
