 ## Install
 
+The simplest method of installation is using homebrew. You can also build from source.
 
-### homebrew
+### from homebrew
 
 vpngate can be installed with [homebrew](https://brew.sh/):
 
-```sh
+```shell
+# Ensure that Xcode is installed
+sudo xcode-select --install
+
+# OpenVPN is required
 brew install openvpn
+
 brew install davegallant/public/vpngate
 ```
 
-### source
+### from source
 
 Ensure that [go](https://golang.org/doc/install) is installed.
 
-```console
+```shell
-$ CGO_ENABLED=0 go get github.com/davegallant/vpngate
+CGO_ENABLED=0 go get github.com/davegallant/vpngate
 ```
 
 Ensure that the go bin path is discoverable:
 
-```console
+```shell
-$ echo 'export PATH=$PATH:$HOME/go/bin' >> ~/.profile
+echo 'export PATH=$PATH:$HOME/go/bin' >> ~/.profile
-$ source ~/.profile
+source ~/.profile
 ```
 
 ## Usage
 
 ### List available servers
 
-```console
+```shell
-$ vpngate list
+vpngate list
 ```
 
 ### Connect to a server
 
 On macOS, `openvpn` may not be within your PATH. To fix this, run:
 
-```console
+```shell
-$ export PATH=$(brew --prefix openvpn)/sbin:$PATH
+export PATH=$(brew --prefix openvpn)/sbin:$PATH
 ```
 
 The above command can also be added to a bash/zsh profile for future use.
 
 Because openvpn creates a network interface, run the connect command with `sudo` or a user with escalated privileges.
 
-```console
+```shell
-$ sudo vpngate connect
+sudo vpngate connect
 ```
 
 #### Random
 
 If the country doesn't matter, a random server can be selected:
 
-```console
+```shell
-$ sudo vpngate connect --random
+sudo vpngate connect --random
 ```
 
 #### Reconnect
 
 To continually attempt to reconnect (this can be combined with `--random`):
 
-```console
+```shell
-$ sudo vpngate connect --reconnect
+sudo vpngate connect --reconnect
 ```
