+Added an option to configure the path separator. If you want something
+else than an ordinary slash, you could set
+`POWERLEVEL9K_DIR_PATH_SEPARATOR` to whatever you want.

 a prompt segment. As an example, if you wanted to create a custom segment to
 display your WiFi signal strength, you might define a custom segment called
 `custom_wifi_signal` like this:
-
-    POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context time battery dir vcs virtualenv custom_wifi_signal)

 If you prefer, you can also define the function in your `.zshrc` rather than
 putting it in-line with the variable export, as shown above. Just don't forget
 to invoke your function from your segment! Example code that achieves the same
 result as the above:
+```zsh
