+There's no out of the box support for Windows CMD when it comes to custom prompts.
+There is however a way to do it using [Clink][clink], which at the same time supercharges
+your cmd experience. Follow the installation instructions and make sure you select autostart.
+
+Integrating Oh my Posh with Clink is easy: create a new file called oh-my-posh.lua in your Clink
+scripts directory (run `clink info` inside cmd to find that file's location).
