== Setup ==
1. In an Admin PowerShell session, run `dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart`
2. If you want to use hardware virtualization stuff then also run `dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart` but honestly I've never yet once done this, especially since I'm often using Windows in a VM already and nesting gets . . . tricky.
3. Now (maybe after a restart) you should have the `wsl` command available to you. Get a list of distros with `wsl --online --list`
4. Install your distro of choice with `wsl --install -d distroname`

== Issues ==
Using something like `rsync` on the filesystem outside of WSL (ex. something on `/mnt/c`, where the `C:\` drive is automounted by default) will throw errors because the user doesn't have permissions to change some file properties. See https://github.com/microsoft/WSL/issues/3187#issuecomment-388904048, the lazy solution however is to just use `sudo` in those instances.
