Instructions don't work as is on Windows

[dthaler]

The Readme file does not say this can only be done on Linux, and enclaves are OS-agnostic.
Please either add the equivalent steps for Windows, or state how to install the prerequisites so the commands work as listed.

Currently, apkman is Linux only. It relies on Linux features (e.g unshare, mount, chroot etc) to run an Alpine Linux distribution to fetch packages from.

It looks possible to provide an equivalent experience on Windows too. WSL can be used to run an Alpine Linux distribution on Windows; powershell can be used to script the management of this distribution.

While apkman is being published, in the interim, we can direct users to fetch prebuilt packages directly from the Alpine Repository: https://dl-cdn.alpinelinux.org/alpine/v3.12/main. Packages are available for x86_64 and aarch64.
7zip can be used to extract contents of Alpine Linux packages - .apk files.
