-A GitHub Action for installing, configuring and running Android Emulators on macOS virtual machines.
+A GitHub Action for installing, configuring and running hardware-accelerated Android Emulators on macOS virtual machines.
 
 The old ARM-based emulators were slow and are no longer supported by Google. The modern Intel Atom (x86 and x86_64) emulators require hardware acceleration (HAXM on Mac & Windows, QEMU on Linux) from the host to run fast. This presents a challenge on CI as to be able to run hardware accelerated emulators within a docker container, **KVM** must be supported by the host VM which isn't the case for cloud-based CI providers due to infrastructural limits. If you want to learn more about this, here's an article I wrote: [Running Android Instrumented Tests on CI](https://dev.to/ychescale9/running-android-emulators-on-ci-from-bitrise-io-to-github-actions-3j76).

+## Can I use this action on Linux VMs?
+
+The short answer is yes but it's expected to be a much worse experience (on some newer API levels it might not work at all) than running it on macOS.
