 # WebVM
 
-This repository hosts the source code of the [https://webvm.io](https://webvm.io) live demo page.
+This repository hosts the source code of for [https://webvm.io](https://webvm.io), a Linux virtual machine that runs in your browser.
 
-WebVM is a server-less virtual environment running fully client-side in HTML5/WebAssembly. It's designed to be Linux ABI-compatible. In this demo, it runs an unmodified Debian distribution including many native development toolchains.
+WebVM is a server-less virtual environment running fully client-side in HTML5/WebAssembly. It's designed to be Linux ABI-compatible. It runs an unmodified Debian distribution including many native development toolchains.
 
 WebVM is powered by the CheerpX virtualization engine, and enables safe, sandboxed client-side execution of x86 binaries on any browser. CheerpX includes an x86-to-WebAssembly JIT compiler, a virtual block-based file system, and a Linux syscall emulator.

+# How to: general usage
 
-# Enable Networking
+- go to [https://webvm.io](https://webvm.io)
+- use the provided terminal environment
+- have fun!
 
-- Click "Tailscale Login" in the top right corner.
-- Log in to Tailscale (create an accout if you don't have one)
-- If you want to access the public internet, you need an Exit Node. See here for how to set one up. If you just want to access a machine in your Tailscale Network, you don't need it.
-- Depending on your network speed, you may need to wait a few moments for the Tailscale Wasm module to be downloaded.
-- Log in with your Tailscale credentials.
-- Go back to the WebVM tab. You will see your IP address in the top right.
-- Start firing network requests!

 Given the short-lived nature of WebVM, we log into Tailscale as an Ephemeral Node. This means that the node will disappear from your Tailscale Network after a period of inactivity. It also means that when you reload the tab, you need to log in again. It should be faster the second time.
