 An EteSync web client. Use EteSync from the browser
 
-# Status
+# Usage
 
-This project is not ready just yet, but it'll hopefully be soon.
+**Note:** This is still in an early stage. It should perfectly safe to use (though
+plase refer to the warning at the bottom) but you should expect bugs/bad design.
 
-After it's ready you'll be able to run it locally and just use a full EteSync
+A live isntance is available on: https://client.etesync.com
-client from the browser!
 
-We will also have a hosted version of this, but it's not as secure as running
+Please be advised that while it's probably safe enough to use the hosted client
-your own. More info [here](https://www.etesync.com/faq/#web-client).
+in many cases, it's generally not preferable. It's recommended that you use signed
+releases which's signature you manually verify and are run locally!

+
+## Running your own
+
+You can either self-host your own client to be served from your own server, or
+better yet, just run an instance locally.
+
+First make sure you have `yarn` install.
+
+Then clone this repository `yarn`, run `yarn` and wait until all of the deps are installed.
+
+Then it's recommended you run `yarn build` to build a production ready client you should serve
+(even if run locally!) and then just serve the `build` directory from a web server.
+You could for exapmle use the python built-in web server by runnig `python3 -m http.server` from
+the build directory.
+
+Alternatively, you can run the debug server just to verify everything works. To do that,
+run `yarn start`.
