Make sure to add a reference to Ooui before you start running!

With just that code, the user will be presented with a silly counting button.
With just that code, a web server that serves the HTML and web socket logic necessary for an interactive button will start.
In fact, any number of users can hit that URL and start interacting with the same button. That's right, automatic collaboration!
If you want each user to get their own button, then you will instead `Publish` a **function** to create it:
```csharp
Button MakeButton()
{
var button = new Button("Click me!");
var count = 0;
button.Click += (s, e) => {
count++;
button.Text = $"Clicked {count} times";
};
return button;
}
## The Many Ways to Ooui
UI.Publish("/button", MakeButton);
```
Ooui has been broken up into several packages to increase the variety of ways that it can be used. Here are some combinations to help you decide which way is best for you.
Now every user (well, every load of the page) will get their own button.

## How it works
When the user requests a page, Ooui will connect to the client using a Web Socket. This socket is used to keep an in-memory model of the UI (the one you work with as a programmer) in sync with the actual UI shown to the user in their browser. This is done using a simple messaging protocol with JSON packets.

This is done using a simple messaging protocol with JSON packets.
When the user clicks or otherwise interacts with the UI, those events are sent back over the web socket so that your code can deal with them.

In the case of web assembly, this same dataflow takes place. However, sockets are not used as all communication is done locally in the browser process.

Ooui is open source and I love merging PRs. Please fork away, and please obey the .editorconfig file. :-) Try to file issues for things that you want to work on *before* you start the work so that there's no duplicated effort. If you just want to help out, check out the issues and dive in!
