## Explanation
The **Frames Protocol**, also known **Farcaster Frames**, is a simple web-based technology used for making applications.
It uses HTML without really using HTML, so that **Frames Protocol** applications work with clients that don't support the **Frames Protocol**.
The fall-back being OpenGraph.
Really, a **Frames Protocol** application is mostly made up of **images** and **buttons** on the client-side (that are specified using HTML `` element) with a back-end that gets HTTP `POST`ed to, which can return a new "page" with an **image** and **buttons**, and so on and so on.
This choice of just being mostly **images** and **buttons** actually makes the **Frames Protocol** simpler to create a viewer from scatch.
No need to implement all Web technologies.
No need to worry about security and privacy holes that Web technologies introduce.
Although the **Frames Protocol** _could_ be used outside of **Farcaster**, at the time of writing, **Farcaster** clients (such as **Warpcast**) are the only major (client-side) platform to support it.
(The server-side of the Frames Protocol, which is called a Frame Server, is an just HTTP resource — which some might loosely call an HTTP (or HTTPS) URL.)
Enough talking — let's look at some code.
Here is the client-side of a **Frames Protocol** application:
```html
```
It is just HTML.
Although this would need to be embedded into an HTML document, so really it would be something more like this:
```html
```
This package provides you tools for creating this.
For example:
```golang
func ServeHTTP(responseWriter http.ResponseWriter, request *http.Request) {
// ...
frameproto.WriteFrame(responseWriter, frameproto.VersionVNext)
frameproto.WriteFrameImage(responseWriter, frameImageURL)
// ...
}
```
