 # Skooma
-
-```js
-import {html} from "skooma/render.js"
-
-document.body.append(
-	html.p(
-		"This is a paragraph with some text ",
-		html.b("and some bold text "),
-		html.img({
-			alt: "And an image",
-			href: "http://picsum.photos/200/200"
-		})
-	)
-)
-```
-
-## Goals
-
-1. `skooma/render` should stay small enough to use it as just a helper library
-   to generate some dom nodes in any sort of web environment.
-1. `skooma/observable` should likewise function as a standalone reactive state
-   management library to be used with or without a framework
-1. A developer who doesn't use skooma should be able to read any code using it
-   and piece together what it does based on structure and function names
-1. Skooma should be easy to gradually introduce into an application that uses
-   a different framework or no framework at all
-1. Skooma should make it easy to gradually replace it with a different solution
-   should it prove unfit for a project it is being used in
-1. The library should be hackable so that developers can tweak it for different
-   environments like SSR or frameworks
-
-## Warning
-
-**This branch is in the process of being aggressively refactored and improved.
-This readme file may not reflect the latest state of the interface.**
-
-## Overview
-
-```js
-const text = new State({value: "Skooma is cool"})
-setTimeout(() => {text.value = "Skooma is awesome!"}, 1e5)
-
-document.body.append(html.div(
-    html.h1("Hello, World!"),
-    html.p(text, {class: "amazing"}),
-    html.button("Show Proof", {click: event => { alert("It's true!") }})
-))
-```
-
-## Interface / Examples
-
-### Basic DOM generatio
-
-Accessing the `html` proxy with any string key returns a new node generator
-function:
-
-```js
-html.div("Hello, World!")
-```
-
-Attributes can be set by passing objects to the generator:
-
-```js
-html.div("Big Text", {style: "font-size: 1.4em"})
-```
-
-Complex structures can easily achieved by nesting generator functions:
-
-```js
-html.div(
-    html.p(
-        html.b("Bold Text")
-    )
-)
-```
-
-For convenience, arrays assigned as attributes will be joined with spaces:
-
-```js
-html.a({class: ["button", "important"]})
-```
-
-Assigning a function as an attribute will instead attach it as an event
-listener:
-
-```js
-html.button("Click me!", {click: event => {
-    alert("You clicked the button.")
-}})
-```
-
-<!-- TODO: Document special keys -->
-
-Generators can be called with many arguments. Arrays get iterated recursively as
-if they were part of a flat argument list.
-
-### Generating Text Nodes
-
-```js
-text("Hello, World")
-// Wraps document.createTextNode
-text()
-// Defaults to empty string instead of erroring
-text(null)
-// Non-string arguments still error
-
-text`Hello, World!`
-// returns a new document fragment containing the text node "Hello, World!"
-text`Hello, ${user}!`
-// returns a document fragment containing 3 nodes:
-// "Hello, ", the interpolated value of `user` and "!"
-text`Hello, ${html.b(user)}!`
-// Text node for Hello, the <b> tag with the user's name, and a text node for !
-```
-
-## handle
-
-```js
-import {handle} from 'skooma/state.js'
-```
-
-Since it is common for event handlers to call `preventDefault()`, skooma
-provides a helper function called `handle` with the following definition:
-
-```js
-fn => event => { event.preventDefault(); return fn(event) }
-```
-
-## A few more examples:
-
-Create a Button that deletes itself:
-
-```js
-document.body.append(
-	html.button("Delete Me", {click: event => event.target.remove()})
-)
-```
-
-Turn a two-dimensional array into an HTML table:
-```js
-const table = rows =>
-	html.table(html.tbody(rows.map(
-		row => html.tr(row.map(
-			cell => html.rd(cell, {dataset: {
-				content: cell.toLowerCase(),
-			}})
-		))
-	)))
-```
-
-A list that you can add items to
-```js
-let list, input = ""
-document.body.append(html.div([
-	list=html.ul(),
-	html.input({type: 'text', input: e => input = e.target.value}),
-	html.button({click: event => list.append(html.li(input))}, "Add"),
-]))
-```
-
-A list that you can also delete items from
-```js
-const listItem = content => html.li(
-	html.span(content), " ", html.a("[remove]", {
-		click: event => event.target.closest("li").remove(),
-		style: { cursor: 'pointer', color: 'red' },
-	})
-)
-let list, input = ""
-document.body.append(html.div([
-	list=html.ul(),
-	html.input({type: 'text', input: e => input = e.target.value}),
-	html.button({click: event => list.append(listItem(input))}, "Add"),
-]))
-```
