+# Scheme
+
+[Scheme](https://www.scheme.org/) is a classic programming language in the Lisp family. It emphasizes functional programming and domain-specific languages but adapts to other styles.
+
+In LiveCodes, Scheme code runs in the browser using [BiwaScheme](https://www.biwascheme.org/), a Scheme interpreter written in JavaScript.
+
+:::info Note
+
+Lisp language family supported in LiveCodes includes [Common Lisp](./commonlisp.html.md), [Scheme](./scheme.html.md), [ClojureScript](./clojurescript.html.md) and [Fennel](./fennel.html.md).
+
+:::
+
+## Usage
+
+LiveCodes runs Scheme code in the browser. BiwaScheme [implements](https://www.biwascheme.org/doc/features.html) most of the features of [R7RS small](https://small.r7rs.org/), including first-class continuation and tail call optimization.
+
+**Example:**
+
+import LiveCodes from '../../src/components/LiveCodes.tsx';
+
+export const basicSchemeDemo = {
+  activeEditor: 'script',
+  markup: {
+    language: 'html',
+    content: `<div class="container">
+  <h1>Hello, <span id="title">World</span>!</h1>
+  <img class="logo" alt="logo" src="https://livecodes.io/livecodes/assets/templates/scheme.svg" />
+  <p>You clicked <span id="counter">0</span> times.</p>
+  <button id="counter-button">Click me</button>
+</div>
+`,
+  },
+  style: {
+    language: 'css',
+    content: `.container,
+.container button {
+  text-align: center;
+  font: 1em sans-serif;
+}
+.logo {
+  width: 150px;
+}
+`,
+  },
+  script: {
+    language: 'scheme',
+    content: `(let ((title "Scheme"))
+  (set-content! "#title" title))
+
+(let ((counter 0))
+(add-handler! "#counter-button" "click"
+(lambda (ev)
+(set! counter (+ counter 1))
+(set-content! "#counter" (number->string counter)))))
+
+; check console
+(let ((time-now (date-hour (current-date))))
+(console-log
+(cond ((< time-now 12) "Good morning")
+((< time-now 18) "Good afternoon")
+(else "Good evening"))))
+`
+}
+}
