-# 0http-bun
-Bun-based HTTP framework inspired by 0http
+# Introduction
+Experimental, bun-based HTTP framework inspired by 0http!
+
+## Usage
+```js
+const http = require('0http-bun')
+
+const { router } = http({})
+router.use((req, next) => {
+  req.ctx = {
+    engine: 'bun'
+  }
+
+  return next()
+})
+router.get('/:id', async (req) => {
+  return Response.json(req.params)
+})
+router.post('/', async (req) => {
+  return new Response('POST')
+})
+router.delete('/:id', async (req) => {
+  return Response.json(req.params, {
+    status: 200
+  })
+})
+
+module.exports = {
+  port: 3000,
+  fetch: (request) => router.lookup(request)
