+**Cater to callback and promise crowds.**  
+Simple utility to allow your module to be consumed with a callback or promise. For Node.js and browsers.
+
+[![npm status](https://img.shields.io/npm/v/catering.svg)](https://www.npmjs.com/package/catering)
+[![Node version](https://img.shields.io/node/v/catering.svg)](https://www.npmjs.com/package/catering)
+[![Test](https://img.shields.io/github/workflow/status/vweevers/catering/Test?label=test)](https://github.com/vweevers/catering/actions/workflows/test.yml)

+
+## Menu
+
+If your module internally uses callbacks:
+
+```js
+const { fromCallback } = require('catering')
+const kPromise = Symbol('promise')
+
+module.exports = function (callback) {
+  callback = fromCallback(callback, kPromise)
+  queueMicrotask(() => callback(null, 'example'))
+  return callback[kPromise]
+}
+```
+
+If your module internally uses promises:
+
+```js
+const { fromPromise } = require('catering')
+
+module.exports = function (callback) {
+  return fromPromise(Promise.resolve('example'), callback)
+}
+```
+
+Either way your module can now be consumed in two ways:
+
+```js
+example((err, result) => {})
+const result = await example()
+```
+
+When converting from a promise to a callback, `fromPromise` calls the callback in a next tick to escape the promise chain and not let it steal your beautiful errors.
