+
+Let your JS API users either give you a callback or receive a promise.
+
+## Usage
+
+```javascript
+var maybe = require("call-me-maybe")
+
+module.exports = function asyncFunc (cb) {
+  return maybe(cb, new Promise(function(resolve, reject) {
+    // ...
+  }))
+}
+```
+
+## API
+
+### maybe(cb, promise)
+
+If the callback `cb` is truthy, returns `undefined` and will call `cb` when `promise` is settled. The parameters passed to `cb` are standard error-first:
+
+  - If `promise` is fulfilled, then it is called with the result of the promise: `cb(null, result)`
+  - If `promise` is rejected, then it is called with the rejection error: `cb(err)`
+
+If `cb` is falsey, then `promise` is returned.
