+# signal-promise
+
+Simple wait/notify promise with optional max wait time
+
+```
+npm install signal-promise
+```
+
+## Usage
+
+``` js
+const Signal = require('signal-promise')
+
+const input = new Signal()
+
+while (await input.wait()) {
+  console.log('someone typed!')
+}
+
+process.stdin.on('stdin', function () {
+  input.notify()
+})
+```
+
+## API
+
+#### `s = new Signal()`
+
+Make a new signal
+
+#### `await s.wait([maxWaitTime])`
+
+Wait for someone to call notify. If you specify `maxWaitTime`
+the promise will resolve after `maxWaitTime` ms if no notify call has happened.
+
+As a convenience the promise resolves to `true` so it's easy to use it as a condition.
+
+#### `s.notify([error])`
+
+Notify everyone waiting. If you pass an error the wait promise
+will reject with that error.
