+
+### Promisify an entire object or class instance
+
+This module leverages es6 Proxy and Reflect to promisify every function in an
+object or class instance.
+
+It assumes the callback that the function is expecting is the last
+parameter, and that it is an error-first callback with only one value,
+i.e. `(err, value) => ...`. This mirrors node's `util.promisify` method.
+
+In order that you can use it as a one-stop-shop for all your promisify
+needs, you can also pass it a function.  That function will be
+promisified as normal using node's built-in `util.promisify` method.
+
+[node's custom promisified
+functions](https://nodejs.org/api/util.html#util_custom_promisified_functions)
+will also be mirrored, further allowing this to be a drop-in replacement
+for the built-in `util.promisify`.
+
+### Examples
+
+Promisify an entire object
+
+```javascript
+
+const promisify = require('@gar/promisify')
+
+class Foo {
+  constructor (attr) {
+    this.attr = attr
+  }
+
+  double (input, cb) {
+    cb(null, input * 2)
+  }
+
+const foo = new Foo('baz')
+const promisified = promisify(foo)
+
+console.log(promisified.attr)
+console.log(await promisified.double(1024))
+```
+
+Promisify a function
+
+```javascript
+
+const promisify = require('@gar/promisify')
+
+function foo (a, cb) {
+  if (a !== 'bad') {
+    return cb(null, 'ok')
+  }
+  return cb('not ok')
+}
+
+const promisified = promisify(foo)
+
+// This will resolve to 'ok'
+promisified('good')
+
+// this will reject
+promisified('bad')
+```
