 In Simple Scaffold v1.0, the entire codebase was overhauled, yet usage remains mostly the same
 between versions. With these notable exceptions:
 
 - Some of the argument names have changed
 - Template syntax has been improved
+- The command to run Scaffold has been simplified from `new SimpleScaffold(opts).run()` to
+  `SimpleScaffold(opts)`, which now returns a promise that you can await to know when the process
+  has been completed.
 
 ## Argument changes
 
-- `locals` has been renamed to `data`. The appropriate command line args have been updated as
-  well to `--data` | `-d`.
+- `locals` has been renamed to `data`. The appropriate command line args have been updated as well

+ * Create a scaffold using given `options`.
+ *
+ * #### Create files
+ * To create a file structure to output, use any directory and file structure you would like.
+ * Inside folder names, file names or file contents, you may place `{{ var }}` where `var` is either
+ * `name` which is the scaffold name you provided or one of the keys you provided in the `data` option.
+ *
+ * The contents and names will be replaced with the transformed values so you can use your original structure as a
+ * boilerplate for other projects, components, modules, or even single files.
+ *
+ * The files will maintain their structure, starting from the directory containing the template (or the template itself
+ * if it is already a directory), and will output from that directory into the directory defined by `config.output`.
+ *
+ * #### Helpers
+ * Helpers are functions you can use to transform your `{{ var }}` contents into other values without having to
+ * pre-define the data and use a duplicated key.
+ *
+ * Any functions you provide in `helpers` option will also be available to you to make custom formatting as you see fit
+ * (for example, formatting a date)
+ *
+ * For available default values, see {@link DefaultHelpers}.
+ *
+ * @param {ScaffoldConfig} config The main configuration object

+ *   (
+ *     date: string,
+ *     format: string,
+ *     offsetAmount?: number,
+ *     offsetType?: "years" | "months" | "weeks" | "days" | "hours" | "minutes" | "seconds"
+ *   )
+ *   ```
+ *
+ * - **The now helper** (for current time) takes the same arguments, minus the first one (`date`) as it is implicitly
+ *   the current date.
