-### More Info
-
-The only available function in Scaffe is `generate` which takes arguments as
-following in order.
-
-- `templateDir`: It's the path to the template directory. <br>
-- `outDir`: The output directory <br>
-- `config`: An Object with two props `{boolean} overwrite (by default false)`, `{object} variables` <br>
-
 **Template directory can have two types of files** <br>
 - `starts with _`: this file will be evaluated as an ejs file <br>
 - `doesn't starts with _`: this type of files will be copied as it is to the output directory.
