 #### How it works?
 
+Micro-form reads a json file to render an Html form. The json file is just an object with three properties: name, inputs, repeat.
+
+* _name_ is the name of the array of inputs.
+* _inputs_ is an array objects that represents the inputs.
+* _repeat_ is a boolean value to set the array of inputs repeatable.
+
+The json used to render the form has to validated against this [Json-schema](https://github.com/marcomilon/micro-form/blob/master/src/form/schemas/input.json).
