 ## Usage
 
-```bash
+```javascript
 import { createModel } from 'mobx-form';
 
-createModel({
-  email: '',
+const model = createModel({
+  // the fields that will hold the initial data
+  fieldName: '',
 }, {
-  email: {
-    fn(field) {
+  // the validators by fieldName.
+  // when calling model.validate(); all the validators are executed sequentially
+  fieldName: {
+    // whether validation will happen after first update. Default true.
+    // sometimes is annoying
+    interactive: true,
+    // whether validation should wait until the field is blurred at least once
+    // (meaning the blur event happened at least once in that field). The main
+    // limitation here is that `onBlur` of the field is required to call the method
+    // `markBlurredAndValidate();`
+    waitForBlur: false,
+    // if this prop has no value validation will fail with an error message
+    // equal to the prop's value
+    // if `required` is set. `fn` is optional.
+    required: 'This field is required',
+    // optional, default error message is the function return just true/false
+    errorMessage:
+    // optional, if `required` is defined. Required if not
+    // the validation function it receive the current field and allFields for
+    // validations that need to take in consideration more than one in conjuction
+    //
+    // - if validation passes function must return true.
+    // - if validation does not pass the function should:
+    //   - return false (default errorMessage specified in the validator will be used)
+    //   - throw an error (error.message is going to be used as the errorMessage)
+    //   - reject or return an object with an error field. like:
+    //     ```
+    //     return { error: 'some error' };
+    //     return Promise.reject({ error: 'some error' }); // although this should be considered deprecated

+      // do validation
       // return true/false

+      // return Promise.reject({ error: 'some error '}).

+  const obj = model.serializedData;
+};
+
+// To reset the initial values
+model.restoreInitialValues();
+
+// To reset the validation
+model.clearValidations();
+
+// To get the summary of all the errors
+model.summary // Array or error messages
+
+// To know if the model was interacted
+model.interacted // true if at least one field has a value set
+
+// To know if all required fields have values
+model.requiredAreFilled // true if all fields marked as required are filled
+
+// To know if the data is ready to serialize
+model.dataIsReady // true if interacted, requiredAreFilled and valid are true.
+
+// to know which fields are required
+model.requiredFields // an array with the required fieldNames
+
+// to update values in the form
+// by default setting values using this method will reset the interacted flag on the Field and reset the validation error
