 ## Type
 If the data has not the specifed type, validation will fail, and that field will not be added to final validated data.
 
+It uses typeof, so arrays will be considered valid objects. Also, there is a type "array", wich ensures data is an array.

+## Email
+Check if data is an email. Might be just a boolean, or an object to check domains:
+
+```javascript
+{
+	email: Boolean	// Check if data is an email
+}
+```
+
+Also, to check domains:
+```javascript
+{
+	email: {
+		domain: 'gmail.com'
+	}
+}

+
+Or, to enable more than one valid domains:
+```javascript
+{
+	email: {
+		domain: ['gmail.com', 'google.com']
+	}
+}
+```
+
+## Regex
+Test a regular expression over the data.
+```javascript
+{
+	regex: Regex	// Check if data is regex valid
+}
+```
+An example might be:
+```javascript
+{
+	regex: /[a]/
+}
+```
+This will validate `asd` but not `sdf`
