 Let's you to use both SqlAlchemyst and MongoAlchemyst libraries
-Les's to use a unique ORM to manage the persistence in one project. 
+Les's to use a unique ORM to manage the persistence in one project. 
+
+## How to Use?
+You need to configurate a dictionary with the next parameters:
+db_config = {
+    "type":"mongo",
+    "host": "localhost",
+    "port":27017,
+    "user":"",
+    "database":"google",
+    "password":"",
+    "SQLALCHEMY_TRACK_MODIFICATIONS":True
+}
+
+- *** type: ***  mongo | mysql
+- *** host: ***  Host where the database is
+- *** port: ***  Port of engine runs
+- *** user: ***  User
+- *** databse: ***  Name of database
+- *** password: ***  Password
+
+How you see, you can to specify other attributes of the ORM, like "SQLALCHEMY_TRACK_MODIFICATIONS".
+
+After to set the configuration that you want to use, you have to create a FullAlchemyst instance:
+
+```
+app = Flask(__name__)
+fullAlchemyst= FullAlchemyst(app,db_config)
+```
+
+Obviusly, What is a ORM without models? Create one:
+
+```
+class task(fullAlchemyst.Entity):
+    id = define(fullAlchemyst.db, {"name":"id","type":"int","primary_key":True})
+    nombre = define(fullAlchemyst.db, {"name":"nombre","type":"str"})
+```
+
+### Steps:
+1. First, you need to extend you model of fullAlchemyst.Entity
+2. Define your attributes. In this step, remember to use the "define" function. We see this later
+
+### "define" function
+This function is used to configurate you model depending what type of database you use.
+
+This function, receives a dict, and its structure is the next:
+- type : int | str o another inside de buildins of python.
+- primary_key : If you attribute is a primary key.
