        ## Installation
        ```
        pip install sqllex
        ```
        
        
        ## About
        Use databases without thinking about SQL. Let me show you how sqllex makes
        your life easier. Imagine you need create some database, save some data
        into it and take it back. That's how your code will look like.
        
        ### If you never used SQLite before read [this awesome example](https://github.com/v1a0/sqllex/wiki/SQLite3x-%7C-SIMPLEST-EXAMPLE#simplest-sqlite3x-example)  
        
        ```python
        from sqllex import *
        
        db = SQLite3x(                              
            path='my_data.db',                      
            template={                              
                "users": {                          
                    "username": [TEXT, NOT_NULL],   
                    "age": INTEGER,                 
                }                                   
            }                                       
        )
        
        users = db["users"]
        
        users.insert('Sqllex', 33)
        
        user = users.select('username', WHERE={'age': 33})
        
        print(users)  # ['Sqllex']
        ```

        <summary id="what1"><big>WHAT IS GOING ON THERE?!</big></summary>
        
        ```python
        from sqllex import *
        
        # Create some database, with simple structure
        db = SQLite3x(                              # create database
            path='my_data.db',                      # path to your database, or where you would like it locate
            template={                              # schema for tables inside your database
                "users": {                          # name for the 1'st table
                    "username": [TEXT, NOT_NULL],   # 1'st column of table, named "username", contains text-data, can't be NULL
                    "age": INTEGER,                 # 2'nd column of table, named "age", contains integer value
                }                                   # end of table
            }                                       # end of schema (template)
        )
        
        # Ok, now you have database with table inside it.
        # Let's add record of  33 years old user named 'Sqllex'
        # Dear db, please insert into 'users' table values ['Sqllex', 33]
        db.insert('users', ['Sqllex', 33])
        
        # Dear db, please select from table 'users' username(s) where column 'age' == 33
        users = db.select('users', 'username', WHERE={'age': 33})
        
        # Print it
        print(users)  # ['Sqllex']
        ```
        
        </details>
        
        Ok, what if you need more complex structure with FOREIGN KEYs? Not a big deal.
        
        ```python

            For the first, you need to import * (all) from Sqllex lib and init your database
