+# Datalite
+
+Datalite is a simple Python
+package that binds your dataclasses to a table in a sqlite3 database,
+using it is extremely simple, say that you have a dataclass definition,
+just add the decorator `@sqlify(db_name="db.db")` to the top of the
+definition, and the dataclass will now be bound to the file `db.db`
+
+For example:
+
+```python
+from dataclasses import dataclass
+from datalite import sqlify
+
+
+@sqlify(db_path="db.db")
+@dataclass
+class Student:
+    student_id: int
+    student_name: str = "John Smith"
+```
+
+This snippet will generate a table in the sqlite3 database file `db.db` with
+table name `student` and rows `student_id`, `student_name` with datatypes
+integer and text, respectively. The default value for `student_name` is
+`John Smith`.
+
+## Creating a new object instance
+
+If you create a new object with default Python methods, the object will not 
+be inserted into the table by default. However, the classes that are created
+with `datalite` has a argument in their init method. So, if you write
+`Student(1, create_entry=True)` rather than just saying `Student(1)`, the
+entry equivalent of the newly created student will be inserted into
+the table without any problems.
+
+## Deleting an object instance
+
+Another method that is added to any dataclass created with `datalite` is the
+`.remove()` method. By deleting a class with the `.remove()` you will also
+delete its equivalent entry from the database.
