+# Db Builder
+
+This package enables you to create your SQLite database from a json file
+that represent your tables.
+
+## Warnings
+
+DO NOT USE IN PRODUCTION ENVIRONNEMENT, this lib is quickly developed for my personal use !
+
+## Usage
+
+To use this lib, you need to call the facade struct `DbBuilderFacade` and give it
+the database path (the db file is created if needed) and the path to the json file that represent your db.
+
+Exemple:
+```rust
+fn main() {
+    let facade = DbBuilderFacade{};
+    
+    match facade.build("schema.json".to_string(), "exemple.db".to_string()) {
+        Ok(_) => println!("DB created"),
+        Err(message) => eprintln!("Error creating the db: {}", message)
+    }
+}
+```
