+## Create Database
+
+*Syntax:* public function createDatabase($file)
+
+*Params:* `$file` filename
+
+Mainly use in the constructor
+
+*Example:*
+
+`$xmldb = new XMLDB('test.xml', 'id', true);`
+
+*Particular Behaviour:*
+
+Thanks to the constructor, you can manage your DB `__construct($file, $pk = "id", $createIfNotExist = false, $databaseName = "Database", $tableName = "table", $itemName = "item", $encoding = "utf-8")`
+We advise you to stay with default params anyway.
+
+## Drop Database
+
+*Syntax:* `public function dropDatabase($definitely = false)`
+
+*Params:* `$definitely` boolean do you wanna delete the file too ?
+
+*Example:* `$xmldbtest->dropDatabase();` will reset your DB, but your file'll still exist on your server.
+
+## Create Table
+
+*Syntax:* `public function createTable($name, $autoincrement = false, $aiDefaultValue = 0)`
+
+*Example:* `$xmldbtest->createTable('table1', true, 2)`
+
+The new table will append in your DB. Therefore, it'll be the last table in the file (if it might help).
+*New:* You can now configure each table with an autoincrement index. 
+
+h2. Drop Table
+
+*Syntax:* `public function dropTable($table)`
+
+*Example:* `$xmldbtest->dropTable('table1')`
+
+This will delete the table with the given name.
