+	- Parameters (app: App, fileName: string)
+	- Return: Promise<CSVTable | null>
+	> Takes a filename and returns the corresponding CSVTable.
 
-- `saveCSV`
-	- Parameters: `(app: App, fileName: string, table: CSVTable)`
-	- Returns: `void`
-	> Saves the given `CSVTable` data to the specified `fileName`.

-## How It Works
+#### Header (type)
+
+#### CSVRow (type)
+
+#### CSVCellType (type)
+
+
+## How it Works
 When you create a CSV file using this plugin, two files are generated: `.csv` and `.csv.meta`.
+If you load an existing CSV file, a `.csv.meta` file is generated automatically.
 
-If you load an existing CSV file, a `.csv.meta` file will be generated automatically.
-
-The `.csv` file contains basic table data, while the `.meta` file stores metadata about the columns, such as their attributes. In the current version (`v0.1.0`), the `.meta` file only stores the type of each column, but future updates will include features like data/select values, validity constraints, and more.
