+# Connection String
+
+When creating a new SQLite database or connection to an existing one, with the file name additional options can be given.
+This is also known as a DSN string. (Data Source Name).
+
+Options are append after the filename of the SQLite database.
+The database filename and options are seperated by an `?` (Question Mark).
+
+This also applies when using an in-memory database instead of a file.
+
+Options can be given using the following format: `KEYWORD=VALUE` and multiple options can be combined with the `&` ampersand.
+
+This library supports dsn options of SQLite itself and provides additional options.
