+This repo provides the [Harlequin](https://harlequin.sh) adapter for [ADBC](https://arrow.apache.org/adbc) (Arrow Database Connectivity).
 
 ## Warning
+
 ADBC is a very new database connectivity method compared to ODBC, JDBC that aims at providing a more efficient way to transfer columnar data over the wire.
 
 Due to the recency of its development, there is various level of functionality across drivers which may cause issues.

 ## Usage and Configuration
+
 You can open Harlequin with the ADBC adapter by selecting it with the `-a` option and passing in a connection string. The format of the connection string will depend on the driver you are using. You will also need to provide either the `--driver-type` or the `--driver-path`.
 
 ### Driver Type (preferred)
-When you use the --driver-type option it will try to dynamically use the driver package of the type selected `adbc-driver-{driver type}`. That is why it's crucial to also have that package also install in the virtual environment where Harlequin is installed.

 - `--driver-type` with one of the following options
   - flightsql, postgresql, snowflake, sqlite, duckdb
 
 ### Driver Path
+
 The other option is to pass the file path location of the adbc driver that you are using. Note this method is not well tested.
+
 - `--driver-path`
 
 ### DB Kwargs String (Optional)
+
 Since the drivers implement so many different options to pass through when you connect to the database this is a way to pass through these options. The format of the string is key=value separated by ;

 - `--db-kwargs-str`

 This will parse the string and pass through these values into the `db_kwargs` value in the `dbapi.connect()` method. Note the parser relies on the ; and = so if any of of the parameters in the string contain either of these characters it's not going to work. This is a known limitation and something being worked on.
 
 ### Snowflake Driver
+
 The Snowflake URI should be of one of the following formats:
 
 - `user[:password]@account/database/schema[?param1=value1&paramN=valueN]`
 - `user[:password]@account/database[?param1=value1&paramN=valueN]`
 - `user[:password]@host:port/database/schema?account=user_account[&param1=value1&paramN=valueN]`
 - `host:port/database/schema?account=user_account[&param1=value1&paramN=valueN]`

 ### Postgres Driver
+
 The Postgres URI should be in the format of a [Postgres DSN](https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNSTRING):
 
-`harlequin -a postgres "postgres://my-user:my-pass@localhost:5432/my-database"`
+`harlequin -a adbc "postgres://my-user:my-pass@localhost:5432/my-database" --driver-type postgresql`
 
 ### DuckDB and SQLite
+
 While DuckDB and SQLite both have ADBC drivers it's not recommend to use them. Harlequin natively supports both of the databases without having to install any other dependencies.
 
 ## Know Issues
+
 - Snowflake adbc driver seems to be the only driver that returns the `xdbc_data_type` from `adbc_get_objects()`
 - Snowflake adbc driver has a bug with `adbc_get_table_schema()` that returns `adbc_driver_manager.OperationalError: IO: sql: expected 12 destination arguments in Scan, not 11`
 - The PostgreSQL adbc driver is overall buggy and when executing queries you might get the error `IO: [libpq] Fetch header failed: no COPY in progress`
