+There is a checkout of a similar project under ./odbc-scanner which is the ODBC scanner for DuckDB extension. This adbc extension is modeled after that extension but uses the ADBC interface instead.
 
-There is also a checkout of the Airport DuckDB extension under ./airport.  The Airport extension integrates DuckDB with Apache Arrow Flight, but it demonstrates C++ code that can read Arrow record batches and return them to DuckDB. The docs for the extension are under ./airports/docs/README.md, but you're mostly going to be interested in airport_take_flight.cpp.

+## Extension Functions
+
+The extension provides the following functions:
+
+### Connection Management
+- `adbc_connect(options)` - Connect to an ADBC data source. Returns a connection handle (BIGINT). Options can be passed as a STRUCT (preferred) or MAP. The `driver` option is required.
+- `adbc_disconnect(handle)` - Disconnect from an ADBC data source. Returns true on success.
+
+### Query Execution
+- `adbc_scan(handle, query, [params := row(...)])` - Execute a SELECT query and return results as a table. Supports parameterized queries via the optional `params` named parameter.
+- `adbc_execute(handle, query)` - Execute DDL/DML statements (CREATE, INSERT, UPDATE, DELETE). Returns affected row count.
+
+### Catalog Functions
+- `adbc_info(handle)` - Returns driver/database information (vendor name, version, etc.).
+- `adbc_tables(handle)` - Returns list of tables in the database.
+
+### Example Usage
+
+```sql
+-- Connect to SQLite (driver path varies by installation)
+SET VARIABLE conn = (SELECT adbc_connect({'driver': '/path/to/libadbc_driver_sqlite.dylib', 'uri': ':memory:'}));
+
+-- Query data
+SELECT * FROM adbc_scan(getvariable('conn')::BIGINT, 'SELECT 1 AS a, 2 AS b');
+
+-- Parameterized query
+SELECT * FROM adbc_scan(getvariable('conn')::BIGINT, 'SELECT ? AS value', params := row(42));
+
+-- Execute DDL/DML
+SELECT adbc_execute(getvariable('conn')::BIGINT, 'CREATE TABLE test (id INTEGER, name TEXT)');
+SELECT adbc_execute(getvariable('conn')::BIGINT, 'INSERT INTO test VALUES (1, ''hello'')');
+
+-- Catalog functions
+SELECT * FROM adbc_info(getvariable('conn')::BIGINT);
+SELECT * FROM adbc_tables(getvariable('conn')::BIGINT);
+
+-- Disconnect
+SELECT adbc_disconnect(getvariable('conn')::BIGINT);
+```

 ## Architecture
 
-- **Extension entry point**: `src/adbc_extension.cpp` - Registers functions with DuckDB via `LoadInternal()`
+- **Extension entry point**: `src/adbc_extension.cpp` - Registers all functions with DuckDB via `LoadInternal()`
+- **ADBC functions**: `src/adbc_functions.cpp` - Implements connection management, scanning, catalog, and execute functions
 - **Extension class**: `src/include/adbc_extension.hpp` - Defines `AdbcExtension` class inheriting from `duckdb::Extension`
 - **Configuration**: `extension_config.cmake` - Tells DuckDB build system to load this extension
 - **Dependencies**: `vcpkg.json` - Depends on `arrow-adbc` via vcpkg with custom overlay ports in `vcpkg-overlay/`
 
-The extension currently registers a scalar function `adbc(varchar) -> varchar`. The ADBC driver manager is linked statically via `AdbcDriverManager::adbc_driver_manager_static`.
