+# FlightSQL ODBC
+
+This repository contains Dremio's Flight SQL ODBC driver implementation, supporting libraries, and a small ODBC performance-testing tool.
+
+## Layout
+
+- `flight_sql/` - core Flight SQL ODBC driver sources, configuration handling, UI code, and unit tests.
+- `odbcabstraction/` - ODBC abstraction layer used by the driver.
+- `odbc_perf_testing/` - Python-based profiling and performance test helpers.
+- `build_win32.bat` - Windows x86 build entrypoint.
+- `build_win64.bat` - Windows x64 build entrypoint.
+- `vcpkg.json` - native dependency manifest.
+
+## Build
+
+The repository is built with CMake and uses `vcpkg` for native dependencies.
+
+Windows convenience scripts:
+
+```bat
+build_win64.bat
+build_win32.bat
+```
+
+The Windows scripts expect:
+
+- `VCPKG_ROOT` to point at a prepared `vcpkg` checkout
+- `ARROW_GIT_REPOSITORY` optionally set to an Apache Arrow repository or fork
+
+For non-Windows builds, use the top-level `CMakeLists.txt` directly and make sure Boost plus an ODBC implementation are available. On macOS, the project is set up for `libiodbc`.
+
+## Testing
+
+- `flight_sql/` includes GoogleTest-based unit tests that build with the CMake targets.
+- Performance/profiling helpers live under [odbc_perf_testing/README.md](odbc_perf_testing/README.md).
+
+## Notes
+
+- This repo is separate from the packaging-oriented `odbc/` repository.
+- The checked-in batch scripts are the clearest starting point for reproducing the intended Windows build flow.
