-## Steps to Register the 64-bit Apache Arrow ODBC driver on Windows
+## Steps to Register the Apache Arrow Flight SQL ODBC driver
 
-After the build succeeds, the ODBC DLL will be located in 
-`build\debug\Debug` for a debug build and `build\release\Release` for a release build.
+After building the repository you will find the built ODBC binaries in the build artifacts.
 
-1. Open Windows Power Shell as administrator.
+On Windows, the driver binary will be located at `C:\path\to\arrow\cpp\build\debug\Debug\arrow_flight_sql_odbc.dll` for a debug build and `C:\path\to\arrow\cpp\build\release\Release\arrow_flight_sql_odbc.dll` for a release build.
 
-2. Register your ODBC DLL:
+On macOS, the driver binary will be located at `/path/to/arrow/cpp/build/debug/libarrow_flight_sql_odbc.dylib` for a debug build and `/path/to/arrow/cpp/build/release/libarrow_flight_sql_odbc.dylib` for a release build.
 
-   Need to replace `<path\to\repo>` with actual path to repository in the commands.
+On Linux, the driver binary will be located at `/path/to/arrow/cpp/build/debug/libarrow_flight_sql_odbc.so` for a debug build and `/path/to/arrow/cpp/build/release/libarrow_flight_sql_odbc.so` for a release build.
 
-   1. `cd <path\to\repo>`
-   2. Run script to register your ODBC DLL as Apache Arrow Flight SQL ODBC Driver
+1. Open your system terminal. On Windows this should be PowerShell in administrator mode.

+2. Register your ODBC binary:
+
+   1. Navigate to the root of the Arrow repo.
+   2. Run script to register your ODBC driver binary as Apache Arrow Flight SQL ODBC Driver.<br>

+# Connection Properties on Apache Arrow Flight SQL ODBC Driver
+
+## Setting ODBC Connection Properties
+
+ODBC connection parameters can be set in a connection string or defined in a DSN. On macOS and Linux, DSNs are typically defined in your system's `odbc.ini`. On Windows they are typically configured with the ODBC Data Source Administrator.
+
+The following sample connection string and sample DSN are two equivalent ways to connect to Arrow.
+
+### Sample Connection String
+```
+driver={Apache Arrow Flight SQL ODBC Driver};host=127.0.0.1;port=12345;uid=sample_user;pwd=sample_password;useEncryption=false;useWideChar=true;
+```
+
+### Sample DSN
+```
+[Apache Arrow Flight SQL]
+driver        = Apache Arrow Flight SQL ODBC Driver
+host          = 127.0.0.1
+port          = 12345
+uid           = sample_user
+pwd           = sample_password
+useEncryption = false
+useWideChar   = true
+```
+
+### Driver Connection Options
+| Option | Description | Default |
+|--------|-------------|---------------|
+| `driver` | Required: the driver for this ODBC driver. | `Apache Arrow Flight SQL ODBC Driver` |
+| `dsn` | Data Source Name used for configuring the connection. | `Apache Arrow Flight SQL` |
+| `host` | The IP address or hostname for the server. | `NONE` |
+| `port` | The TCP port number the server uses for ODBC connections. | `NONE` |
+| `user` | The username for authentication to the server. | `NONE` |
+| `user id` | The username for authentication to the server. | `NONE` |
+| `uid` | The username for authentication to the server. | `NONE` |
+| `password` | The password for authentication to the server. | `NONE` |
+| `pwd` | The password for authentication to the server. | `NONE` |
+| `token` | The personal access token for authentication to the server. | `NONE` |
+| `useEncryption` | Setting to determine if an SSL-encrypted connection should be used. | `true` |
+| `disableCertificateVerification` | Setting to determine if the driver should verify the host certificate against the trust store. | `false` |
+| `trustedCerts` | The full path of the .pem file containing certificates for the purpose of verifying the server. | `NONE` |
+| `useSystemTrustStore` | Setting to determine whether to use a CA certificate from the system's trust store or from a specified .pem file. | `true` on Windows, `false` on macOS & Linux |
+| `stringColumnLength` | Maximum length of a string column. Some apps may require a lower length. | `NONE` |
+| `useWideChar` | Setting to determine if wide characters should be used. Important for Unicode applications. | `true` on Windows, `false` on macOS & Linux |
+| `chunkBufferCapacity` | Capacity of a chunk buffer. Larger values will improve throughput at the cost of increased memory usage. | 5 |
