 ## [Unreleased]
 
+### Added (documentation)
+- Microsoft Foundry Local BYOK provider guide in `doc/auth/byok.md`: quick start example, installation instructions, and connection troubleshooting (upstream PR #461).
+
 ### Added (upstream PR #329 sync)
 - Windows console window hiding: CLI process is spawned with explicit PIPE redirects ensuring the JVM sets `CREATE_NO_WINDOW` on Windows — no console window appears in GUI applications. Equivalent to upstream `windowsHide: true` (upstream PR #329).

+## Quick Start: Microsoft Foundry Local
+
+[Microsoft Foundry Local](https://foundrylocal.ai) lets you run AI models locally on your own device with an OpenAI-compatible API. No API key is needed.
+
+> **Note:** Foundry Local starts on a **dynamic port** — the port is not fixed. Use `foundry service status` to confirm the port the service is currently listening on, then use that port in your `:base-url`.

+# macOS / Linux: see https://foundrylocal.ai for installation instructions

+Foundry Local uses a dynamic port that may change between restarts. Confirm the active port:
