+```
+
+If you already have `Qt 6` from the Qt installer and do not want vcpkg Qt, you can point CMake at that Qt install with `-DCMAKE_PREFIX_PATH=...`, but you still need compatible `OpenSSL` and `zlib` development libraries for the embedded FreeRDP build.
+
 ## Notes
 
-- OrbitHub currently requires Qt6 Widgets and CMake 3.21+.
+- OrbitHub builds vendored `KodoTerm`, `libvterm`, and `FreeRDP` from `third_party/`.
-- Milestone 3 SSH sessions require an `ssh` client available on `PATH`.
 - If Qt is installed in a custom location, pass `-DCMAKE_PREFIX_PATH=/path/to/Qt/6.x.x/<toolchain>` to CMake.
+- Build output executable:
+  - Linux/macOS: `build/orbithub`
+  - Windows: `build\\orbithub.exe`
+
+## Linux Packaging
+
+Build a Debian package (`.deb`) from the current Linux build:
+
+```bash
+./packaging/linux/build-deb.sh
+```
+
+Output path:
+- `dist/orbithub_<version>_<arch>.deb`
