 ```

 The built artifacts will end up in `build_dir/goldendict`
 
-To run the built `goldendict.exe` directly, you have to add `F:\Qt\6.5.2\msvc2019_64\bin` to your PATH environment variable
+#### Using pre-built winlibs
 
-To have a redistributable goldendict (runable on someone else's computer by just copying the folder), you can build the deployment target which will copy necessary files to the folder
+Use `windeploy` target to copy necessary runtime files.
 
 ```
 cmake --build . --target windeploy
 ```
 
-The `build_dir/goldendict` will be ready to share with others.
+Or you can also manually run `windeployqt.exe {your_build_dir}/goldendict.exe` which will copy the qt related things to `build_dir`.
 
-Use`windeployqt.exe {your_build_dir}/goldendict.exe` which will copy the qt related `.dll` and other necessary files automatically.
+#### Using Vcpkg
 
+The dependencies can be built via Vcpkg instead of using the pre-built ones.
+
+Vcpkg CMake build utilize the "manifest mode", all you need to do is basically 
+set `CMAKE_TOOLCHAIN_FILE` as described [here](https://learn.microsoft.com/en-us/vcpkg/consume/manifest-mode?tabs=cmake%2Cbuild-MSBuild#2---integrate-vcpkg-with-your-build-system).
+
+Add this to cmake command:
+```sh
+-DUSE_VCPKG=ON
+```
+
+Most `.dll` built by vcpkg will be automatically copied, but the Qt ones won't.
+
+You can
+* run `cmake --install .` (recommended)
+* manually run windeployqt
+* add `${Qt's install path}\Qt\6.5.2\msvc2019_64\bin` to your PATH environment variable
