 ### Step 5. (Optional) Install Qt
 
 If you would like to compile Qt instead of using the precompiled package provided during CMake, you can do so now. Install version 5.12.3 of [Qt](<https://www.qt.io/download-open-source>), as well as the following packages:
-* Qt 5.12.3

 ### Step 6. Create VCPKG environment variable
 In the next step, you will use CMake to build Vircadia. By default, the CMake process builds dependency files in Windows' `%TEMP%` directory, which is periodically cleared by the operating system. To prevent you from having to re-build the dependencies in the event that Windows clears that directory, we recommend that you create a `HIFI_VCPKG_BASE` environment variable linked to a directory somewhere on your machine. That directory will contain all dependency files until you manually remove them.
