   - To generate the .dmg for distribution, you will need Node.js and create-dmg installed. If you do not have create-dmg installed, get it with ```npm install --global create-dmg```.

+1. **Generate the deployment .exe**: Qt has a handy-dandy application called windeployqt that packages all the .dlls, resources and other dependencies into the same folder as the .exe.
+  - Run it with `windeployqt ./jyut-dict.exe` in the directory where the program was built. (Here, use the release folder.)
+  - Note: you may need the full path of windeployqt, and set the appropriate environment variables. Find the appropriate version by looking in the folder where you installed Qt, which on Windows may be located in the `msvc_<year>` folder if using Microsoft Visual C++, or `mingw<version>_64` if using MinGW/GCC for Windows.
+
+2. **Create a .msi file**: Windows users expect an installer that automatically places frameworks and executables in the right places, as well as setting registry keys as necessary.
+  - To generate the .msi for distribution, you will need Advanced Installer.
+  - Add the .dlls, folders, database files, and executable generated by Qt Creator and windeployqt to the list of files and folders in Advanced Installer, then click 'Build' to generate a .msi file.
