-## Pre-conversion of Modules
-
-noVNC is written using ECMAScript 6 modules. Many of the major browsers support
-these modules natively, but not all. By default the noVNC application includes
-a script that can convert these modules to an older format as they are being
-loaded. However this process can be slow and severely increases the load time
-for the application.
-
-It is possible to perform this conversion ahead of time, avoiding the extra
-load times. To do this please follow these steps:
-
- 1. Install Node.js
- 2. Run `npm install` in the noVNC directory
- 3. Run `./utils/use_require.js --with-app --as commonjs`
-
-This will produce a `build/` directory that includes everything needed to run
-the noVNC application.
