Wtf does this do

This repository contains the source code for Visual Studio Code, the popular free code editor from Microsoft. The repo, called "Code - OSS," is where Microsoft and the open-source community work together to build the product. It gives developers a streamlined tool for the core "edit-build-debug" cycle, writing code, turning it into runnable programs, and fixing problems, all in one application. At its core, the project is a text editor designed specifically for programmers. It goes beyond simple text editing by offering code navigation, syntax highlighting for many languages, and lightweight debugging tools. The repo also includes a set of built-in extensions (small add-ons) that provide features like auto-complete and color coding for different programming languages. Notably, the version of the editor people download from the website is a distribution of this open-source code with additional Microsoft-specific customizations released under a separate product license. The project is built primarily in TypeScript and is openly developed on a monthly release cycle. Microsoft publishes its roadmap and iteration plans publicly, so you can see what features are coming next. The repo also includes a "development container" setup, which lets contributors spin up a pre-configured coding environment without having to manually install all the dependencies on their own machine. Anyone can participate in the project. You can submit bug reports, request features, review code changes, or fix issues directly. Microsoft provides a "How to Contribute" guide covering the workflow for submitting code, running tests, and following their coding guidelines. The source code is available to everyone under the MIT license, one of the most permissive open-source licenses.
