##What is this extension? Do I need it?

TL;DR: If you are running VS Code, Code OSS or derived product built from the VS Code repository, such as VSCodium, you do not need to install this extension since it's already present - "built-in".

Built-in extensions are built-along and included in VS Code and Code OSS. In consequence they may be expected to be present and used by other extensions. They are part of the vscode GitHub repository and generally contribute basic functionality such as textmate grammars, used for syntax-highlighting, for some of the most popular programming languages. In some cases, more substantial features are contributed through built-in extensions (e.g. Typescript, Markdown, git, ...). Please see the description above to learn what this specific extension does.
