 ## Package Status
 
 This package is a fork of [IDE-TypeScript](https://github.com/atom/ide-typescript) which has been modified to use a different Language Server. Since Microsoft's [LSP](https://github.com/Microsoft/language-server-protocol) allows for essentially drop in replacements of servers I created this to resolve some of the [major issues](https://github.com/atom/ide-typescript/issues/113) [SourceGraph's LSP](https://github.com/sourcegraph/javascript-typescript-langserver) has (and their lack of willingness to fix said issues).
