-For Eclipse, Rascal uses the services of the IDE Meta-tooling Platform, or [IMP](http://www.eclipse.org/imp/) for short, a collection of API and tools to support constructing IDEs for programming languages and domain specific languages.

+Rascal builds on top of the [language server protocol](https://microsoft.github.io/language-server-protocol/) for its own services, and for services that
+Rascal programmers create for their own languages. By default Rascal can instantiate an LSP server for VScode, but there is nothing in the way of using other editors that have LSP clients.
 
 To instantiate an IDE for a language implemented using Rascal, use the following steps:
 
 *  Define the grammar for the language.
 *  Define a parse function for the language.
-*  Register the language with Eclipse or VScode.
+*  Register the language with the LSP/VScode, using ((util::LanguageServer))

This functionality is now provided by the [rascal-language-servers](http://github.com/usethesource/rascal-language-servers) project.
