 This extension uses the _Language Server Protocol_ to communicate with Visual Studio Code, which is an open protocol that allows the development of a common implementation - called a __language server__ - that can communicate with different IDEs. This implementation is stored in the [Cucumber Language Server](https://github.com/cucumber/language-server) and the underlying [Cucumber Language Service](https://github.com/cucumber/language-service). Let's integrate local versions of each into our extension so we can modify them.

 ### Check everything is working
 
 A nice way to check you are using the local language server implementations is to modify the snippet templates that generate step definitions for undefined steps. You will find these templates assigned to `defaultSnippetTemplate` in each of the ['\<language>Language.ts' files](https://github.com/cucumber/language-service/tree/main/src/language) of the Language Service, where each `<language>` is a programming language in which you can write compatible step definitions. Preferably, use a language you are comfortable with.
