 ## Enabling `rust-analyzer`
 
-`rust-analyzer` support is provided, but it depends on your editor
-whether it's enabled by default. (RLS support is not provided)
-
-To enable `rust-analyzer`, you'll need to make Cargo build the project
-with the `exercises` feature, which will automatically include the `exercises/`
-subfolder in the project. The easiest way to do this is to tell your editor to
-build the project with all features (the equivalent of `cargo build --all-features`).
-For specific editor instructions:
-
-- **VSCode**: Add a `.vscode/settings.json` file with the following:
-```json
-{
-    "rust-analyzer.cargo.features": ["exercises"]
-}
-```
-- **IntelliJ-based Editors**: Using the Rust plugin, everything should work
-    by default.
-- _Missing your editor? Feel free to contribute more instructions!_
+Run the command `rustlings lsp` which will generate a `rust-project.json` at the root of the project, this allows [rust-analyzer](https://rust-analyzer.github.io/) to parse each exercise.

 4. If an exercise doesn't make sense to you, feel free to open an issue on GitHub!
    (https://github.com/rust-lang/rustlings/issues/new). We look at every issue,
    and sometimes, other learners do too so you can help each other out!
+5. If you want to use `rust-analyzer` with exercises, which provides features like 
+   autocompletion, run the command `rustlings lsp`. 
 
 Got all that? Great! To get started, run `rustlings watch` in order to get the first
 exercise. Make sure to have your editor open!"#;
