 === Eclipse IDE
 
-Prerequisites: You have installed the <<rust-analyzer-language-server-binary,`rust-analyzer` binary>>.
-
 Support for Rust development in the Eclipse IDE is provided by link:https://github.com/eclipse/corrosion[Eclipse Corrosion].
-While it currently uses RLS as default, you can successfully configure it so the IDE will use `rust-analyzer` instead.
-To do so, with an Eclipse IDE where Corrosion is installed, just go to __Window > Preferences > Rust__ and edit the __Path to Rust Language Server__ entry to reference the path to `rust-analyzer`.
+If available in PATH or in some standard location, `rust-analyzer` is detected and powers editing of Rust files without further configuration.
+If `rust-analyzer` is not detected, Corrosion will prompt you for configuration of your Rust toolchain and language server with a link to the __Window > Preferences > Rust__ preference page; from here a button allows to download and configure `rust-analyzer`, but you can also reference another installation.
 You'll need to close and reopen all .rs and Cargo files, or to restart the IDE, for this change to take effect.
