 ## Quick Start
 
+Rust analyzer builds on stable Rust >= 1.29.0.

 ```
+# run tests
 $ cargo test
-$ cargo parse < crates/libsyntax2/src/lib.rs

-## Trying It Out
+# show syntax tree of a Rust file
+$ cargo run --package ra_cli parse < crates/ra_syntax/src/lib.rs

-It's better to remove existing Rust plugins to avoid interference.
-Warning: plugin is not intended for general use, has a lot of rough
-edges and missing features (notably, no code completion). That said,
-while originally libsyntax2 was developed in IntelliJ, @matklad now
-uses this plugin (and thus, libsytax2) to develop libsyntax2, and it
-doesn't hurt too much :-)
-

-### Features:
-
-* syntax highlighting (LSP does not have API for it, so impl is hacky
-  and sometimes fall-backs to the horrible built-in highlighting)
-
-* commands (`ctrl+shift+p` or keybindings)
-  - **Show Rust Syntax Tree** (use it to verify that plugin works)
-  - **Rust Extend Selection** (works with multiple cursors)
-  - **Rust Matching Brace** (knows the difference between `<` and `<`)
-  - **Rust Parent Module**
-  - **Rust Join Lines** (deals with trailing commas)
+To try out the language server, see [these
+instructions](./editors/README.md). Please note that the server is not
+ready for general use yet. If you are looking for a Rust IDE that
+works, use [IntelliJ
+Rust](https://github.com/intellij-rust/intellij-rust) or
+[RLS](https://github.com/rust-lang-nursery/rls). That being said, the
+basic stuff works, and rust analyzer is developed in the rust analyzer
+powered editor.
 
-* **Go to symbol in file**
-
-* **Go to symbol in workspace**
-  - `#Foo` searches for `Foo` type in the current workspace
-  - `#foo#` searches for `foo` function in the current workspace
-  - `#Foo*` searches for `Foo` type among dependencies, excluding `stdlib`
-  - Sorry for a weired UI, neither LSP, not VSCode have any sane API for filtering! :)
-
-* code actions:
-  - Flip `,` in comma separated lists
-  - Add `#[derive]` to struct/enum
-  - Add `impl` block to struct/enum
-  - Run tests at caret
-
-* **Go to definition** ("correct" for `mod foo;` decls, index-based for functions).
