+To install experimental VS Code plugin:
+
+```
+$ cargo install-code
+```
+
+This will run `cargo install --packge ra_lsp_server` to install the
+server binary into `~/.cargo/bin`, and then will build and install
+plugin from `editors/code`. See
+[this](https://github.com/matklad/rust-analyzer/blob/cc76b0d31d8ba013c499dd3a4ca69b37004795e6/crates/tools/src/main.rs#L192)
+for details
+
+It's better to remove existing Rust plugins to avoid interference.
+
+### Features:
+
+* syntax highlighting (LSP does not have API for it, so impl is hacky
+  and sometimes fall-backs to the horrible built-in highlighting)
+  
+* **Go to symbol in workspace** (`ctrl+t`)
+  - `#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! :)
+
+* **Go to symbol in file** (`alt+shift+o`)
+
+* **Go to definition** ("correct" for `mod foo;` decls, approximate for other things).
+
+* commands (`ctrl+shift+p` or keybindings)
+  - **Show Rust Syntax Tree** (use it to verify that plugin works)
+  - **Rust Extend Selection**. Extends the current selection to the
+    encompassing syntactic construct (expression, statement, item,
+    module, etc). It works with multiple cursors. Do bind this command
+    to a key, its super-useful!
+  - **Rust Matching Brace**. If the cursor is on any brace
+    (`<>(){}[]`) which is a part of a brace-pair, moves cursor to the
+    matching brace.
+  - **Rust Parent Module**. Navigate to the parent module of the current module
+  - **Rust Join Lines**. Join selected lines into one, smartly fixing
+    up whitespace and trailing commas.
+  - **Run test at caret**. When cursor is inside a function marked
+    `#[test]`, this action runs this specific test. If the cursor is
+    outside of the test function, this re-runs the last test. Do bind
+    this to a shortcut!
+
+* code actions (use `ctrl+.` to activate).
+
+`<|>` signifies cursor position
+
+- Flip `,`
+
+```
+// before:
+fn foo(x: usize,<|> dim: (usize, usize))
+// after:
+fn foo(dim: (usize, usize), x: usize)
+```
+
+- Add `#[derive]`
+
+```
+// before:
+struct Foo {
+    <|>x: i32
+}
+// after:
+#[derive(<|>)]
+struct Foo {
+    x: i32
+}
+```
+
+- Add `impl`
+
+```
+// before:
+struct Foo<'a, T: Debug> {
+    <|>t: T
+}
+// after:
+struct Foo<'a, T: Debug> {
+    t: T
+}
+
+impl<'a, T: Debug> Foo<'a, T> {
+    <|>
+}
+```
