+# boilerplate for a  rust language server powered by `tower-lsp` 
+## Introduction
+This repo is a template for `tower-lsp`, a useful github project template which makes writing new language servers easier.
+## Development using VSCode
+1. `pnpm i`
+2. `cargo build`
+3. Open the project in VSCode: `code .`
+4. In VSCode, press <kbd>F5</kbd> or change to the Debug panel and click <kbd>Launch Client</kbd>.
+5. In the newly launched VSCode instance, open the file `examples/test.nrs` from this project.
+6. If the LSP is working correctly you should see syntax highlighting and the features described below should work.
+> **Note**  
+> 
+> If encountered errors like `Cannot find module '/xxx/xxx/dist/extension.js'`
+> please try run command `tsc -b` manually, you could refer https://github.com/IWANABETHATGUY/tower-lsp-boilerplate/issues/6 for more details
+## A valid program in nano rust 
+```rust
+fn factorial(x) {
+    // Conditionals are supported!
+    if x == 0 {
+        1
+    } else {
+        x * factorial(x - 1)
+    }
+}
+
+// The main function
+fn main() {
+    let three = 3;
+    let meaning_of_life = three * 14 + 1;
+
+    print("Hello, world!");
+    print("The meaning of life is...");
+
+    if meaning_of_life == 42 {
+        print(meaning_of_life);
+    } else {
+        print("...something we cannot know");
+
+        print("However, I can tell you that the factorial of 10 is...");
+        // Function calling
+        print(factorial(10));
+    }
+}
+```
+## Features
+This repo use a language `nano rust` which first introduced by [ chumsky ](https://github.com/zesterer/chumsky/blob/master/examples/nano_rust.rs). Most common language feature has been implemented, you could preview via the video below.
