 # 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.

+### Preview and test extension locally with `VsCode`
+1. Make sure all dependency are installed.
+2. Make sure the `nrs-language-server` is under your `PATH`
+3. `pnpm run package`
+4. `code --install-extension nrs-language-server-${version}.vsix`, the `version` you could inspect in file system.
+5. Restart the `VsCode`, and write a minimal `nano rust` file, then inspect the effect.
+
+For other editor, please refer the related manual, you could skip the `VsCode` part.
