3. That's it!
## Installation
### VS Code / VSCodium / Cursor / Windsurf
1. Get the latest `.vsix` file from [releases](https://github.com/tact-lang/tact-language-server/releases) from
[VS Code marketplace](https://marketplace.visualstudio.com/items?itemName=tonstudio.vscode-tact)
or from [Open VSX Registry](https://open-vsx.org/extension/tonstudio/vscode-tact)
2. In VS Code:
