# IDE Setup Guide for PSS Language Server

This guide is aimed to help you setup the PSS Language server for your favourite IDE.

> [!NOTE]

> Before integrating with any IDE (Other than VS Code), please ensure you have installed the language server globally by running:
>
>```bash
> npm install -g pss-langserver
>```
>
> This installs the `pss-langserver` command, which you can start using the `--stdio` option (among others).
>
> Before running the above command, ensure NodeJS is installed on your system.
> If not, just get it [from here](https://nodejs.org/en/download)
