 ### Building from source
 > We recommend using a version manager as versions change very quickly. You will likely need to switch 
 between multiple Node.js versions based on the needs of different projects you're working on. [NVM on windows](https://github.com/coreybutler/nvm-windows#installation--upgrades) on Windows and [nvm](https://github.com/nvm-sh/nvm) on Linux/macOS are pretty good choices. Also recommended nodejs version is 16.15.0 LTS.
