 In order to run the Graasp backend, it requires:
 
-- Node version 24
-- NPM version 11
-- Yarn (can be installed through [`nvm`](https://github.com/nvm-sh/nvm))
+- [Mise](https://mise.jdx.dev) (tool manager)
 - [Docker](https://docs.docker.com/get-docker/) or [Podman](https://podman.io/): Docker is not necessary, it is possible to install everything locally. However it is strongly recommended to use the Docker installation guide.
 
+Mise will automatically install the correct version of node and pnpm. You should only have to do:
+`mise install`. You might have to trust the workspace with `mise trust` first.
+Then when you call `pnpm i` it will ask you to download pnpm via corepack. Accept.

 ## Recommended Tools
 
-- [NVM](https://github.com/nvm-sh/nvm) or [Volta (recommended)](https://volta.sh/) : CLI to manage multiple versions of NodeJs and NPM.
 - [Postman](https://www.postman.com) : Application to explore and test your APIs.
 - [Starship](https://starship.rs/): A shell prompt enhancer that shows you the current git branch nvm version and package version, very useful for quick look at your environment (works on all shells and is super fast), requires you to use a [NerdFont](https://www.nerdfonts.com/)
 - [VS Code](https://code.visualstudio.com) : IDE to manage the database and make changes to the source code.
