You also need NodeJS installed locally : we **strongly** advise to install [Node Version Manager](https://github.com/nvm-sh/nvm) and use the latest LTS version of Node (check that your local version matches with the one used in the Dockerfile).
The API will run inside a docker container, **but** the install itself is made outside the container, because during development we need tools that need to be available locally (eg. ESLint or Prettier with fix-on-save).
