 See [Releases](https://github.com/dmy/elm-raspberry-pi/releases/) to install specific older versions.
 
 Built and tested on Raspberry Pi 4 Model B with Raspbian GNU/Linux 10 (32 bits).
 
 *Please report any success or failure on others ARM platforms.*
 
+## Node.js
+
+For tools like elm-test, you will need a more recent version of Node.js.
+The following command will currently install Node.js v11:
+```
+sudo apt-get update
+curl -sL https://deb.nodesource.com/setup_11.x | sudo bash -
+sudo apt-get install -y nodejs
+```
+Is is advised to configure npm to store packages in a user directory.
+Add to `~/.bashrc`:
+```
+NPM_PACKAGES="$HOME/.npm-packages"
+PATH="$NPM_PACKAGES/bin:$PATH"
+# Unset manpath so we can inherit from /etc/manpath via the `manpath` command
+unset MANPATH  # delete if you already modified MANPATH elsewhere in your configuration
+MANPATH="$NPM_PACKAGES/share/man:$(manpath)"
+```
+and run
+```
+npm config set prefix ~/.npm-packages
+```
+Then logout/login.
+
+## elm-test
+You can install `elm-test` globally:
+```
+npm install -g elm-test
+```
+But it won't run without an `elmi-to-json` binary suitable for the platform,
+which is not available upstream, so you have to copy manually the one provided by this release
+to the expected location:
+```
+cp /usr/local/bin/elmi-to-json $(npm config get prefix)/lib/node_modules/elm-test/node_modules/elmi-to-json/bin/elmi-to-json
+```
+
 ## Known issues
 * Because [SMP is disabled by mistake in ghc on ARMv7](https://gitlab.haskell.org/ghc/ghc/issues/13007), the compiler will use a single core.
