-Prerequisites
--------------
-Ensure npm is able to build any binary modules it needs to install.
-::
- sudo apt-get install build-essential
+#### Prerequisites
+Ensure npm is able to build any binary modules it needs to install.
+```
+sudo apt-get install build-essential
+```
-Download and installation
--------------------------
-To install Node.js, npm and Node-RED onto a Raspberry Pi, run the following command will that download and install them:
-::
- bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
-
+#### Download and installation

+```
+bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
+```
Due to the limited memory of the Raspberry Pi, you will need to start Node-RED with an additional argument to tell the underlying Node.js process to free up unused memory sooner than it would otherwise.
-::
- node-red-pi --max-old-space-size=256
+```
+node-red-pi --max-old-space-size=256
