 ### Installation
 The homebridge-zp plugin obviously needs homebridge, which, in turn needs Node.js.  I've followed these steps to set it up on my macOS server:
 
-- Install the Node.js JavaScript runtime `node`, from its [website](https://nodejs.org).  I'm using v6.10.2 LTS for macOS (x64), which includes the `npm` package manager.
+- Install the Node.js JavaScript runtime `node`, from its [website](https://nodejs.org).  I'm using v6.10.3 LTS for macOS (x64), which includes the `npm` package manager.
 - Make sure `/usr/local/bin` is in your `$PATH`, as `node`, `npm`, and, later, `homebridge` install there.
 - You might want to update `npm` through `sudo npm update -g npm@latest`.  For me, this installs version 4.5.0.
-- Install homebridge following the instructions on [GitHub](https://github.com/nfarina/homebridge#installation).  For me, this installs homebridge version 0.4.19 to `/usr/local/lib/node_modules`.  Make sure to create a `config.json` in `~/.homebridge`, as described.

 - Install the homebridge-zp plugin through `sudo npm install -g homebridge-zp@latest`.
 - Edit `~/.homebridge/config.json` and add the `ZP` platform provided by homebridge-zp, see below.
