+## Installation

+If you intend to use the [Electron display](http://spencerlyon.com/PlotlyJS.jl/syncplots/#electronplot) or any of its features (recommended) you will need to enter the following at the Julia REPL:
+
+```julia
+using Blink
+Blink.AtomShell.install()
+```
+
+Note that this is a one time process.
