Single Site Install
One of the most common questions we receive is "I only have one site, can I use the WRE, and how do I set it up?"
The answer is, "Of course you can!". We're not sure why we get this question, but the answer is very simple. It doesn't matter whether you have only one site or 1000 sites, you set up the WRE in exactly the same way. The only difference is that you'll only run the addsitescript once (for your first site). There's no custom configuration, there's no reason to disable any of the WRE's complex features.
Trust us, you'll thank us later if you just follow the same procedure everyone else does. Not doing so could mean that your upgrade path for the WRE will break. In addition, you may have only one site now, but that doesn't mean you won't have more in the future!
