 The third phase is about building the Open Event on the server and running it. The steps are very similar to the [Docker installation instructions](INSTALLATION_DOCKER.md) so it is very highly recommended you have a look at it and try to understand the process.
 
-* First you will have to build the server. This process can take some time.
+* First we will set the `SERVER_NAME` config. (See [Docker instructions](INSTALLATION_DOCKER.md) for more info on this)

 * If you haven't added a domain name to your DO droplet and are accessing it through the IP, you might face the problem of not being able to login. This is a Chrome issue
 and may exist in other browsers too (haven't tested). Learn more about it in this [Stack Overflow answer](http://stackoverflow.com/a/27276450/2295672). The only way to solve
 this is by attaching a domain name to your droplet.
+
+* `SERVER_NAME` should be the same as the domain on which the project is running. Don't include http, https, www etc in server name.
+Also don't include the trailing '/' in the domain name.
