Home Page information goes here.
This is your space to put whatever you feel is most important to your site. This can be a short welcome message, perhaps a block with some latest news or upcoming events, or your facebook feed, etc.
As a good rule of thumb, for search engine optimization, you will want at least 200 words on any page on the website. This does include any text you have in your footer and header though. But Google just likes to see pages that have a decent amount of content on them for indexing purposes.
