This is a sample page. It is different from an entry because it stays fixed in one place and will be displayed in the navigation of your site (in most themes). Most people start with a About page, which introduces them to potential site visitors. It could be something like this:

Hello! I’m a courier for the day, an aspiring actor at night, and this is my blog. I live in Madrid, I have a dog called Duque and I like the pina coladas (and I catch a shower)

…or something like that:

XYZ was founded in 1971 and has been offering quality “stuff” to the public ever since. Located in Madrid, XYZ employs more than 2,000 people and does all kinds of surprising things for the community of Madrid.
