This is an example page. It is different from your post because it will remain in the same place and will appear in the navigation menu (in most themes). Most start with an About page that introduces them to potential visitors. It can say something like the following:

…or something like this:

The company XYZ was founded in 1971, and has been supplying quality duppets since then. Located in Kristiansund, and employing over 2,000 people who do all kinds of good things for society.
