Here is an example of a page. It is different from a blog article in that it remains in the same place and will be displayed in your site’s navigation menu (depending on your theme). Most people start by writing an “About” page introducing the company to potential visitors to the site. You could write something like this:
Hello! I am an aspiring actor working as a mechanic and this is my blog. I live in Bordeaux, have a fantastic dog called Russell and like vodka and pineapple (as well as whiling away the hours watching the rain).
…or something like this:
123 Thingamabob was founded in 1971 and has been providing high-quality thingies to the public ever since. Based in Saint-Remy-en-Bouzemont-Saint-Genest-et-Isson, 123 Thingamabob has 2,000 employees and manufactures all sorts of great stuff for the local community.
As you are a new WordPress user, you need to go to your dashboard to delete the current page and create new pages with your own content. Have fun!
