You can protect this page from editing by locking it. If you do so, all blocks will be displayed 'read-only'; changing or deleting a block is not possible.
You may want to lock your page if you plan to publish it to a larger audience. Some functions remain active, e.g. participating in a survey or in a chat. You can unlock the page later permanently or just for yourself, which allows you to edit the page even if it was published already.
You have just created your own simple web page. Everyone who knows the link to this page can read it - and if you do not lock it with a password, also edit it. Share the link with the Share-icon at the top right.
Start with editing this text, or with creating a new text block by clicking on the orange plus icon (top left).
