WordPress is a publishing system. Posts are dated and listed. Pages are standing documents. The theme is how they look. Plugins add jobs the theme should not own.
Your first week
Set permalinks. Create a page and a post. Put a menu in the header. Install nothing until that feels boring.
Mental model
Content in the database. Design in the theme. Extra features in plugins. Mixing all three in a page builder is how teams get stuck.
Next
Backups, HTTPS, and a host that restores. Then write. The software is ready long before the calendar is.
