Google Sites is where you are at. Google Sites allows you to create your own website. Be sure you are on the new Google Sites as it is easier to make adjustments and manage the site.
You can add directly to this website, you can create documents that are easy to update. If you visit my resource page, you will see it is set up as a table. That is using a Google Doc to create a table and then added to the site. In order to update it, I update the Google Doc and it automatically updates on the website.
Through my Chrome Academy course, I learned the best way to start a Google Site is through Drive. Go to New, click More and then Sites. To learn more about Google Sites, choose the length of video below to watch.
