If you have gone through the setup on DragonTeach, you will now have a WordPress install you can use. Congratulations! Now what?
WordPress has a wealth of information and howtos on their web site. Check it out here… https://wordpress.org/support/article/new-to-wordpress-where-to-start. On this page, on the left side menu, take a look at “Basic Usage” and “Customizing” – these will likely have instructions about how to do most of the things you want to start with.
Where to go from here…
Let start by creating a page. You can take a look at https://wordpress.org/support/article/new-to-wordpress-where-to-start/. If you follow those instructions on your site, you will have a page that can be seen by the world!
You site has a page now, but, it still looks like a default site. WordPress has thousands of themes that can completely change the entire look of your site. Take a look at https://wordpress.org/support/article/using-themes/ to see how to install a new theme and make your site look awesome.
What else can WordPress do? Lots! Additional functionality can be accomplished with plugins. Like the themes, WordPress has a repository of thousands of plugin, each of which can make your site do something new. Everything from adding forms to your pages to backing up. Take a look at https://wordpress.org/support/article/managing-plugins/ for more details.
