This may be a bit basic but of course you need to

1. Install DNN
2. Install 2sxc in DNN (go to Host > Extensions > Install...)

Whenever you install 2sxc on a DNN portal, or when you create a new portal on a DNN with 2sxc installed, 2sxc will automatically ask you if you want to install this. So the standard procedure is:

1. Add a Content module to the page
2. you should now see a dialog asking you to install standard templates, now click on the install button

Todo: add screenshot!

If ever you started by customizing 2sxc Content then the auto-install won't appear any more. You can still import this package manually, like this:

1. First, download the latest package
2. On a Content module, go to the 2sxc Administration (2sxc-toolbar with gear-icon, or dnn-pencil-button > Admin)
3. There, go to the tab App
4. In that tab, click on "Import parts" - which imports a package into the existing package
5. Now select the package you downloaded before, and install
