Thanks for using our product.
Since most or our Muse users prefer video tutorials, it is the first type of tutorial we make for every product. The video tutorial for the Muse Blog/CMS covers everything from the beginning to the end, even updating to a new version, etc., but we also have a number of online documents and community articles. Furthermore we have included several design samples in the package that can be either directly used or used for further learning.
Regarding the activation: No worries; Each license is valid for up to two domains/subdomains = for one project or end client. We crafted this policy specially with the need of our users for separate testing in mind, so you can use one of the two activations on your test domain and the second on the final domain, without any issues. Of course re-activations or multiple blog/cms instances on either of the two domains are possible and unlimited.
If you have any further questions, feel free to submit a support ticket and we will be here to help.
