Step 1: Create your Personal Box
IMPORTANT: All steps are important, but this one defines your storage, it tells Picsium service where to store the files. If you skip this step you won't have any place to store your files and Picsium will NOT WORK!
Install Picsium Box on your computer and create your on-premises cloud storage.
Any of your computers, no matter the configuration should be ok. Except Windows 10 there are no special requirements.
