Your Personal Cloud: OwnCloud on Raspberry Pi

Guild Members would you like to ditch Dropbox, opt out of OneDrive, and ignore iCloud? You can create your own personal cloud storage device with a Raspberry Pi, an external hard drive, and FOSS software called OwnCloud. Walk through installation and configuration of your own cloud storage server as well as desktop and mobile applications that let you access your files seamlessly alongside local device storage, both at your home/office and from public internet. Required to play along at home: rPi 3B or 4 with a network connection (wired is highly recommended), SD card with latest Raspian image installed, external hard drive formatted with ext4 file system. For outside (internet) access, VPN or ability to port-forward through your firewall; I will cover getting a LetsEncrypt SSL certificate for the ownCloud server.
