Matt-Cloud Drive - New
Matt-Cloud Drive? How is this different from Matt Drive? Well that is a great question hypothetical homie that is reading this guide. Matt-Drive was the original cloud storage site I had set up. It recently crapped the shed and the online office suite stopped saving when editing in the browser. After being unable to fix this in a reasonable amount of time, I considered that it might take less time to just create a new Seafile instance that is running a newer version that is working with Onlyoffice and also works with Authelia for login. I was finally able to accomplish this, and this lives at https://drive.matt-cloud.com. I managed to get the configuration working such that logging in with username and password works the same as logging in with Matt-Cloud SSO - thus the pedantic name difference. Matt Drive was just Matt's cloud drive when I started slapping shit together. Matt-Cloud Drive is the new hotness that logs in with the Matt-Cloud SSO. Unfortunately, since nobody is paying me for this, I am not gonna go through and transfer anyone else's stuff over. Matt dtive is now down and I'm not sure if I still have the data, so I hope you grabbed what you needed while it was still up.
Anyway, this thing works the same as it used to more-or-less, just that now you don't need to use your username and password in the browser, assuming you've signed into Matt-Cloud in general. There are desktop and mobile clients, and that login works with just your Matt-Cloud username and password. There is also a new thing called SeaDocs, which is a bit like OneNote, though I have not messed with it a whole lot yet. I thought it might be a replacement for OnlyOffice, but it only opens SeaDocs files, so instead of replacing a feature I added one; neat.
I will add some fresh screenshots here.
Login Page. Note the Single Sign-On login; that will log you right in if you're already logged into Matt-Cloud.
Home Page after login. To add a library, there is a drop-down menu chevron right next to My Libraries that was unintuitive enough to me that it took a minute to figure it out, so I thought I would mention that here. 
New Empty Default Library. Note the options for editable file types here. You can also drag-and-drop into the browser.
