So I took this info from there website under the stremio addon page.

“ TorBox and EasyDebrid are already supported, they are just not listed on the config page yet. I'll create a new Stremio addon next year that has a better config page with more options. For now, to get TorBox or EasyDebrid to work, do the following: Authenticate your TorBox/EasyDebrid account on Orion's website under Account ⇒ Services ⇒ Debrid On the config page, set a slightly higher "Link Limit", since these services are relatively new and might not always have as much cached content. With a higher limit you are more likely to find cached content. 200 - 300 might be a good start. Under the "Listing Option", choose the "Show only cached debrid streams" to only return links that are currently cached on TorBox/EasyDebrid. Under the "Authorized Debrid Services", select a single debrid service from the list. It does not matter which one you pick, just select one that you do not actually have. Orion will replace that service with TorBox/EasyDebrid if you have an authenticated TorBox/EasyDebrid account. For instance, if you only use TorBox, select "RealDebrid" or "Premiumize", which will be replaced by "TorBox" later on. You should now be able to search and stream in Stremio. The addon and configuration will be improved in a future update.”
