Is there downloadable documentation for RouterOS available?
Since my Mikrotik router provides my internet access, it is rather risky to have the only access to the documentation I may need to fix a mis-configuration, on the internet.
It's all old stuff. The only recent one is the (html) wiki.You may find it here i think so https://www.mikrotik.com/documentation
They had it at one point, but I guess they removed it. You could even order a printed version of the collection you had created.There appears to be an extension available for Wiki to convert to e-book or PDF. Other wiki sites sometimes have it available.
Maybe MikroTIk could install it.
