It basically goes like this:

- You mod a specific equipment, which gives a star (*) each time u succeed. After you succeeded 10 times (aka 10*), you can exchange that 10* equipment for a better one at the cost of that 10* equip and some un-modded equips of same type. Modding requires resources, development material AND modding material (new).

- The newly exchanged equip is an improved variant (such as 20.3 no.2 of the usual 20.3). You MAY be able to upgrade that one even further (20.3 no.2 -> 20.3 no.3), by doing the same process, but you'll need to mod those 20.3 no.2 AND exchange some additional 20.3 no.2 (unupgraded) to get the 20.3 no.3.

- What kind of equipment you can mod depends on the assistant ship (ship in 2nd slot, next to Akashi who is currently the flagship). Aoba-class allows u to upgrade 20.3, Fusou-class allows u to upgrade 35.6. Currently I don't know how to upgrade 41cm guns or aircraft, I haven't found any ship that allows u to mod such so it's likely it is not possible yet.

Recommended to only upgrade equipments that are abundant (those you get from dropped ships, such as standard 20.3 and 35.6 cm guns). My recommendation is upgrading those 20.3 as their upgraded variants can't be crafted via normal development, and farming for them is really hard and not worth the effort.

Other than 20.3, you can develop upgraded 14cm twin gun or 35.6 triple Proto, but I highly recommend you NOT to do so. The 14cm Twin is absolutely useless, 35.6 Triple Proto is unneccessary, for now.
