 ## Known issues
-Obviously this is not an issue free-system. Currently since im doing no mod unloading or loading there could be issues if your servers dont have the exact same mods, or the mods dont properly work right. Please do not swarm mod authors with faults if seamless doesnt play nice with it. ***Its not their fault*** its ***mine***. I will be trying to implement mod unloading and loading switching between servers, just no ETA.

+
+## ModAPI
+I attempted to avoid implementing any modAPI in seamless, but unfortunately, Space Engineers doesn't handle unloading and reloading the same mod without compiling easily. Either I compile the mod every time you switch servers, eventually running into memory issues, or I attempt to unload the mod manually and restart it.
+In both scenarios, unloading static variables are often up to the mod author and sometimes are set to null. On mod load, these variables are not re-instantiated with the default values resulting in many issues. It is way easier for mod authors when needed implement seamless unload and load logic appropriately.
+
+There are two methods you can add to your mods (In the main mod session component class)
+
+private void SeamlessServerLoaded(){}
+private void SeamlessServerUnloaded(){}
+
+Unloaded happens when seamless starts switching, Loaded when seamless is done switching. Seamless patches these methods on mod compilation.
