 OpenComputers makes an effort to largely emulate the standard library in areas that would usually interact with the host system - that being the I/O library. There are a few differences, which you can look up here: [[differences in the standard libraries|NonstandardLuaLibs]]. Most notably, the debug and package libraries are not available, and `load` only accepts text source files, no binary / pre-compiled Lua programs (for security reasons).
 
+Note that you now need to require all APIs(including the ones below) before you use them.
+For example, instead of simple going "local rs = component.redstone", you now need to require the component API, like so:
+
+```lua
+local component = require("component")
+local rs = component.redstone
+
+--You can of course change the variable name:
+local mycomp = require("component")
+local rs = mycomp.redstone
+```
+The same applies for all other APIs listed below(even Sides and Colors).
