+# Known incompatibilities with Valve's VScript
+
+Some features are not available in Mapbase's implementation of VScript, although some may be available in the future.
+
+* Most of the global functions (e.g. `SpawnEntityFromTable`) are not yet available because many of them are game-speciic.
+* Some singletons like `Convars` or `NetProps` are not available. (`Entities` *is* available)
+* It is currently not possible to use in-game documentation methods, such as `script_help`.
+
+# Documentation
+
 A lot of the documentation for VScript on the VDC applies to Mapbase, but Mapbase also extends the VScript support in various ways, mostly to make it able to operate upon NPCs and other Source 2013/Half-Life 2 conventions. Those changes are documented below.
