+IPC
+---
+
+The engine provides a generalized mechanism to enable sharing data between the
+different Lua environments (main, mapgen and async).
+It is essentially a shared in-memory key-value store.
+
+* `minetest.ipc_get(key)`:
+  * Read a value from the shared data area.
+  * `key`: string, should use the `"modname:thing"` convention to avoid conflicts.
+  * returns an arbitrary Lua value, or `nil` if this key does not exist
+* `minetest.ipc_set(key, value)`:
+  * Write a value to the shared data area.
+  * `key`: as above
+  * `value`: an arbitrary Lua value, cannot be or contain userdata.
+
+Interacting with the shared data will perform an operation comparable to
+(de)serialization on each access.
+For that reason modifying references will not have any effect, as in this example:
+```lua
+minetest.ipc_set("test:foo", {})
+minetest.ipc_get("test:foo").subkey = "value" -- WRONG!
+minetest.ipc_get("test:foo") -- returns an empty table
+```
+
+**Advanced**:
+
+* `minetest.ipc_cas(key, old_value, new_value)`:
+  * Write a value to the shared data area, but only if the previous value
+    equals what was given.
+    This operation is called Compare-and-Swap and can be used to implement
+    synchronization between threads.
+  * `key`: as above
+  * `old_value`: value compared to using `==` (`nil` compares equal for non-existing keys)
+  * `new_value`: value that will be set
+  * returns: true on success, false otherwise
+* `minetest.ipc_poll(key, timeout)`:
+  * Do a blocking wait until a value (other than `nil`) is present at the key.
+  * **IMPORTANT**: You usually don't need this function. Use this as a last resort
+    if nothing else can satisfy your use case! None of the Lua environments the
+    engine has are safe to block for extended periods, especially on the main
+    thread any delays directly translate to lag felt by players.
