 Mods are loaded during client startup from the mod load paths by running
 the `init.lua` scripts in a shared environment.
 
+In order to load client-side mods in a world, the following conditions need to be satisfied:
+
+1) `$path_user/minetest.conf` contains the setting `enable_client_modding = true`
+
+2) The client-side mod located in `$path_user/clientmods/<modname>` is added to
+    `$path_user/clientmods/mods.conf` as `load_mod_<modname> = true`.
+
+Note: Depending on the remote server's settings, client-side mods might not
+be loaded or have limited functionality. See setting `csm_restriction_flags` for reference.
