If you like the mod and would like to play it in your native language, you can translate it by creating a new bundle file (refer to modding wiki for the tag of your country). If there are translation errors, you can fix them by editing the bundle file.
The mod uses bundle-lib, a script which allows to change mod name and description in mods tab in terms of language. You can modify them by adding "mod.commandblocks.name =" and "mod.commandblocks.description =" in the bundle.
Thank you very much!
