The modding toolkit for League of Legends.
League Toolkit is a community-driven ecosystem of libraries, tools, and applications for creating, editing, and distributing League of Legends mods. We maintain the parsers for Riot's file formats, the CLIs that build mods, and the managers that ship them to players.
