One or more techniques and/or systems are provided for generating a bundle package, digitally signing the bundle package, selectively disturbing the bundle package, and/or indexing one or more resource packages retrieved from the bundle package. That is, a bundle package (e.g., an application or game bundle package) comprises one or more app packages comprising application code configured to execute on various computing environments (e.g., operating systems, processors, etc.). The bundle package may comprise one or more resource packages comprising supplemental data used to provide optional user experience functionality for the application (e.g., French language support, high resolution textures, a gaming pad support, etc.). In this way, a client device may selectively download portions of the bundle package that may be relevant, which may mitigate download bandwidth, storage space, or resources otherwise used to obtain unnecessary portions of the bundle package (e.g., a tablet device may merely download low resolution textures).
