# Base IPA Place the unsigned Filza 4.0 IPA here before building: ``` base/FilzaSlop-v1.2.0-unsigned.ipa ``` The build scripts inject `FilzaApplySandboxExt.dylib`, patch the bundle ID and package the app. The base IPA is not committed because it contains Filza's original application payload. You can set `BASE_IPA` to any compatible unsigned Filza IPA instead. The developer build also needs an a-Shell IPA for its command frameworks: ``` ASHELL_IPA=$HOME/Downloads/Terminal.ipa ```
