 -- Steps to generate
 1) copy ./core/distro-configs/LibreOfficeiOS.conf to autogen.input in
    ./ios-arm64, ./ios-arm64-debug, ./ios-simulator
-   Correct as per above, add your local setup (e.g. location of tarballs)
+   Correct as defined in the conf file,
+   add your local setup (e.g. location of tarballs)
 2) run ../core/autogen.sh in ios-arm64, ios-arm64-debug and ios-simulator
 3) run make in ios-arm64, ios-arm64-debug and ios-simulator
    this will generate core/loApp.xcconfig which prepares LO to be compiled
-   and build LOkit is 3 configurations and store the LibreOfficeKit
-   prelinked object in ./core/ios/generated as:
-           LibreOfficeKit-arm64.o
-           LibreOfficeKit-arm64-debug.o
-           LibreOfficeKit-simulator.o
