+        
+        This toolchain is designed to compile the necessary libraries for iOS to run
+        your application and manage the creation of the Xcode project.
+        
+        We do not provide any binary distributions of this toolchain.
+        You do need to compile it at least once before creating your Xcode project.
+        
+        The toolchain supports:
+        
+        - iPhone Simulator (x86_64)
+        - iPhone / iOS (armv7 and arm64)
+        
+        These recipes are not ported to the new toolchain yet:
+        
+        - lxml
+        
+        
+        ## Installation & requirements
+        
+        Before we start, we strongly advise to use a Python virtual environment to install Python packages.
+        
+              python3 -m venv venv
+              . venv/bin/activate
+        
+        Install [Kivy for iOS from PyPI](https://pypi.org/project/kivy-ios) with pip like any Python package.
+        
+              pip3 install kivy-ios
+        
+        Additionally you would need few system dependencies and configuration.
+        
+        - Xcode 10 or above, with an iOS SDK and command line tools installed:
+        
+              xcode-select --install
+        
+        - Using brew, you can install the following dependencies:
+        
+              brew install autoconf automake libtool pkg-config
+              brew link libtool
+        
+        ## Using the toolchain
+        
+        Any Python extensions or C/C++ library must be compiled: you need to have what
+        we call a `recipe` to compile it. For example, Python, libffi, SDL2, SDL_image,
+        freetype... all the dependencies, compilation and packaging instructions are
+        contained in a `recipe`.
+        
+        You can list the available recipes and their versions with:
+        
+            $ toolchain recipes
+            audiostream  master
+            click        7.1.2
+            cymunk       master
+            ffmpeg       2.6.3
+            ffpyplayer   v3.2
+            flask        1.1.2
+            freetype     2.5.5
+            hostlibffi   3.2.1
+            hostpython3  3.7.1
+            ios          master
+            itsdangerous 1.1.0
+            jinja2       2.11.2
+            kivy         1.10.1
+            libffi       3.2.1
+            libjpeg      v9a
+            libpng       1.6.26
+            markupsafe   1.1.1
+            moodstocks   4.1.5
+            numpy        1.16.4
+            openssl      1.0.2k
+            photolibrary master
+            pillow       6.1.0
+            plyer        master
+            pycrypto     2.6.1
+            pykka        1.2.1
+            pyobjus      master
+            python3      3.7.1
+            pyyaml       3.11
+            sdl2         2.0.8
+            sdl2_image   2.0.0
+            sdl2_mixer   2.0.0
+            sdl2_ttf     2.0.12
+            werkzeug     1.0.1
+        
+        Then, start the compilation with:
+        
+            $ toolchain build python3 kivy
+        
+        You can build recipes at the same time by adding them as parameters:
+        
+            $ toolchain build python3 openssl kivy
+        
+        Recipe builds can be removed via the clean command e.g.:
+        
+            $ toolchain clean openssl
+        
+        You can install package that don't require compilation with pip::
+        
+            $ toolchain pip install plyer
+        
+        The Kivy recipe depends on several others, like the sdl\* and python recipes.
+        These may in turn depend on others e.g. sdl2_ttf depends on freetype, etc.
+        You can think of it as follows: the kivy recipe will compile everything
+        necessary for a minimal working version of Kivy.
+        
+        Don't grab a coffee, just do diner. Compiling all the libraries for the first
+        time, 3x over (remember, 3 archs, x86_64, armv7, arm64) will take time.
+        
+        For a complete list of available commands, type:
+        
+            $ toolchain
+        
+        ## Create the Xcode project
+        
+        The `toolchain.py` can create the initial Xcode project for you::
+        
+            $ toolchain create <title> <app_directory>
+            $ toolchain create Touchtracer ~/code/kivy/examples/demo/touchtracer
+        
+        Your app directory must contain a main.py. A directory named `<title>-ios`
+        will be created, with an Xcode project in it.
+        You can open the Xcode project using::
+        
+            $ open touchtracer-ios/touchtracer.xcodeproj
+        
+        Then click on `Play`, and enjoy.
+        
+        > *Did you know ?*
+        >
+        > Everytime you press `Play`, your application directory will be synced to
+        > the `<title>-ios/YourApp` directory. Don't make changes in the -ios
+        > directory directly.
+        
+        
+        ## Configuring your App
+        
+        You can configure and customize your app in various ways:
+        
+        - Set the icon and launch images in XCode. Note that XCode requires that you
+           specify these assests per device or/and iOS version.
+        
+        - When you first build your XCode project, a 'main.m' file is created in your
+           XCode project folder. This file configures your environment variables and
+           controls your application startup. You can edit this file to customize your
+           launch environment.
+        
+        - Kivy uses SDL, and as soon as the application starts the SDL main, the launch
+           image will disappear. To prevent that, you need to have 2 files named
+           `Default.png` and `Default-Landscape.png`, and put them
+           in the `Resources` folder in Xcode (not in your application folder)
+        
+        > *Did you know ?*
+        >
+        > If you wish to restrict your apps orientation, you should do this via
+        > the 'export_orientation' function in 'main.m'. The XCode orientation
+        > settings should be set to support all.
+        
+        
+        ## Using recipes
+        
+        Recipes are used to install and compile any libraries you may need to use. These
+        recipes follow the same format as those used by the
+        [Python-for-Android](https://github.com/kivy/python-for-android) sister project.
+        Please refer to the
+        [recipe documentation](https://python-for-android.readthedocs.io/en/latest/recipes/)
+        there for more detail.
+        
+        
+        ## Reducing the application size
+        
+        If you would like to reduce the size of your distributed app, there are a few
+        things you can do to achieve this:
+        
+        - Minimize the `build/pythonX/lib/pythonXX.zip`: this contains all the python
+           modules. You can edit the zip file and remove all the files you'll not use
+           (reduce encodings, remove xml, email...)
+        
+        - Go to the settings `panel` > `build`, search for `"strip"` options, and
+           triple-check that they are all set to `NO`. Stripping does not work with
+           Python dynamic modules and will remove needed symbols.
+        
+        - By default, the iOS package compiles binaries for all processor
+           architectures, namely x86_64, armv7 and arm64 as per the guidelines from
+           Apple. You can reduce the size of your ipa significantly by removing the
+           x86_64 architecture as they are used only for the emulator.
+        
+           The procedure is to first compile/build all the host recipes as is:
+        
+              toolchain build hostpython3
+        
+           Then build all the rest of the recipes using --arch=armv7 --arch=arm64
+           arguments as follows:
+        
+              toolchain build python3 kivy --arch=armv7 --arch=arm64
+        
+           Note that these packages will not run in the iOS emulators, so use them
+           only for deployment.
+        
+        ## Usage
+        
+        ```
+        toolchain <command> [<args>]
+        
+        Available commands:
+            build         Build a recipe (compile a library for the required target
+                            architecture)
+            clean         Clean the build of the specified recipe
+            distclean     Clean the build and the result
+            recipes       List all the available recipes
+            status        List all the recipes and their build status
+        
+        Xcode:
+            create        Create a new xcode project
+            update        Update an existing xcode project (frameworks, libraries..)
+            launchimage   Create Launch images for your xcode project
+            icon          Create Icons for your xcode project
+            pip           Install a pip dependency into the distribution
+            pip3          Install a pip dependency into the python 3 distribution
+        ```
+        
+        ## Development
+        
+        Alternatively, it's also possible to clone the repository and use all the
+        described commands in the above sections.
+        Clone and install it to your local virtual environment:
+        
+            git clone https://github.com/kivy/kivy-ios.git
+            cd kivy-ios/
+            python3 -m venv venv
+            . venv/bin/activate
+            pip install -e .
+        
+        Then use the `toolchain.py` script:
+        
+            python toolchain.py --help
+        
+        
+        ## FAQ
+        
+        ### Fatal error: "stdio.h" file not found
+        
+        You need to install the Command line tools: `xcode-select --install`
+        
+        ### You must build with bitcode disabled (Xcode setting ENABLE_BITCODE should be No).
+        
+        We don't support bitcode. You need to go to the project setting, and disable bitcode.
+        
+        ### You don't have permissions to run
+        
+        It is due to invalid archs, search for them and check it. Maybe you
+        targetted a simulator but have only armv7/arm64. Maybe you want to target
+        your iPad but it as only x86_64.
+        
+        ### Why does the python multiprocess/subprocess module not work?
+        
+        The iOS application model does not currently support multi-processing in a
+        cross-platform compatible way. The application design focuses on minimizing
+        processor usage (to minimize power consumption) and promotes an
+        [alternative concurrency model](https://developer.apple.com/library/archive/documentation/General/Conceptual/ConcurrencyProgrammingGuide/Introduction/Introduction.html).
+        
+        If you need to make use of multiple processes, you should consider using
+        [PyObjus](https://github.com/kivy/pyobjus) to leverage native iOS
+        functionals for this.
