+## Prerequire
+
+* for building
+    * LDC2 (>=1.24.0)
+    * Xcode (>=12.3)
+        * Apple account registration for App signing.
+    * Git
+    * curl

+    * iOS Simulator
+
+## Instructions
+
+### Download and build libraries
+
+Change directory to `libs/` and run follow shells.
+
+1. `00_copy_druntimes.sh`
+    * Copy druntime and phobos library files from LDC2 directory.
+1. `01_download-and-build-SDL2.sh`
+    * Download a SDL2 source tarball and build using iOS configuration.
+1. `02_download-and-build-SDL2_mixer.sh`
+    * Download a SDL2_mixer source tarball and build using iOS configuration.
+1. `03_build-bindbc-sdl.sh`
+    * Update bindbc-sdl from Github repository and build with patching to dub.sdl.
+
+### Build tt.app
+
+Change directory to this file directory.
+
+1. `build-ios.sh`
+    * Compile `libtt.a` object files.
+    * Merge dependency libraries.
+    * Build `project/build/tt.app` for iPhone simulator.
+1. Build for real iOS devices using Xcode.
