 For Solaris based OSes, `${CMAKE_SYSTEM_NAME}` isn't properly set on CMake (it's set to i686 on AMD64), you may find issues when building OpenSSL from `openssl-cmake`.
 
+## iOS
+
+iOS has a dedicated build script, we **highly** recommend using that instead of doing anything else, we don't support any other configuration than the one present in said build script.
+
+To build, it's simply as easy as doing
+```sh
+chmod +x .ci/ios/build.sh

 ## HaikuOS
 
 It's recommended to do a `pkgman full-sync` before installing. See [HaikuOS: Installing applications](https://www.haiku-os.org/guides/daily-tasks/install-applications/). Sometimes the process may be interrupted by an error like "Interrupted syscall". Simply firing the command again fixes the issue. By default `g++` is included on the default installation.
