 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
+.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.

-- `--config/-c`: Specify alternate configuration file.
-- `--fullscreen/-f`: Use fullscreen.
-- `--help/-h`: Display help.
-- `--game/-g <path>`: Alternate way to specify what to load, overrides. However let it be noted that arguments that use `-` will be treated as options/ignored, if your game, for some reason, starts with `-`, in order to safely handle it you may need to specify it as an argument.
-- `--multiplayer/-m`: Specify multiplayer options.
-- `--program/-p`: Specify the program arguments to pass (optional).
-- `--user/-u <number>`: Specify the user index.
-- `--version/-v`: Display version and quit.
-- `--input-profile/-i <name>`: Specifies input profile name to use (for player #0 only).
-- `--null-render/-n`: Forces the usage of the "Null" render backend irrespective of settings.
