 Windows (may be called apps in other window managers) can be developed in any language, though it is easiest to do so in Rust because the `ming-wm-lib` crate can be used.

+Though some windows (windows = apps, in ming-wm terminology) are built-in to the ming binary (eg, the help and about windows), most windows are separate binaries. This makes it possible for windows to be written in any language (though it will be far easier to write on in Rust because of the `ming-wm-lib` crate), and ensures that errors / crashes in the windows don't result in the window manager also crashing.
+
+Some good examples are in `src/bin`. Another good example is the [Koxinga web browser](https://github.com/stjet/koxinga). All of these are written in Rust, though examples of windows written in other languages will be created later.
+
+## Window Binary Discovery
+
+The window manager automatically searches for window binaries and adds them to the start menu if:
+
+- The binary is in the same directory as the ming binary.
+- The binary file name is in the form `ming<Category>_<App_Name>`. Where `<Category>` is a category name in the start menu. For example, the Terminal binary is named `mingUtils_Terminal`.
+
+## Inter-Process Communication (IPC)
+
+Since the windows and the window manager are separate binaries, they need some way to communicate. This is achieved by the window manager spawning the window binary with piped stdout and piped stdin. See `src/proxy_window_like.rs` and `ming-wm-lib/src/ipc.rs` for more information.
+
+The serialization format is in `ming-wm-lib/src/serialize.rs`. Make sure any newlines (`\n`) in strings are removed before/after serializations. When doing IPC, the window manager assumes the response to a query is one line, so if a newline is present, it will fail to parse the response.

+
+## Tips
+
+- For windows that are separate binaries, the Elm Architecture obviously cannot be enforced (unless the window is written in Rust and uses the `ming-wm-lib`. However, the design of the IPC and the nature of the window manager being keyboard-driven makes it so using the Elm Architecture is highly recommended.
+- Since the window manager currently queries and reads the responses to/from window binaries in the main thread, while the response is being waited for, the window manager is "frozen". Therefore, time-consuming tasks (>1 second) should not be done in the main thread, but rather a separate thread. For example, the ming-wm audio player (`src/bin/audio_player.rs`) does the time-consuming process of reading audio files in a separate thread to not hold up the window manager, and provide quick responses.

+## Usage
+
+Each square has a two-digit number on it. Type that number to place a piece on that square. If only one digit is typed, the backspace key can be hit to clear that digit. Black goes first.
+
+Once the game is over, the winner (if it is not a tie) will be announced, and any key can be hit to play again.
+
+There is currently no computer opponent, so this is a pass-and-play game.
