+# Example: `ghostty-vt` C Key Encoding
+
+This example demonstrates how to use the `ghostty-vt` C library to encode key
+events into terminal escape sequences.
+
+This example specifically shows how to:
+
+1. Create a key encoder with the C API
+2. Configure Kitty keyboard protocol flags (this example uses KKP)
+3. Create and configure a key event
+4. Encode the key event into a terminal escape sequence
+
+The example encodes a Ctrl key release event with the Ctrl modifier set,
+producing the escape sequence `\x1b[57442;5:3u`.
+
+## Usage
+
+Run the program:
+
+```shell-session
+zig build run
+```

+# Example: `ghostty-vt` C Program
+
+This contains a simple example of how to use the `ghostty-vt` C library
+with a C program.
+
+This uses a `build.zig` and `Zig` to build the C program so that we
+can reuse a lot of our build logic and depend directly on our source
+tree, but Ghostty emits a standard C library that can be used with any
+C tooling.
+
+## Usage
+
+Run the program:
+
+```shell-session
+zig build run
+```

+/** @defgroup allocator Memory Management
+ *
+ * libghostty-vt does require memory allocation for various operations,
+ * but is resilient to allocation failures and will gracefully handle
+ * out-of-memory situations by returning error codes.
+ *
+ * The exact memory management semantics are documented in the relevant
+ * functions and data structures.
+ *
+ * libghostty-vt uses explicit memory allocation via an allocator
+ * interface provided by GhosttyAllocator. The interface is based on the
+ * [Zig](https://ziglang.org) allocator interface, since this has been
+ * shown to be a flexible and powerful interface in practice and enables
+ * a wide variety of allocation strategies.
+ *
+ * **For the common case, you can pass NULL as the allocator for any
+ * function that accepts one,** and libghostty will use a default allocator.
+ * The default allocator will be libc malloc/free if libc is linked. 
+ * Otherwise, a custom allocator is used (currently Zig's SMP allocator)
+ * that doesn't require any external dependencies.
+ *
+ * ## Basic Usage
+ *
+ * For simple use cases, you can ignore this interface entirely by passing NULL
+ * as the allocator parameter to functions that accept one. This will use the
+ * default allocator (typically libc malloc/free, if libc is linked, but
+ * we provide our own default allocator if libc isn't linked).
+ *
+ * To use a custom allocator:
+ * 1. Implement the GhosttyAllocatorVtable function pointers
+ * 2. Create a GhosttyAllocator struct with your vtable and context
+ * 3. Pass the allocator to functions that accept one
+ *
+ * @{
+ */
+
+/**
+ * Function table for custom memory allocator operations.
+ * 
+ * This vtable defines the interface for a custom memory allocator. All
+ * function pointers must be valid and non-NULL.
+ *
+ * @ingroup allocator
+ *
+ * If you're not going to use a custom allocator, you can ignore all of
+ * this. All functions that take an allocator pointer allow NULL to use a
+ * default allocator.
+ *
+ * The interface is based on the Zig allocator interface. I'll say up front
+ * that it is easy to look at this interface and think "wow, this is really
+ * overcomplicated". The reason for this complexity is well thought out by
+ * the Zig folks, and it enables a diverse set of allocation strategies
+ * as shown by the Zig ecosystem. As a consolation, please note that many
+ * of the arguments are only needed for advanced use cases and can be
+ * safely ignored in simple implementations. For example, if you look at 
+ * the Zig implementation of the libc allocator in `lib/std/heap.zig`
+ * (search for CAllocator), you'll see it is very simple.
+ *
+ * We chose to align with the Zig allocator interface because:
+ *
+ *   1. It is a proven interface that serves a wide variety of use cases
+ *      in the real world via the Zig ecosystem. It's shown to work.
+ *
+ *   2. Our core implementation itself is Zig, and this lets us very
+ *      cheaply and easily convert between C and Zig allocators.
+ *
+ * NOTE(mitchellh): In the future, we can have default implementations of
+ * resize/remap and allow those to be null.

+/** @defgroup key Key Encoding
+ *
+ * Utilities for encoding key events into terminal escape sequences,
+ * supporting both legacy encoding as well as Kitty Keyboard Protocol.
+ *
+ * ## Basic Usage
+ *
+ * 1. Create an encoder instance with ghostty_key_encoder_new()
+ * 2. Configure encoder options with ghostty_key_encoder_setopt().
+ * 3. For each key event:
+ *    - Create a key event with ghostty_key_event_new()
+ *    - Set event properties (action, key, modifiers, etc.)
+ *    - Encode with ghostty_key_encoder_encode()
+ *    - Free the event with ghostty_key_event_free()
+ *    - Note: You can also reuse the same key event multiple times by
+ *      changing its properties.
+ * 4. Free the encoder with ghostty_key_encoder_free() when done
+ *
+ * ## Example
+ *
+ * @code{.c}
+ * #include <assert.h>
+ * #include <stdio.h>
+ * #include <ghostty/vt.h>
+ * 
+ * int main() {
+ *   // Create encoder
+ *   GhosttyKeyEncoder encoder;
+ *   GhosttyResult result = ghostty_key_encoder_new(NULL, &encoder);
+ *   assert(result == GHOSTTY_SUCCESS);
+ * 
+ *   // Enable Kitty keyboard protocol with all features
+ *   ghostty_key_encoder_setopt(encoder, GHOSTTY_KEY_ENCODER_OPT_KITTY_FLAGS, 
+ *                              &(uint8_t){GHOSTTY_KITTY_KEY_ALL});
+ * 
+ *   // Create and configure key event for Ctrl+C press
+ *   GhosttyKeyEvent event;
+ *   result = ghostty_key_event_new(NULL, &event);
+ *   assert(result == GHOSTTY_SUCCESS);
+ *   ghostty_key_event_set_action(event, GHOSTTY_KEY_ACTION_PRESS);
+ *   ghostty_key_event_set_key(event, GHOSTTY_KEY_C);
+ *   ghostty_key_event_set_mods(event, GHOSTTY_MODS_CTRL);
+ * 
+ *   // Encode the key event
+ *   char buf[128];
+ *   size_t written = 0;
+ *   result = ghostty_key_encoder_encode(encoder, event, buf, sizeof(buf), &written);
+ *   assert(result == GHOSTTY_SUCCESS);
+ * 
+ *   // Use the encoded sequence (e.g., write to terminal)
+ *   fwrite(buf, 1, written, stdout);
+ * 
+ *   // Cleanup
+ *   ghostty_key_event_free(event);
+ *   ghostty_key_encoder_free(encoder);
+ *   return 0;
