+## 🪝 Hook Initialization
+
+| Symbol | Signature | Description |
+|--------|-----------|-------------|
+| `mcpelauncher_preinithook2` | `void(const char* name, void* sym, void* user, void (*callback)(void*, void*))` | Registers a pre-init hook with a callback |
+| `mcpelauncher_preinithook` | `void(const char* name, void* sym, void** orig)` | Registers a pre-init hook and stores original symbol |
+
+---
+
+## 🧬 Hook Management
+
+| Symbol | Signature | Description |
+|--------|-----------|-------------|
+| `mcpelauncher_hook` | `void*(void* sym, void* hook, void** orig)` | Creates and applies a hook for a symbol |
+| `mcpelauncher_hook2` | `void*(void* lib, const char* sym, void* hook, void** orig)` | Creates a hook for a symbol in a specific library |
+| `mcpelauncher_hook2_add_library` | `void(void* lib)` | Adds a library to the hook manager |
+| `mcpelauncher_hook2_remove_library` | `void(void* lib)` | Removes a library from the hook manager |
+| `mcpelauncher_hook2_delete` | `void(void* hook)` | Deletes a hook instance |
+| `mcpelauncher_hook2_apply` | `void()` | Applies all registered hooks |
+
+---
+
+## 🧵 Memory Patching
+
+| Symbol | Signature | Description |
+|--------|-----------|-------------|
+| `mcpelauncher_patch` | `void*(void* address, void* data, size_t size)` | Patches memory at a given address |
+| *(Apple ARM64 only)* | Uses `pthread_jit_write_protect_np` and `sys_icache_invalidate` for JIT-safe patching |
+

+
+## 📦 Dynamic Library Handling
+
+| Symbol | Description |
+|--------|-------------|
+| `mcpelauncher_host_dlopen` | Wrapper for `dlopen` |

+
+## 🔁 Symbol Relocation
+
+| Symbol | Signature | Description |
+|--------|-----------|-------------|
+| `mcpelauncher_relocate` | `void(void* handle, const char* name, void* hook)` | Relocates a single symbol |
+| `mcpelauncher_relocate2` | `void(void* handle, size_t count, hook_entry* entries)` | Relocates multiple symbols |
+| `mcpelauncher_load_library` | `void(const char* name, size_t count, hook_entry* entries)` | Loads a library and applies hooks |
+| `mcpelauncher_unload_library` | `void(void* handle)` | Unloads a previously loaded library |
+
+---
+
+## 📚 Data Structures
+
+```cpp
+struct hook_entry {
+    const char* name;
+    void* hook;
+};
+```
+
+Used for batch relocation and library loading.

+Would you like this turned into documentation for developers, or maybe a visual diagram of how the hook system works?
