+
+## Overview
+
+libnbt++ is a free C++ library for Minecraft's Named Binary Tag (NBT) file format. It can read and write compressed and uncompressed NBT files and provides a code interface for working with NBT data.
+
+### Version History
+
+- **libnbt++ 1** — Original library (deprecated)
+- **libnbt++ 2** — Rewritten with cleaner API (deprecated)
+- **libnbt++ 3** — Current version used by ProjT Launcher
+
+---
+
+## Usage in ProjT Launcher
+
+libnbt++ is used for:
+
+- **World data** — Reading level.dat and player data
+- **Server data** — Parsing server.dat files
+- **Mod integration** — Processing NBT-based configurations
+- **Backup/export** — Instance data serialization
+
+---
+

+## Build Instructions
+
+### Prerequisites
+
+- C++11 compatible compiler
+- CMake 3.15 or later
+- ZLIB (optional, for compression support)
+
+### Build Steps
+
+```bash
+cd libnbtplusplus
+mkdir build && cd build
+cmake ..
+cmake --build .
+```
+
+### CMake Options
+
+| Option | Description | Default |
+|--------|-------------|---------|
+| `NBT_BUILD_SHARED` | Build shared library | `OFF` |
+| `NBT_USE_ZLIB` | Enable zlib support | `ON` |
+| `NBT_BUILD_TESTS` | Build tests | `ON` |
+
+---
+
+## API Usage
+
+### Reading NBT
+
+```cpp
+#include <nbt_tags.h>
+#include <io/stream_reader.h>
+#include <fstream>
+
+std::ifstream file("level.dat", std::ios::binary);
+nbt::io::stream_reader reader(file, endian::big);
+
+// Read compound tag
+auto result = reader.read_compound();
+nbt::tag_compound& root = result.first;
+std::string name = result.second;
+
+// Access data
+auto& level = root["Data"].as<nbt::tag_compound>();
+std::string levelName = level["LevelName"].as<nbt::tag_string>();
+int32_t gameType = level["GameType"].as<nbt::tag_int>();
+```
+
+### Writing NBT
+
+{% raw %}
+```cpp
+#include <nbt_tags.h>
+#include <io/stream_writer.h>
+#include <fstream>
+
+nbt::tag_compound data;
+data["LevelName"] = nbt::tag_string("My World");
+data["GameType"] = nbt::tag_int(0);  // Survival
+
+std::ofstream file("level.dat", std::ios::binary);
+nbt::io::stream_writer writer(file, endian::big);
+writer.write_tag("", nbt::tag_compound{{"Data", std::move(data)}});
+```
+{% endraw %}
+
+### Working with Lists
+
+```cpp
+// Create a list of strings
+nbt::tag_list items(nbt::tag_type::String);
+items.push_back(nbt::tag_string("item1"));
+items.push_back(nbt::tag_string("item2"));
+
+// Access list
+for (const auto& item : root["Items"].as<nbt::tag_list>()) {
+    std::cout << item.as<nbt::tag_string>().get() << std::endl;
+}
+```
+
+---
+
+## Testing
+
+```bash
+cd libnbtplusplus/build
+ctest -V
+```
