@@ -16,3 +16,70 @@ libnbt++2 is a remake of the old libnbt++ library with the goal of making it
 more easily usable and fixing some problems. The old libnbt++ especially
 suffered from a very convoluted syntax and boilerplate code needed to work
 with NBT data.
+
+## Building
+
+This project uses CMake for building. Ensure you have CMake installed.
+
+### Prerequisites
+- C++11 compatible compiler
+- CMake 3.15 or later
+- ZLIB (optional, for compressed NBT support)
+
+### Build Steps
+1. Clone the repository:
+   ```
+   git clone https://github.com/PrismLauncher/libnbtplusplus.git
+   cd libnbtplusplus
+   ```
+
+2. Create a build directory:
+   ```
+   mkdir build
+   cd build
+   ```
+
+3. Configure with CMake:
+   ```
+   cmake ..
+   ```
+   Options:
+   - `NBT_BUILD_SHARED=OFF` (default): Build static library
+   - `NBT_USE_ZLIB=ON` (default): Enable zlib support
+   - `NBT_BUILD_TESTS=ON` (default): Build tests
+
+4. Build:
+   ```
+   cmake --build .
+   ```
+
+5. Install (optional):
+   ```
+   cmake --install .
+   ```
+
+## Usage
+
+Include the headers and link against the library.
+
+### Example
+```cpp
+#include <nbt_tags.h>
+#include <fstream>
+#include <iostream>
+
+int main() {
+    // Read an NBT file
+    std::ifstream file("example.nbt", std::ios::binary);
+    nbt::tag_compound root = nbt::io::read_compound(file).first;
+
+    // Access data
+    std::cout << root["some_key"].as<nbt::tag_string>() << std::endl;
+
+    return 0;
+}
+```
