# TDLib C++ basic usage examples
TDLib should be prebuilt and installed to local subdirectory `td/`:
```
cd <path to TDLib sources>
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=../example/cpp/td ..
cmake --build . --target install
Also see [building](https://github.com/tdlib/td#building) for additional details on TDLib building.
Then you can build the examples:
cd <path to TDLib sources>/example/cpp
cmake -DCMAKE_BUILD_TYPE=Release -DTd_DIR=<full path to TDLib sources>/example/cpp/td/lib/cmake/Td ..
cmake --build .
Documentation for all available classes and methods can be found at https://core.telegram.org/tdlib/docs.
To run `tdjson_example` you may need to manually copy a `tdjson` shared library from `td/bin` to a directory containing built binaries.
