### Building from source
-Still here? To build the H3 C library, you'll need a C compiler (tested with `gcc` and `clang`), [CMake](https://cmake.org/), and [Make](https://www.gnu.org/software/make/). If you intend to contribute to H3, you must have [clang-format](https://clang.llvm.org/docs/ClangFormat.html) installed and we recommend installing [ccmake](https://cmake.org/cmake/help/v3.0/manual/ccmake.1.html) and [LCOV](http://ltp.sourceforge.net/coverage/lcov.php) to configure the `cmake` arguments to build and run the tests and generate the code coverage report. We also recommend using `gcc` for the code coverage as some versions of `clang` generate annotations that aren't compatible with `lcov`. [Doxygen](http://www.stack.nl/~dimitri/doxygen/) is needed to build the API documentation.
