## What is HDF5?
This repository contains a high-performance library's source code and a file format
specification that implements the HDF5® data model. The model has been adopted across
many industries, and this implementation has become a de facto data management standard
in science, engineering, and research communities worldwide.
The HDF Group is the developer, maintainer, and steward of HDF5 software. Find more
information about The HDF Group, the HDF5 Community, and other HDF5 software projects,
tools, and services at [The HDF Group's website](https://www.hdfgroup.org/).
## Quick Start
- **New to HDF5?** Start with the [INSTALL](release_docs/INSTALL) guide for compilation and installation instructions.
- **Ready to build?** See [INSTALL_CMake.txt](release_docs/INSTALL_CMake.txt) for CMake-based builds.
- **Running on HPC?** Check out [README_HPC.md](release_docs/README_HPC.md) for parallel HDF5 configuration.
