 ===== Working With HDF5 =====
-Conducting processing using HDF5 has been made easy but the plentiful libraries provided for many programming languages from Python to C++, the file can also easily be read using the HDF groups on application HDFView. We have created a document to support work with the HDF5 files produced by Visual3D link
+==== HAS-Motion Documentation ====
+Here is a doc detailing our implementation of the HDF5 format. The latest version is **v0.0.1** (as of 8/20/2026).
+=== What's New ===
+  * Version number is now tracked at the root group level, making version information easier to access and manage.
+  * Signal data is now stored using a more appropriate data type, resulting in smaller file sizes and more efficient storage.

+==== HDFView ====
+The HDF Group maintains a free to use .h5 viewer named [[https://www.hdfgroup.org/download-hdfview/|HDFView]].
+==== Libraries ====
+Several libraries exist allowing users to interface with .h5 files from an array of languages [[https://docs.h5py.org/en/stable/|h5py]] for Python being the most popular.
