-Human Movement Sciences:
 "The choice of file format is a fundamental yet frequently overlooked consideration that directly impacts the findability, interoperability, and long-term reusability of shared human movement datasets... In this regard, the Hierarchical Data Format version 5 (HDF5) merits particular attention as a candidate for standardized data exchange in the human movement sciences."
-===== HDF5 Documentation =====
-A detailed description of our implementation of HDF5 can be found here, detailing the design decisions made.
 ===== 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
+==== 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.
