+# Dataclasses for pyiron
+The `pyiron_dataclasses` module provides a series of [dataclasses](https://docs.python.org/3/library/dataclasses.html) 
+for the `pyiron` workflow framework. It can load HDF5 files created by `pyiron_atomistics` and read the content stored 
+in those files, without depending on `pyiron_atomistics`. Furthermore, it is not fixed to a single version of 
+`pyiron_atomistics` but rather matches multiple versions of `pyiron_atomistics` to the same API version of 
+`pyiron_dataclasses`. 
+
+## Usage 
+Using the `get_dataclass()` function of the built-in converter:
+```python
+from h5io_browser import read_dict_from_hdf
+from pyiron_dataclasses.v1.converter import get_dataclass
+
+job_classes = get_dataclass(
+    job_dict=read_dict_from_hdf(
+        file_name=job.project_hdf5.file_name,
+        h5_path="/",
+        recursive=True,
+        slash='ignore',
+    )[job.job_name]
+)
+job_classes
+```
+
+## Supported Versions 
+### Version 1 - `v1`
+Supported versions of `pyiron_atomistics`:
+* `0.6.13`
+* `0.6.12`
