+# Changelog for Skyfield Data
+
+## 0.0.1 (2019-07-29)
+
+Initial release
+
+* This project includes minimal data files required by the [Python Skyfield library](https://rhodesmill.org/skyfield/): `de421.bsp`, `deltat.data`, `deltat.preds` and `Leap_Second.dat`,
+* It provides a small Python script to download the files from their respective source,
+* This script eventually checks if some of the files are expired and skips them (by default),
+* Usage documentation is included in the `README.md` file.
+* This project code is released under the terms of the MIT License.
