+## 0.0.1 - 2020-11-30
+
+First release to PyPI.
+
+This release comes with the first version of the `contributing` module, which makes it easier
+to create new primitives and to test those with the demo data included in this package.
+
+This release also includes the following User Guides:
+
+* [PRIMITIVES.md](https://github.com/signals-dev/SigPro/blob/master/PRIMITIVES.md): Information
+  about the primitive families, their expected input and output.
+* [USAGE.md](https://github.com/signals-dev/SigPro/blob/master/USAGE.md): Instructions about how
+  to usee the three main functionalities of `SigPro`.
+* [DEVELOPMENT.md](https://github.com/signals-dev/SigPro/blob/master/DEVELOPMENT.md): Step by step
+  guide about how to write a valid `SigPro` primitive and contribute it to either `SigPro` or
+  your own library.
+
+### Features
+
+* Demo data: Available demo data to test primitives.
+* First primitives: The following list of primitives were added:
+  * `sigpro.aggregations.amplitude.statistical.crest_factor`
+  * `sigpro.aggregations.amplitude.statistical.kurtosis`
+  * `sigpro.aggregations.amplitude.statistical.mean`

+  * `sigpro.transformations.frequency_time.stft.stft`
+  * `sigpro.transformations.frequency_time.stft.stft_real`
+* Contributing module.
+* Documentation on how to contribute new primitives and how to run those.
