+# Description
+
+### What is this?
+
+This is a repository of a project to investigate the influence of the selection of kernels
+for Gaussian processes on the process of modeling light curves of different objects from
+the Kepler Archive. For more information on the research, see the
+[online documentation](https://paveloom-c.github.io/GPKernels).
+
+### Wait, why isn't this branch called `master`/`main`?
+
+This repository consists of four main branches:
+* [`notebooks`](https://github.com/paveloom-c/GPKernels/): contains Jupyter notebooks and
+Julia scripts to convert these notebooks to Markdown files;
+* [`docker`](https://github.com/paveloom-c/GPKernels/tree/docker): provides a Docker image
+that contains the development environment for this project;
+* [`okteto`](https://github.com/paveloom-c/GPKernels/tree/okteto): provides a configuration
+YAML file for Kubernetes;
+* [`gh-pages`](https://github.com/paveloom-c/GPKernels/tree/gh-pages): contains the
+automatically converted documentation files.
+
+### What do these releases mean?
+
+Releases involve changes on the [`notebooks`](https://github.com/paveloom-c/GPKernels/)
+branch, that is, the research process.
