 # GPKernels
 
-This work is in progress.
+### What is this?
+
+This is the documentation of a project to investigate the influence of the selection of
+kernels for [Gaussian processes](https://en.wikipedia.org/wiki/Gaussian_process) on the
+process of modeling light curves of different objects from the
+[Kepler Archive](https://archive.stsci.edu/kepler/data_search/search.php). For a look under
+the hood, visit the [project repository](https://github.com/paveloom-c/GPKernels).
+
+### What objects?
+
+These are the [F-type stars](https://en.wikipedia.org/wiki/F-type_main-sequence_star)
+mentioned in the paper
+[Mathur et al. (2014)](https://www.mendeley.com/catalogue/6be7d4d7-360f-3acb-9fc5-941020e088da/).
+They have published rotation periods, which are interesting to use when testing models. See
+more about object identifiers on the [`IDs`](@ref IDs) page.
+
+### Models, huh? What do they look like?
+
+Essentially it's a combination of a periodic kernel, some kernel adding attenuation,
+and white noise. That is, these are models of a quasi-periodic process. See the
+[`IDs`](@ref IDs) page for a complete list of models used.
+
+### What do I do next from here?
+
+Well, there's a section on the sidebar with all the notebooks, maybe that's worth checking
+out.
