+This app provides a way of exploring samples present in the MajorTOM-Core dataset.
+It contains nearly every piece of Earth capture by ESA Sentinel-2 satellite.
+
+### Instructions
+To find a sample, navigate on the map to a place of interest. Click `Find Sample` to find a dataset sample that contains the central pixel of your current view.
