+UCSC Single Cell Browser
+========================
+
+Funded by the California Institute of Regenerative Medicine and the Chan-Zuckerberg
+Initiative https://www.chanzuckerberg.com/.
+
+The UCSC Cell Browser is a viewer for single cell data. You can click on and hover
+over cells to get meta information, search for genes to color on and click clusters
+to show cluster-specific marker genes, which in turn are clickable again.
+
+For a demo of the browser, see http://cells.ucsc.edu
+
+Usage
+-----
+
+After choosing the inputs and executing the tool, once the history item becomes
+green, press the View data (eye icon) button, which will open the generated UCSC Cell Browser
+interactive site. Press the white on blue "Open Dataset" button.
+
+Troubleshooting
+---------------
+
+Depending on the window size when pressing the "View data" button, you might see a black canvas and a diminished panel to the upper left
+with the text "Choose cell...". If that is the case, close that panel (click on the cross)
+and then choose File -> Open Dataset... and then press the Open Dataset white button.
