+    Glow is a terminal based markdown reader designed
+    from the ground up to bring out the beauty—and power—of the CLI.
+    Use it to discover markdown files,
+    read documentation directly on the command line and stash markdown files
+    to your own private collection, so you can read them anywhere.
+    Glow will find local markdown files in subdirectories or a local Git repository.
