+                HyFetch is a command-line system information tool fork of neofetch.
+                HyFetch displays information about your system next to your OS logo
+                in ASCII representation. The ASCII representation is then colored in
+                the pattern of the pride flag of your choice. The main purpose of
+                HyFetch is to be used in screenshots to show other users what
+                operating system or distribution you are running, what theme or
+                icon set you are using, etc.
