+      exa is a modern replacement for ls. It uses colours for information by
+      default, helping you distinguish between many types of files, such as
+      whether you are the owner, or in the owning group. It also has extra
+      features not present in the original ls, such as viewing the Git status
+      for a directory, or recursing into directories with a tree view. exa is
+      written in Rust, so it’s small, fast, and portable.
