+## What is this?
+
+This package detects whether text is written left-to-right or right-to-left.
+
+## When should I use this?
+
+This is a simple and fast algorithm.
+It looks at the first strong left-to-right or right-to-left character (for
+example, the letter `a` is LTR, the letter `ى` is RTL).
+That’s often enough but might be too naïve as it doesn’t take percentages or so
+into account.
