+# Exercises signature
+
+This plugin allows the teacher to check a box in any exercise configuration to request a signature from the user at the end of the exercise attempt.
+
+A modal window, a bit like a mini-whiteboard, will then appear to students asking them to sign. The signature can be done through the mouse (unpractical), through a touch device (ideal with tablets) or through a touch-sensitive laptop screen.
+
+Teachers will see the signature when they review the attempt details.
+
+## Installation
+
+This plugin creates extra fields for exercises automatically.
+
+Signatures are saved as a drawing in the database.
+
+Uninstalling this plugin will remove the extra fields, so all signatures will disappear (instantly) if you uninstall this. Consider using the "disable" option inside the plugin configuration instead.
