+# Simplify installation for Scratch 456.0.1 on Linux #
+
+These scripts simplify the deployment and distribution of Scratch on
+GNU/Linux.
+
+## Installation ##
+
+Run the `install.sh` script as root to install Scratch on the local machine on
+`/opt/scratch`:
+
+    sudo bash install.sh
+
+## Adobe AIR and redistribution ##
+
+You should not distribute Adobe AIR based on Adobe AIR License, so we have
+devised a script to install it on GNU/Linux systems accepting the License and
+using Adobe AIR SDK for simplified management.
+
+Adobe AIR installation is managed at first launch of Scratch (via the
+`scratch-wrapper.sh` script) or it can be done launching the
+`air-installer.sh` script by hand with root:
+
+    sudo bash air-installer.sh
