# Verifying the installation on Linux

1. In the console, type `cd $DITA_HOME`
2. Type `ant -f build.demo.xml all` and press Enter to begin to process the DITA files in the demo, doc, docbook, and samples directories. This procedure also verifies the Toolkit installation. The testing process completes in 3-10 minutes depending on the speed of your machine. When testing completes, the confirmation message `BUILD SUCCESSFUL` displays.

Be sure the directories and files in your DITA-OT1.5.3 are as described in Directories and files in the DITA-OT1.5.3 root directory.
