+## Running tl in Docker
+
+This uses Docker to run tl to verify an existing file from the current working
+directory on the host machine.
+
+```
+docker run \
+	quay.io/transparencylog/tl:latest \
+	--mount type=bind,source=$PWD,target=/mnt \
+	/tl verify https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.1.tar.xz /mnt/linux-5.1.tar.xz
+```
+
+The return code will be forwarded from docker so you can test for non-zero exit
+for verification failure.
