+Each supported operating system has two dockerfiles, one for building and one for testing. This example is for building and testing Ubuntu 18.04 LTS

     sudo docker run -v /tmp:/build --rm  kasmvncbuilder:18.04
+    cp /tmp/build/kasmvnc.ubuntu_18.04.tar.gz builder/build/
+```
 
-# tar will be on /tmp of host
+### Build test desktop container
-    cp /tmp/kasmvnc*.tar.gz builder/
+```sh
-
-# build test desktop container with new binary installed
     cd builder
-    sudo docker build -t kasmvnctester:18.04 -f dockerfile.test .
