I am having an issue building an image form the dockerfile. Namely, step 4/13 failed:

Step 4/13 : ADD neji-server.zip /opt/neji-server.zip
ADD failed: stat /var/lib/docker/tmp/docker-builder601862817/neji-server.zip: no such file or directory

I don't see /opt/neji-server.zip in the neji github directory, so I am not sure how to fix this issue.

Admittedly I do not know much about Docker/Dockerfiles so perhaps I am making a silly mistake. Any advice for setting up this docker would be appreciated!
