-### Using Vagrant
-
-It's possible that your system doesn't handle the network correctly for the interop tester to work. In this case, a Vagrant box is available:
-
-``` sh
-# Spin up the vagrant box
-vagrant up
-
-# Then, connect to it and start testing
-vagrant ssh
-(cd ../ && docker build -f Dockerfile  -t stammw/quinn-interop:latest .) \
-    && python3 run.py -d -s quic-go -c quinn
-```

-When you need to start hacking a bit, this command might be handy:
-
-``` sh
-vagrant rsync-auto
