+### Server Preparation 
+
+<br>
+Prepare server node in one terminal (#1)
+
+```
+export IPFS_PATH="~/.ipfs-p2p-server"
+ipfs init
+```
+
+<br>
+Enable Libp2pStreamMounting and start the daemon
+
+```
+ipfs config Experimental.Libp2pStreamMounting --bool true
+ipfs daemon &
+```
+
+<br>
+Start listening to forward the received connections to the target address
+
+```
+ipfs p2p listen /x/101-IPFS-Workshop/1.0 /ip4/127.0.0.1/tcp/22365
+```
+
+<br>
+Get server's ID
+
+```
+ipfs config Identity.PeerID
+```
+
+<br>
+
+### Client Preparation 
+
+<br>
+Prepare client node in another terminal (#2)
+
+```
+export IPFS_PATH="~/.ipfs-p2p-client"
+ipfs init
+```
+
+<br>
+Change the ports of the Addresses, enable Libp2pStreamMounting and start the daemon
+
+```
+ipfs config Addresses
+ipfs config edit
+ipfs config Experimental.Libp2pStreamMounting --bool true
+ipfs daemon &
+```
+
+<br>
+Forward specified client connection to server
+
+```
+ipfs p2p forward /x/101-IPFS-Workshop/1.0 /ip4/127.0.0.1/tcp/22366 /ipfs/<server Identity.PeerID>
+```
+
+
+<br>
+
+### Simple Test  
+
+<br>
+Start listening to the server's target address in one terminal
+
+```
+nc -l 127.0.0.1 22365
+```
+
+<br>
+Start streaming to the forwarded client connection in the other terminal
+
+```
+while true
+do
+    sleep 1
+    printf "%s\n" "$(date)"
+done | nc -v 127.0.0.1 22366
+```
+
+<br>
+
+### Media Test  
+
+<br>
+Prepare a named pipe for a little streaming 
+
+```
+mkfifo -m a+rw /tmp/pipe
+```
+
+<br>
+Start the media program in yet another terminal (#3)
+
+```
+/Applications/VLC.app/Contents/MacOS/VLC /tmp/pipe
+```
+
+<br>
+Start listening to forward to the pipe in another terminal
+
+```
+nc -l 127.0.0.1 22365 > /tmp/pipe
+```
+
+<br>
+Start streaming yet in another terminal
+
+```
+cat ~/Desktop/testmovie.mp4 | nc -v 127.0.0.1 22366
+```
+
+Bug: Last two steps has to be done again.
+
+
+<br>
+### Clean up 
+
+<br>
+Closing the terminals #1 and #2 will stop the ipfs daemons.
+<br>
+
+<br>
+Remove named pipe and config directories
+
+```
+rm /tmp/pipe
+rm -rf ~/.ipfs-p2p-client ~/.ipfs-p2p-server
+```
