+# qft
+QFT is a small command line application for Quick Peer-To-Peer UDP file transfer.
+
+## Usage:
+- Find a public QFT helper (for example tudbut.de:4277)
+- On the sender PC, enter `qft sender <helper> <shared-phrase> <filename>`.
+- On the receiver PC, enter `qft receiver <helper> <shared-phrase> <filename>`.
+- Both PCs should start transferring after a short while. If they don't, try again.
+
+## Tips 'n Tricks
+- You can add a number to the end of both of your commands (after the filename) to
+  boost transfer speeds (higher = faster), but a too large number might cause unreliability
+  due to local network conditions or VPNs.
+
+## Troubleshooting
+
+### It constantly says `CONNECTING`
+One of your ends didn't correctly connect to the helper. Stop the transfer on both ends
+and try again.
