+## tftp server
+
+a TFTP server (read/write) can be started using `--tftp 3969`  (you probably want [ftp](#ftp-server) instead unless you are *actually* communicating with hardware from the 80s (in which case we should definitely hang some time))
+
+* based on [partftpy](https://github.com/9001/partftpy)
+* needs a dedicated port (cannot share with the HTTP/HTTPS API)
+  * run as root to use the spec-recommended port `69` (nice)
+* no accounts; read from world-readable folders, write to world-writable, overwrite in world-deletable
+* [RFC 7440](https://datatracker.ietf.org/doc/html/rfc7440) is **not** supported (will be extremely slow over WAN)
+
+some recommended TFTP clients:
+* windows: `tftp.exe` (you probably already have it)
+* linux: `tftp-hpa`, `atftp`
+  * `tftp 127.0.0.1 3969 -v -m binary -c put initrd.bin`
+* `curl` (read-only)
+
+
 ## smb server
 
 unsafe, slow, not recommended for wan,  enable with `--smb` for read-only or `--smbw` for read-write
