-# tesseras-paste
+# Tesseras-Paste
+
+A decentralized pastebin built on [tesseras-dht](https://crates.io/crates/tesseras-dht). Pastes are encrypted client-side, distributed across the DHT, and served over HTTP.
+
+## Features
+
+- End-to-end encrypted pastes (XChaCha20-Poly1305)
+- Decentralized storage via Kademlia DHT
+- NAT traversal (hole-punching and proxy relay)
+- HTTP serving with content-key URLs
+- TTL-based expiry and pinning
+- Public (unencrypted) paste mode
+- OpenBSD `pledge(2)` sandboxing
+
+## Binaries
+
+**tpd** — daemon that runs a DHT node, stores pastes, and serves HTTP.
+
+```
+usage: tpd [-p port] [-d dir] [-s sock] [-w http_port] [-g] [-n] [-b host:port]
+
+  -p port       UDP port (0 = random)
+  -d dir        data directory
+  -s sock       Unix socket path
+  -w port       HTTP server port
+  -g            global NAT (public server)
+  -n            no auto-bootstrap (skip DNS SRV)
+  -b host:port  bootstrap peer (repeatable)
+```
+
+**tp** — CLI client that talks to the daemon over a Unix socket.
+
+```
+usage: tp [-s sock] <command> [args]
+
+  put [-t ttl] [-p]  read stdin, store paste (-p = public, no encryption)
+  get <key>          retrieve paste to stdout
+  del <key>          delete paste
+  pin <key>          pin (never expires)
+  unpin <key>        unpin
+  status             show daemon status
+```
+
+## Quick start
+
+```sh
+# Start the daemon
+tpd -p 4433 -w 9999 -d /var/tesseras-paste
+
+# Store a paste
+echo "hello" | tp put
+# => Ey2rNiNukhNpqUouaSnnZwTtCgeCgMx2FrCuMr3whBxx
+
+# Retrieve it
+tp get Ey2rNiNukhNpqUouaSnnZwTtCgeCgMx2FrCuMr3whBxx
+```
