 # Dosh
 
-Dosh is a fast encrypted remote terminal. It keeps the good parts of SSH and
-Mosh for day-to-day shell work: quick attach, roaming over UDP, reconnect after
-network changes, persistent server-side terminals, optional predictive typing,
-and TCP forwarding.
+Dosh is an encrypted remote terminal for fast reconnecting shells.
 
-Dosh uses SSH-compatible bootstrap for first setup and can use its native
-cached attach path after trust is established. The goal is simple: type
-`dosh my-server` and land in a usable terminal about as fast as the network can
-allow, then keep that terminal alive when Wi-Fi, sleep, or the client process
-gets messy.
+It runs a `dosh-server` on the remote machine and a `dosh` client locally. The
+first setup can use SSH. After that, Dosh can attach over encrypted UDP with
+cached credentials, keep terminal sessions alive, reconnect after network
+changes, and forward TCP ports.
 
-## Status
+## Support
 
-- Clients: macOS, Linux, and Windows.
-- Server: Unix-like hosts with PTY support.
-- Windows: client-only; install with PowerShell and connect to a Unix Dosh
-  server.
-- Security: encrypted transport, pinned Dosh host keys, replay-resistant attach
-  tickets, and SSH fallback for bootstrap/recovery.
-- Not included: X11 forwarding, SFTP/SCP replacement, or a Windows server.
+- Client: macOS, Linux, Windows
+- Server: Unix-like systems with PTYs
+- Windows: client only
+- UDP port: one configured server port, default `50000`
+
+Dosh does not replace SCP, SFTP, X11 forwarding, or a Windows server.

-## Use
-
-Set up a host from your SSH config:
+## Commands
 
 ```sh
-dosh setup my-server
+dosh setup HOST          # import SSH config and trust the Dosh host key
+dosh HOST                # connect
+dosh HOST COMMAND        # connect and run a command
+dosh update              # update Dosh
+dosh doctor HOST         # check config and connectivity
+dosh recover HOST        # clear cached attach state and re-check
 ```
 
-Connect:
+Examples:
 
 ```sh
-dosh my-server
+dosh palav
+dosh palav tm
+dosh forward palav -L 8080:127.0.0.1:80
+dosh forward palav -D 1080
+dosh forward palav -R 2222:127.0.0.1:22
 ```
 
-Run a command on connect:
-
-```sh
-dosh my-server tm
-```
-
-Check the install and network path:
-
-```sh
-dosh doctor my-server
-dosh selftest my-server
-```
-
-Repair local cached attach state without changing host trust:
-
-```sh
-dosh recover my-server
-```
-
-Update:
-
-```sh
-dosh update
-dosh update --check
-```
-
-## Forwarding
-
-Local forward:
-
-```sh
-dosh forward my-server -L 8080:127.0.0.1:80
-```
-
-Dynamic SOCKS forward:
-
-```sh
-dosh forward my-server -D 1080
-```
-
-Remote forward:
-
-```sh
-dosh forward my-server -R 2222:127.0.0.1:22
-```
-
-Agent forwarding is opt-in with `-A` and must also be allowed by the server.
+Agent forwarding is opt-in with `-A` and must be enabled on the server.
 
 ## Config
 
-Client config lives at:

 ~/.config/dosh/server.toml
 ```
 
-Useful client defaults:
+Common client settings:
 
 ```toml
 default_session = "new"
 auth_preference = "native,ssh"
 predict = true
-predict_mode = "experimental"
