+## Troubleshooting
+
+### Terminal type / colors over SSH
+
+Clients such as [Ghostty](https://ghostty.org/) set `TERM` to values like `xterm-ghostty`. SSH forwards that to the server, but the server usually has no matching terminfo entry. Symptoms include:
+
+- `'xterm-ghostty': unknown terminal type` when running `./install.sh` (the interactive menu calls `clear`)
+- Broken or missing colors in `vim`, `htop`, `tmux`, and other TUI programs
+
+`install.sh` detects an unknown `TERM` at startup and falls back to the first available of `xterm-256color`, `xterm`, `screen`, or `dumb`. You can also use the non-interactive installer: `./install.sh --all`.
+
+For **all future SSH sessions** to any server, force a portable `TERM` on the client before connecting. Add a wrapper on your **local** machine (not the server). The function body is the same in bash and zsh; what differs is where you put it and how you check that it took effect.
+
+**Bash** (`~/.bashrc`) — append at the end of the file:
+
+```bash
+unalias ssh 2>/dev/null
+ssh() {
+  TERM=xterm-256color command ssh "$@"
+}
+```
+
+**Zsh** (`~/.zshrc`) — append at the end, *after* Oh-My-Zsh and other plugins so nothing loads later and overrides it:
+
+```zsh
+unalias ssh 2>/dev/null
+ssh() {
+  TERM=xterm-256color command ssh "$@"
+}
+```
+
+Zsh also allows `function ssh { ... }` with the same body; `ssh() { ... }` is equivalent. In both shells, `command ssh` calls the real binary and avoids recursion.
+
+| | Bash | Zsh |
+|---|------|-----|
+| Config file | `~/.bashrc` | `~/.zshrc` |
+| Placement | End of file | End of file, after OMZ/plugins |
+| Clear alias first | `unalias ssh` (if present) | Same — plugins sometimes define `ssh` aliases |
+| Argument forwarding | `"$@"` | `"$@"` — not `"@"` |
+| Reload | `exec bash` or new terminal | `exec zsh` or new terminal |
+| Check wrapper is active | `type ssh` | `whence -v ssh` (`type` can be ambiguous in zsh) |
+
+Verify:
+
+```sh
+# bash
+type ssh
+ssh myhost 'echo $TERM'
+
+# zsh
+whence -v ssh
+ssh myhost 'echo $TERM'
+```
+
+Both should report a shell function and print `xterm-256color` on the remote host.
+
+One-off:
+
+```sh
+TERM=xterm-256color ./install.sh
+```
+
+Optional: in `~/.ssh/config`, `SetEnv TERM=xterm-256color` under `Host *` only works when the remote `sshd` accepts `TERM` via `AcceptEnv` — many servers do not, so the shell wrapper above is more reliable.
