+# sshell
+
+A personal SSH and shell connection manager with a terminal user interface (TUI), built in Rust.
+
+## Features
+
+- **Connection management** — SSH and local shell profiles with tagging, usage tracking, and smart sorting
+- **Credential storage** — Passwords and SSH private keys stored securely in config
+- **Import from `~/.ssh/config`** — One command to import all existing hosts
+- **Local shell scan** — Auto-detects available shells from `/etc/shells`
+- **Quick select** — Press `Ctrl+Q` then a number key (1–9) to connect instantly
+- **Encrypted cloud sync** — Push/pull config via GitHub Gist, WebDAV, or S3 with AES-256-GCM encryption
+- **CLI subcommands** — Connect, import, sync, and diagnostics without launching the TUI
+
+## Installation
+
+```bash
+cargo build --release
+```
+
+The binary will be at `target/release/sshell`.
+
+### Runtime requirements
+
+- `ssh` — for SSH connections
+- `sshpass` — for password-based SSH authentication
+
+## Usage
+
+```bash
+# Launch the TUI
+sshell
+
+# Connect directly by name
+sshell connect myserver
+
+# Import hosts from ~/.ssh/config
+sshell import
+
+# Sync
+sshell sync push
+sshell sync pull --strategy merge
+
+# Diagnostics
+sshell doctor
+sshell doctor myserver
+
+# Print config file path
+sshell config-path
+```
+
+## Configuration
+
+Config is stored at `~/.config/sshell/config.toml` (auto-created on first run).
+
+```toml
+version = 2
+
+[settings]
+backend = "gist"
+gist_id = "..."
+sync_password = "..."
+
+[connections.myserver]
+type = "ssh"
+host = "example.com"
+port = 22
+user = "admin"
+auth_ref = "myserver-password"
+tags = ["production"]
+
+[credentials.myserver-password]
+type = "password"
+value = "secret123"
+```
