+
+## Key Components
+
+### Models (`pkg/models/`)
+
+The core data structures:
+
+- **Host** — SSH host with address, credentials, group, tags
+- **Key** — SSH key metadata
+- **Snippet** — Reusable connection snippets
+
+### Configuration (`pkg/config/`)
+
+Manages application configuration, data directory path, and initialization.
+
+### Storage (`pkg/storage/`)
+
+Handles persistent storage:
+- File-based JSON storage per data type
+- Export/import with replace and merge strategies
+- File permission enforcement (0600)
+
+### CLI Layer (`cmd/hostkeeper/`)
+
+Each command follows a consistent pattern:
+1. Parse flags
+2. Load config and storage
+3. Execute business logic
+4. Format output
+
+### TUI (`pkg/tui/`)
+
+Bubble Tea model with:
+- Screen-based navigation (extensible for future screens)
+- Host list view with styled output
+- Keyboard-driven interaction
+
+## Data Flow
+
+### Adding a Host
+
+```
+User → hostkeeper add (flags) → parse args → Host model → storage.SaveHost() → JSON file
+```
+
+### Connecting to a Host
+
+```
+User → hostkeeper connect <name> → findHost() by ID → resolve key → exec native SSH or Go SSH
+```
+
+### Export/Import
+
+```
+Export: storage → marshal JSON → write file
+Import: read file → unmarshal → strategy (merge/replace) → save all
+```
+
+## Security
+
+- Credential files stored with `0600` permissions
+- SSH key content stored within host credentials
+- Direct mode uses Go SSH client (no shell, command execution only)
+- Native SSH mode delegates all terminal handling to system SSH
+
+## Future Architecture
+
+- SQLite database for improved query capabilities
+- Encrypted credential storage (age/gpg)
+- Configuration encryption
+- Plugin system for custom authentication methods

+# Installation Guide
+
+## Prerequisites
+
+- **Go 1.21+** — for building from source
+- **Git** — for cloning the repository
+- **Make** — optional, for build automation
+
+## Installation Methods
+
+### Method 1: Build from Source
+
+```bash
+git clone https://git.tukangketik.id/swanadiva/HostKeeper.git
+cd hostkeeper
+make build
+sudo cp bin/hostkeeper /usr/local/bin/
+```
+
+### Method 2: Go Install
+
+```bash
+go install git.tukangketik.id/swanadiva/hostkeeper/cmd/hostkeeper@latest
+```
+
+This installs to `$GOPATH/bin` or `$HOME/go/bin`.
+
+### Method 3: Cross-Platform Build
+
+```bash
+./build.sh
+```
+
+Binaries will be in the `build/` directory with SHA256 checksums.
+
+## Platform-Specific Instructions
+
+### macOS
+
+```bash
+# Install Go via Homebrew
+brew install go
+
+# Build and install
+git clone https://git.tukangketik.id/swanadiva/HostKeeper.git
+cd hostkeeper
+make build
+cp bin/hostkeeper /usr/local/bin/
+```
+
+### Linux (Ubuntu/Debian)
+
+```bash
+# Install Go
+sudo apt update
+sudo apt install golang git make
+
+# Build and install
+git clone https://git.tukangketik.id/swanadiva/HostKeeper.git
+cd hostkeeper
+make build
+sudo cp bin/hostkeeper /usr/local/bin/
+```
+
+### Windows
+
+```powershell
+# Install Go from https://golang.org/dl/
+# Clone repository
+git clone https://git.tukangketik.id/swanadiva/HostKeeper.git
+cd hostkeeper
+
+# Build
+go build -o hostkeeper.exe ./cmd/hostkeeper
+```
+
+### Termux (Android)
+
+```bash
+pkg install golang git make
+git clone https://git.tukangketik.id/swanadiva/HostKeeper.git
+cd hostkeeper
+make build
+cp bin/hostkeeper $PREFIX/bin/
+```
+
+## Verification
+
+```bash
+hostkeeper version
+```
+
+Expected output:
+```
+hostkeeper dev (built: ...)
+```
+
+## Troubleshooting
+
+### Command Not Found
+
+Ensure the binary is in your PATH:
+```bash
+export PATH=$PATH:/usr/local/bin
+```
+
+### Build Failures
+
+```bash
+make clean
+make deps
+make build

+# Usage Guide
+
+## Host Management
+
+### Add a Host
+
+Interactive mode:
+```bash
+hostkeeper add
+```
+
+With flags:
+```bash
+hostkeeper add myserver --host 192.168.1.10 --user admin --password mypass
+hostkeeper add myserver --host 10.0.0.1 --port 2222 --user root --key ~/.ssh/id_rsa
+hostkeeper add webserver --host example.com --user deploy --password secret --group production --tags web,frontend
+```
+
+Flags:
+- `--host` — hostname or IP address
+- `--port` — SSH port (default: 22)
+- `--user` — SSH username
+- `--password` — SSH password
+- `--key` — path to SSH private key
+- `--auth-type` — authentication type (password, key, both)
+- `--group` — host group for categorization
+- `--tags` — comma-separated tags
+- `--notes` — notes about the host
+
+### List Hosts
+
+```bash
+hostkeeper list
+hostkeeper ls  # alias
+```
+
+Filter by group or tag:
+```bash
+hostkeeper list --group production
+hostkeeper list --tag web
+```
+
+Output formats:
+```bash
+hostkeeper list --format table  # default
+hostkeeper list --format json
+```
+
+Sort options:
+```bash
+hostkeeper list --sort name      # default
+hostkeeper list --sort hostname
+hostkeeper list --sort group
+```
+
+### Connect to a Host
+
+Connect using system SSH (default, full interactive terminal):
+```bash
+hostkeeper connect myserver
+```
+
+Connect with Go SSH client (direct mode, no interactive shell):
+```bash
+hostkeeper connect myserver --direct
+```
+
+Custom timeout:
+```bash
+hostkeeper connect myserver --timeout 60
+```
+
+### Edit a Host
+
+Interactive mode:
+```bash
+hostkeeper edit myserver
+```
+
+With flags (only update what you specify):
+```bash
+hostkeeper edit myserver --host 10.0.0.1 --port 2222
+hostkeeper edit myserver --user root --name myserver-renamed
+hostkeeper edit myserver --group staging --tags backend
+```
+
+### Delete a Host
+
+With confirmation prompt:
+```bash
+hostkeeper delete myserver
+hostkeeper rm myserver  # alias
+```
+
+Skip confirmation:
+```bash
+hostkeeper delete myserver --force
+```
+
+## Data Management
+
+### Export
+
+Export all hosts, keys, and snippets to a JSON file:
+```bash
+hostkeeper export backup
+hostkeeper export backup.json
+```
+
+### Import
+
+Import from a previously exported JSON file:
+```bash
+hostkeeper import backup.json  # merge (default)
+hostkeeper import backup.json --strategy replace
+hostkeeper import backup.json --dry-run  # preview only
+```
+
+Merge strategies:
+- `merge` — keep existing data, add new items (default)
+- `replace` — replace all existing data with imported data
+
+## TUI Interface
+
+Launch the interactive terminal UI:
+```bash
+hostkeeper tui
+```
+
+Navigation:
+- `↑`/`k` — move up
+- `↓`/`j` — move down
+- `Enter` — select host
+- `q` — quit
+
+## Shell Completion
+
+Generate shell completion scripts:
+```bash
+hostkeeper completion bash > /etc/bash_completion.d/hostkeeper
+hostkeeper completion zsh > /usr/local/share/zsh/site-functions/_hostkeeper
+hostkeeper completion fish > ~/.config/fish/completions/hostkeeper.fish
+hostkeeper completion powershell > hostkeeper.ps1
+```
+
+## Global Flags
+
+- `--config` — path to custom config file
+- `-v`/`--verbose` — verbose output (-v for info, -vv for debug)
+- `--debug` — enable debug mode
+- `--help` — display help
