+# @toon-format/cli
+
+Command-line tool for converting between JSON and TOON formats.
+
+[TOON (Token-Oriented Object Notation)](https://toonformat.dev) is a compact, human-readable serialization format designed for passing structured data to Large Language Models with significantly reduced token usage.
+
+## Installation
+
+```bash
+# npm
+npm install -g @toon-format/cli
+
+# pnpm
+pnpm add -g @toon-format/cli
+
+# yarn
+yarn global add @toon-format/cli
+```
+
+Or use directly with `npx`:
+
+```bash
+npx @toon-format/cli [options] [input]
+```
+
+## Usage
+
+```bash
+toon [options] [input]
+```
+
+**Standard input:** Omit the input argument or use `-` to read from stdin. This enables piping data directly from other commands.
+
+**Auto-detection:** The CLI automatically detects the operation based on file extension (`.json` → encode, `.toon` → decode). When reading from stdin, use `--encode` or `--decode` flags to specify the operation (defaults to encode).
+
+### Basic Examples
+
+```bash
+# Encode JSON to TOON (auto-detected)
+toon input.json -o output.toon
+
+# Decode TOON to JSON (auto-detected)
+toon data.toon -o output.json
+
+# Output to stdout
+toon input.json
+
+# Pipe from stdin
+cat data.json | toon
+echo '{"name": "Ada"}' | toon
+
+# Decode from stdin
+cat data.toon | toon --decode
+```
+
+## Options
+
+| Option | Description |
+| ------ | ----------- |
+| `-o, --output <file>` | Output file path (prints to stdout if omitted) |
+| `-e, --encode` | Force encode mode (overrides auto-detection) |
+| `-d, --decode` | Force decode mode (overrides auto-detection) |
+| `--delimiter <char>` | Array delimiter: `,` (comma), `\t` (tab), `\|` (pipe) |
+| `--indent <number>` | Indentation size (default: `2`) |
+| `--length-marker` | Add `#` prefix to array lengths (e.g., `items[#3]`) |
+| `--stats` | Show token count estimates and savings (encode only) |
+| `--no-strict` | Disable strict validation when decoding |
+
+## Advanced Examples
+
+### Token Statistics
+
+Show token savings when encoding:
+
+```bash
+toon data.json --stats -o output.toon
+```
+
+Example output:
+```
+✓ Encoded to TOON
+  Input:  15,145 tokens (JSON)
+  Output:  8,745 tokens (TOON)
+  Saved:   6,400 tokens (42.3% reduction)
+```
+
+### Alternative Delimiters
+
+#### Tab-separated (often more token-efficient)
+
+```bash
+toon data.json --delimiter "\t" -o output.toon
+```
+
+#### Pipe-separated with length markers
+
+```bash
+toon data.json --delimiter "|" --length-marker -o output.toon
+```
+
+### Lenient Decoding
+
+Skip validation for faster processing:
+
+```bash
+toon data.toon --no-strict -o output.json
+```
+
+### Stdin Workflows
+
+```bash
+# Convert API response to TOON
+curl https://api.example.com/data | toon --stats
+
+# Process large dataset
+cat large-dataset.json | toon --delimiter "\t" > output.toon
+
+# Chain with other tools
+jq '.results' data.json | toon > filtered.toon
+```
+
+## Why Use the CLI?
+
+- **Quick conversions** between formats without writing code
+- **Token analysis** to see potential savings before sending to LLMs
+- **Pipeline integration** with existing JSON-based workflows
+- **Flexible formatting** with delimiter and indentation options
