+# Arbor
+
+**Arbor** is a command-line application written in Rust, designed to provide quick, trie-based autocomplete suggestions. Arbor lets users enter words interactively and suggests completions based on the input prefix.
+
+## Interactive Mode
+
+In interactive mode, Arbor will prompt you to enter words or prefixes. Based on the entered text, it will provide autocomplete suggestions.
+
+1. **Adding Words**: Type a word and press Enter to add it to the trie.
+2. **Autocomplete Suggestions**: Type a prefix and press Enter to see a list of words that match the prefix.
+
+### Example:

+
+## Features
+
+- **Interactive Autocomplete** - Provides word suggestions based on prefixes entered by the user.
+- **Efficient and Lightweight** - Built with Rust for high performance and low memory usage.
+- **Easy Installation** - Can be installed directly via Cargo.
+
+## Installation
+
+You can install Arbor using Cargo:
+
+```bash
+cargo install arbor
+```
+
+## Usage
+
+After installation, simply run `arbor` in your terminal:

+```bash
+arbor
+```
+
+### Command-Line Options
+
+- **`-l`, `--language <LANGUAGE>`**: Specifies the language for suggestions (e.g., `en-US`).
+- **`-t`, `--thread-count <THREAD_COUNT>`**: Sets the number of threads for processing (e.g., `4`).
+- **`-m`, `--max-suggestion <MAX_SUGGESTION>`**: Limits the number of suggestions returned for a prefix (e.g., `5`).
+- **`-b`, `--backup`**: Enables backup mode. When this flag is set, you must also specify the `--output` option.
+- **`-o`, `--output <FILE>`**: Specifies the file path for saving backup suggestions (only applicable if `--backup` is enabled).
