+Bitcoin Utils CLI (bu) - Command line interface for python-bitcoin-utils
+
+This CLI tool provides educational utilities to interact with Bitcoin through
+the python-bitcoin-utils library. It's designed to help understand the 
+inner workings of Bitcoin through practical examples and utilities.
+
+Installation Instructions:
+------------------------
+
+1. Make the file executable:
+   $ chmod +x bitcoin_utils_cli.py
+
+2. Create a symlink named 'bu' in your PATH:
+   $ sudo ln -s /path/to/bitcoin_utils_cli.py /usr/local/bin/bu
+
+   Or using pip (if included in a package):
+   $ pip install python-bitcoin-utils[cli]
+
+Usage:
+------
+   $ bu --help
+   $ bu generate
+   $ bu validate 1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH --pubkey 0450863AD64A87AE8A2FE83C1AF1A8403CB53F53E486D8511DAD8A04887E5B23522CD470243453A299FA9E77237716103ABC11A1DF38855ED6F2EE187E9C582BA6
+   $ bu decode <transaction_hex>
+   $ bu script <script_hex>
+   $ bu block <block_file_path>
