+# @drexa/cli
+
+Admin CLI tool for managing Drexa resources.
+
+## Usage
+
+From the project root:
+
+```bash
+bun drexa <command> [subcommand] [options]
+```
+
+## Commands
+
+### `generate apikey`
+
+Generate a new API key for authentication.
+
+```bash
+bun drexa generate apikey
+```
+
+The command will interactively prompt you for (using Node.js readline):
+- **Prefix**: A short identifier for the key (e.g., 'proxy', 'admin'). Cannot contain dashes.
+- **Key byte length**: Length of the key in bytes (default: 32)
+- **Description**: A description of what this key is for
+- **Expiration date**: Optional expiration date in YYYY-MM-DD format
+
+The command will output:
+- **Unhashed key**: Save this securely - it won't be shown again
+- **Hashed key**: Store this in your database
+- **Description**: The description you provided
+- **Expiration date**: When the key expires (if set)
+
+## Development
+
+Run the CLI directly:
+
+```bash
+bun run apps/cli/index.ts <command>
+```
+
