+# Lens CLI
+
+CLI tool for Lens developers.
+
+**Please note, this is an experimental tool and it may undergo significant changes in the future.**
+
+## Usage
+
+Install the Lens CLI from npm.
+
+```bash
+npm install -g @lens-protocol/cli
+```
+
+See the available commands. The first level command decides the environment: `development` or `production`.
+You can use shorthand `dev` and `prod` instead.
+
+```bash
+lens development --help
+```
+
+or
+
+```bash
+lens production --help
+```
+
+## Local Setup
+
+First install dependencies. Run all commands from the monorepo root directory.
+
+```bash
+pnpm install
+```
+
+Start the development mode. It will watch for changes and rebuild the CLI.
+
+```bash
+pnpm --dir packages/cli dev
+```
+
+Then link the package globally.
+
+```bash
+pnpm --dir packages/cli link --global
+```
+
+Now you can run the CLI from anywhere.
+
+```bash
+lens --help
+```
+
+Delete the global link when you're done.
+
+```bash
+pnpm remove --global @lens-protocol/cli
+```
