# Usage

Running the most important Hello World on Lilypad!

Before you run a Lilypad job, make sure you have [Lilypad CLI installed](/lilypad/quickstart/cli/installation.md) and have set [a `WEB3_PRIVATE_KEY` env variable](/lilypad/quickstart/cli/installation.md#set-web3_private_key) in your environment.

{% hint style="info" %}
Your `WEB3_PRIVATE_KEY` can be retrieved from the MetaMask account details menu.  For more info, check out the [official guide from MetaMask](https://support.metamask.io/managing-my-wallet/secret-recovery-phrase-and-private-keys/how-to-export-an-accounts-private-key/) on how to get a your private key. **Be sure to keep your private key safe** and never share it or store it in unsecured places to prevent unauthorized access to your funds.
{% endhint %}

## Run Cowsay

`cowsay` is a classic CLI tool that prints messages in a speech bubble from an ASCII cow. You can run it as a job on the Lilypad network.

{% hint style="info" %}
By default, Lilypad CLI saves results to a temporary directory. To specify a custom directory for your job results, set the `DATA_DIR` environment variable before running your command: `export DATA_DIR=~/<DIRECTORY>`
{% endhint %}

Run the command:

```bash
lilypad run cowsay:v0.0.4 -i Message="moo"
```

Wait for the compute to take place and for the results to be published:

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.lilypad.tech/lilypad/quickstart/cli/usage.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
