# Welcome

Earth LinC is one space — your **Realm** — and what you reach from it.

You begin in the Realm. The **Airwaves** carry every public station; your **asterism** holds the stars cast to you. From **Stations** you compose a page, **crown** it onto the chain, and **cast** stars from it to the people you choose — each one landing in someone else's Realm, where the same map applies.

That's the whole product. A page you make, made permanent, and sent to someone by name.

New here? Start with [What is Earth LinC](/protocol/start-here/what-is-earth-linc.md). Then find your way from the center out: [The Realm](/protocol/the-realm/the-realm.md) → [Stations](/protocol/stations/stations-and-your-collection.md) → [Cast](/protocol/stations/cast.md).

Want to do something real for this earth as you go? That's [C//](/protocol/c/c-slash.md). Wondering where money goes? [Money, plainly](/protocol/money-plainly/money-plainly.md). Want your own keys? [Claim & custody](/protocol/claim-and-custody/claim-and-custody.md).

Building on it, or here for the on-chain detail? See the [Protocol](/protocol/protocol/protocol-specification.md) section.

*Earth LinC · the open sky. LinC for good.*

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://earthlinc.gitbook.io/protocol/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
