# Editing the portal

You can click inside the circles that are on the portal. A menu will pop and you can change the frame block, the inside block, the lighter and change a few other options.

## Frame block

When you click at the top left of the portal, this menu will pop

You can choose the face of the block to be accepted (for example you can set a portal to only ignite if the (for example) acacia log is placed along the Y axis)

Then you can set the minimum portal size (minimum width **x** minimum height) and the maximum size (maximum width **x** maximum height)

After you are done with these optional changes you can choose a block from the list below or you can enter the block you want to use manually (If the editor does not have the block you entered, then it will use another image)

## Inside block & Lighter material

When you click inside the circle at the portal's inside or at the lighter you will get a small box listing blocks & items that can be used. Similar to the frame block, you can input a block manually

## 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://astaspastagam.gitbook.io/first-steps/configuring-dimensions/portal-creator/editing-the-portal.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.
