# Detailed Guides
Take Bitmap - THE·BITMAP·TOKEN as an example.
Go to [UniCross](https://unicross.xyz) and connect your wallet.
1. Select the Phantom interface.
2. Click on the Bitmap - THE·BITMAP·TOKEN Pool.
3. Select the Bitmap you want to exchange for THE·BITMAP·TOKEN.
4. Click "Swap" and approve the transaction.
**Note**: EVM wallet users need to **initiate two transactions**: **one for authorization and one for the actual swap**. After authorizing, EVM wallet users will need to click "Swap" again to complete the transaction.
Additionally, after exchanging your Bitmap for THE·BITMAP·TOKEN, ownership of the original NFT will change. Even if you later use THE·BITMAP·TOKEN to reverse the exchange, you will receive a random Bitmap from the market circulation, and **it’s unlikely that you’ll get back your original NFT**. Therefore, owners of rare plots are advised not to use Merlin Phantom for Bitmap-to-token swaps.

## 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://docs.merlinchain.io/merlin-docs/user-quick-start/how-to/merlin-phantom/detailed-guides.md?ask=&goal=
```
`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.
