# Prerequisites

Before interacting with Private Tokens, make sure your setup is complete.

1. **Install MetaMask**

   Install the [MetaMask](https://metamask.io/download) extension in your browser. This will serve as your wallet for interacting with the COTI network.
2. **Add the COTI Network**

   Once MetaMask is installed, add the COTI network you will use: [COTI Testnet](/coti-documentation/networks/testnet/adding-the-coti-testnet-to-metamask.md) or [COTI Mainnet](/coti-documentation/networks/mainnet/adding-the-coti-mainnet-to-metamask.md). If the network is not already configured, the Privacy Portal can prompt you to add it.
3. **Install the COTI Snap**

   Install the COTI Snap in MetaMask. The COTI Snap is essential for handling Private Tokens within MetaMask. Follow the [installation instructions](/coti-documentation/coti-privacy-portal/user-guide/metamask-snap-setup.md) to configure it properly. It enables encryption, decryption, and key management for private token operations.
4. **Fund your wallet**

   Make sure your wallet has enough native COTI to cover transaction fees.

## 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.coti.io/coti-documentation/coti-privacy-portal/user-guide/prerequisites.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.
