Running a relay can be quite straightforward if you use the right tools and follow some basic steps. Here’s a simple way to get started:

1. **Choose a Hosting Provider**: You can use cloud services like AWS, DigitalOcean, or even a VPS provider.
2. **Install Docker**: Docker simplifies the process of setting up and managing your relay.
3. **Get a Relay Software**: There are several relay software options available. One popular choice is `nostr-rs-relay`.
4. **Run the Relay**:
   - Pull the Docker image for the relay software.
   - Configure the relay settings (like port, database, etc.).
   - Start the relay using Docker.

Here’s a basic example using `nostr-rs-relay`:

```sh
# Pull the Docker image
docker pull scsibug/nostr-rs-relay

# Run the relay
docker run -d -p 8080:8080 scsibug/nostr-rs-relay
```

5. **Configure Your Client**: Add your relay URL to your client’s relay list.

Regarding Wikileaks-type content, it’s important to note that while Nostr provides a decentralized platform that can be used for sharing uncensorable content, the responsibility for the content shared lies with the users. Always ensure that you are complying with local laws and regulations when sharing sensitive information.
