 ### General Considerations
 
 - In order to mine on P2Pool, a synced Monero node using monerod v0.18.0.0 or newer is required. If you don't currently have one, you can download the [official Monero binaries](https://www.getmonero.org/downloads/), start `monerod` on your PC and wait until it's fully synced. Advanced Monero node setup instructions are [here](https://sethforprivacy.com/guides/run-a-monero-node-advanced/).
-- It is highly recommended that you create a separate restricted user account (in your OS) for mining. While P2Pool has been battle-tested for a long time now, any software may have unknown bugs/vulnerabilities. 
-- You have to use a primary wallet address (the one starting with `4`) for mining. Subaddresses and integrated addresses are not supported, just like with monerod solo mining.
-- You can add the `--mini` parameter to your P2Pool command to connect to the **p2pool-mini** sidechain. Note that it will also change the default p2p port from 37889 to 37888.
-- Check that ports 18080 (Monero p2p port) and 37889/37888 (P2Pool/P2Pool mini p2p port) are open in your firewall to ensure better connectivity. If you're mining from a computer behind NAT (like a router) you could consider forwarding the ports to your local machine.

+## Running P2Pool with I2P
+
+P2Pool has several command-line options that should be used for I2P setup:
+
+- `--socks5 IP:port` to specify your I2P SOCKS proxy address (usually `127.0.0.1:4447` if you are using i2pd or followed the guide below)
+- `--socks5-proxy-type i2p` to specify the type of SOCKS5 proxy being used
+- `--no-dns` to disable all DNS queries and prevent DNS leaks. P2Pool only ever makes DNS requests to get a list of seed nodes, to resolve your Monero node's domain (if it's not set as an IP address), and to resolve manually added peers
+- `--no-upnp` to disable UPnP requests (they are sent to your router, so use this option if you are not on your home network)
+- `--i2p-address` your hidden service's `.b32.i2p` address (without port number). This address will be broadcast to other peers when you mine a share in P2Pool. This is to prevent address spamming - you have to mine a real share to be able to broadcast your I2P address.
+	- **Attention: this also links the I2P address with the Monero wallet you use for mining. Create a new I2P address when mining through I2P, don't use your existing addresses to avoid metadata leaks.**
+- `--no-clearnet-p2p` to never connect to clearnet P2Pool nodes.
+
+## Setting up I2P tunnels for P2Pool (i2pd on Linux)
+
+Follow [these instructions](https://docs.i2pd.website/en/latest/user-guide/install/) to install i2pd on your system.
+First, ensure the SOCKS proxy tunnel is enabled (as it should be by default). See [here](https://docs.i2pd.website/en/latest/user-guide/configuration/) for more information.
+
+You will need to modify some lines in the `tunnels.conf` file, usually located in `/var/lib/i2pd/tunnels.conf` on Linux.
+Add a server tunnel to allow inbound connections from peers:
+```ini
+[p2pool]
+type = server
+host = 127.0.0.1
+port = 28723
+keys = p2pool.dat
+```
+This will create a hidden service key in `/var/lib/i2pd/p2pool.dat`; you may want to back this up.
+Please note that you **must** use the port number shown above in order for other peers to be able to find you.
+
+Restart i2pd:
+```bash
+sudo systemctl restart i2pd.service
+```
+
+Get the hostname of your hidden service:
+```bash
+curl -s http://127.0.0.1:7070/?page=i2p_tunnels | grep -Eo "[a-zA-Z0-9./?=_%:-]*" | grep "28723"
+```
+
+The resulting `.b32.i2p` address should then be used for the `--i2p-address` command-line parameter.
+
+## Command line example
+```bash
+./p2pool --host MONERO_NODE_IP --wallet YOUR_WALLET --socks5 127.0.0.1:4447 --socks5-proxy-type i2p --no-dns --no-upnp --i2p-address YOUR_I2P_ADDRESS

+## Running P2Pool with TOR

+P2Pool has several command-line options that should be used for TOR setup:
+
+- `--socks5 IP:port` to specify your TOR proxy address (usually `127.0.0.1:9050` if you installed TOR on the same PC)
+- `--socks5-proxy-type tor` to specify the type of SOCKS5 proxy being used
+- `--no-dns` to disable all DNS queries and prevent DNS leaks. P2Pool only ever makes DNS requests to get a list of seed nodes, to resolve your Monero node's domain (if it's not set as an IP address), and to resolve manually added peers

+	- **Attention: this also links the onion address with the Monero wallet you use for mining. Create a new onion address when mining through TOR, don't use your existing onion addresses to avoid meta-data leaks.**
+- `--no-clearnet-p2p` to never connect to clearnet P2Pool nodes. This also makes sure that your P2Pool traffic doesn't exit the TOR network (and is not seen/modified by the exit nodes)
+
+## Setting up a hidden service for P2Pool (Linux)
+
+- Add these lines to your TOR config in `/etc/tor/torrc`:
+	```
+	HiddenServiceDir /var/lib/tor/p2pool/
+	HiddenServicePort 28722 127.0.0.1:37889
+	```
+	Note that you must use port 28722 as the hidden service's port because this is what other peers will use when trying to connect to you. The internal port (37889) should be your actual P2Pool listening port (37889 for P2Pool-main, 37888 for P2Pool-mini, 37890 for P2Pool-nano)
+- Restart the TOR service:
+	```
+	sudo systemctl restart tor.service
+	```
+- If there were no errors, you should now have the `/var/lib/tor/p2pool` directory with a `hostname` file in it. This file will contain your onion address
+- Use this address in P2Pool's command line: `--onion-address ADDRESS_FROM_HOSTNAME_FILE`
+- It is strongly recommended to create a new onion address for mining (see `--onion-address` remarks). This guide ensures you will be using a new onion address, assuming that you don't already have a hidden service named `p2pool`.
+
+## Command line example
+```
+./p2pool --host MONERO_NODE_IP --wallet YOUR_WALLET --socks5 127.0.0.1:9050 --socks5-proxy-type tor --no-dns --no-upnp --onion-address ADDRESS_FROM_HOSTNAME_FILE
