 ## How to mine on P2Pool
 
-This guide assumes that you run everything on the same machine. If it's not the case, change `127.0.0.1` to appropriate IP addresses for your setup. It's highly recommended to create a new mainnet wallet for mining because **wallet addresses are public on p2pool**.

-- Cake Wallet v4.2.7 and newer
-- Feather Wallet v1.0.0 and newer
-- MyMonero
+- In order to mine on P2Pool, a synced Monero node using monerod v0.17.3.0 or newer is required. If you do not currently have one configured, you can find instructions to do so [here](https://sethforprivacy.com/guides/run-a-monero-node-advanced/).
+- It is highly recommended that you create a separate restricted user account for mining. P2Pool is still relatively new and may still have serious bugs/vulnerabilities. 
+- You have to use a primary wallet address for mining. Subaddresses and integrated addresses are not supported, just like with monerod solo mining.
+- Starting from P2Pool v1.7, 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.

 ### GNU/Linux
 
-- Download binaries from https://github.com/SChernykh/p2pool/releases/latest
-- Alternatively, grab the latest source code for p2pool and build it
-- Prepare enough huge pages (each of monerod/p2pool/xmrig needs them): `sudo sysctl vm.nr_hugepages=3072`
-- Get xmrig (linux-static-x64) binary from https://github.com/xmrig/xmrig/releases/latest
-- Check that ports 18080 (Monero p2p port) and 37889 (p2pool p2p port) are open in your firewall to ensure better connectivity
-- Use the `monerod` binary v0.17.3.0 or newer
-- Run `./monerod --zmq-pub tcp://127.0.0.1:18083 --disable-dns-checkpoints --enable-dns-blocklist` **don't forget --zmq-pub parameter in the command line**
-- Run `./p2pool --host 127.0.0.1 --wallet YOUR_WALLET_ADDRESS`
-- p2pool has verbose logging by default, you can reduce it by using "loglevel N" command where N is between 0 and 6. Default loglevel is 3.
-- You can use `logrotate` with a config like this to control logfile growth:
-    ```
-    <path-to-logfile>
-    {
-	    rotate 7
-	    daily
-	    missingok
-	    delaycompress
-	    nocreate
-    }
-    ```
-- Wait until initial p2pool sync is finished, it shouldn't take more than 5-10 minutes, once completed xmrig should be able to connect to the stratum server on port 3333.
-- Run `./xmrig -o 127.0.0.1:3333`. Note that you don't need to specify wallet address for xmrig. **Wallet address set in xmrig config will be ignored!**
-- To set custom fixed difficulty for your miner (for example, 10000), run `./xmrig -u x+10000 -o 127.0.0.1:3333`
-- xmrig should connect and start mining
-- Also check p2pool.log for any warnings and errors: `grep -E 'WARNING|ERROR' p2pool.log`

+``` 
+**Note:** The `--zmq-pub` option is required for P2Pool to work properly.
+
+6. Start P2Pool with the following command/options:
+```
+./p2pool --host 127.0.0.1 --wallet YOUR_WALLET_ADDRESS
+```
+7. Wait until the initial P2Pool sync is finished (shouldn't take more than 5-10 minutes).
+8. Start XMRig with the following command/options:
+ ```
+ ./xmrig -o 127.0.0.1:3333
+ ```
+   - Note that you don't need to specify your wallet address for XMRig. **Wallet addresses set in XMRig config will be ignored!** 
+   - To set a custom fixed difficulty for your miner (for example, 10000), instead start XMRig with the following options: 
+   ```
+   ./xmrig -u x+10000 -o 127.0.0.1:3333
+   ```
