+```
+and on the Tari side
+```
+./minotari_node --grpc-enabled --mining-enabled

+TARI_NODE_IP is 127.0.0.1 if you run both on the same machine (recommended).
+
+Merge mining is available on Tari's mainnet:
+- Download [Tari suite](https://github.com/tari-project/tari/releases/latest) for your OS
+- Run Minotari node and wait until in synchronizes
+- Run Minotari console wallet to create a Tari wallet
+- Copy the interactive wallet address from the "Receive" tab of the wallet
+- Paste it into the P2Pool command line above
+- Everything is ready now to start merge mining Monero and Tari!
+
+Note that Tari will be mined in solo mode (only full Tari blocks can be mined for now). This doesn't affect P2Pool payouts - they will stay the same.

 Only 64-bit builds are supported, in particular ARMv7 or older CPUs are not supported. The reason is that RandomX hashing algorithm is too slow in 32-bit mode, and P2Pool needs to check new blocks very fast to keep up with other nodes.

+Starting from v4.6, P2Pool will also have an ability to merge mine donations for the author.
+
+Note that this will not affect your hashrate or payouts in any way. P2Pool will always (100% of the time) keep mining to your configured Monero wallet address, but it might also use the available merge mining capacity to donate to the author.
+
+If you merge mine yourself, your settings will take priority.
+
+The merge mining donation runs without a donation server - there is no "phoning home" to a server, everything is done through the P2Pool's network in a decentralized way.
+
+To opt out of this, build P2Pool with `-DWITH_MERGE_MINING_DONATION=OFF` in cmake command line. Due to the architecture of the decentralized P2Pool network, your node will still relay donation messages to other nodes even if you opted out (but it will not process them).

+### Merge mining
+
+Merge mining is available in P2Pool since the fork that happened on October 12th, 2024. Version 4.0 or newer is required to use it.
+
+- Blockchains that will support [Merge mining RPC API](https://github.com/SChernykh/p2pool/blob/master/docs/MERGE_MINING.MD#proposed-rpc-api)
+  - [Townforge](https://townforge.net/) supports it in their [tmp-mm branch](https://git.townforge.net/townforge/townforge/src/branch/tmp-mm) (not released yet)
+  - [DarkFi](https://dark.fi/) is going to support it, but it's [not ready yet](https://github.com/darkrenaissance/darkfi/issues/244)
+  ```
+  p2pool.exe --wallet YOUR_MONERO_WALLET_ADDRESS --merge-mine IP:port YOUR_WALLET_ADDRESS_ON_ANOTHER_BLOCKCHAIN
+  ```
+
+### Tari merge mining
+
+[Tari](https://www.tari.com/) uses their own gRPC API and requires a different command line:
+```
+./p2pool --wallet YOUR_MONERO_WALLET_ADDRESS --merge-mine tari://TARI_NODE_IP:18102 TARI_WALLET_ADDRESS
+```
+and on the Tari side
+```
+./minotari_node --grpc-enabled --mining-enabled
+```
+TARI_NODE_IP is 127.0.0.1 if you run both on the same machine (recommended).
+
+Merge mining is available on Tari's mainnet:
+- Download [Tari suite](https://github.com/tari-project/tari/releases/latest) for your OS
+- Run Minotari node and wait until in synchronizes
+- Run Minotari console wallet to create a Tari wallet
+- Copy the interactive wallet address from the "Receive" tab of the wallet
+- Paste it into the P2Pool command line above
+- Everything is ready now to start merge mining Monero and Tari!
+
+Note that Tari will be mined in solo mode (only full Tari blocks can be mined for now). This doesn't affect P2Pool payouts - they will stay the same.
+
+### TLS
+
+Starting from v4.1, P2Pool supports SSL/TLS connections to its Stratum port. Port 443 can also be safely used for Stratum connections since v4.1 - P2Pool will detect HTTP requests and respond to them.
+
+All `--tls...` parameters are optional. If they are not provided, P2Pool will generate a self-signed certificate upon startup.
+
+If you want to use your own certificate, please refer to your certificate provider's documentation (or OpenSSL documentation) on how to generate the appropriate PEM files.
+
+Note that you need to use certificate files and `--tls...` parameters to be able to use certificate pinning in XMRig miners that connect to your P2Pool instance.
+
+`--tls-cert` and `--tls-cert-key` parameters must always be used together.
+
+### RPC-SSL
+
+Starting from v4.4, P2Pool supports RPC-SSL connections to Monero nodes. Add `--rpc-ssl` to P2Pool command line to enable it.
+
+P2Pool supports certificate pinning on RPC-SSL connections via `--rpc-ssl-fingerprint MONERO_NODE_FINGERPRINT_BASE64` parameter. To get your node certificate's fingerprint, run
+
+```
+openssl x509 -in rpc_ssl.crt -pubkey -noout -inform pem | openssl pkey -pubin -outform der | openssl dgst -sha256 -binary | openssl enc -base64
+```
+
+By default, `rpc_ssl.crt` can be found in Monero data directory: `/home/username/.bitmonero/rpc_ssl.crt` on Linux and `C:\ProgramData\bitmonero\rpc_ssl.crt` on Windows.

+
+## Merkle tree parameters
+
+A 64-bit value encoding the total number of aux chains hashed into the Merkle root hash, and an aux nonce that defines the order of aux chains when building the Merkle tree.
+
+Bit|Description
+-|-
+0...2|`N-1` - number of bits used to store `n_aux_chains` (value 0 means 1 bit, ..., value 7 means 8 bits)
+3...`N`+2|`n_aux_chains-1` (value 0 means 1 chain, and so on)
+`N`+3...`N`+34|`aux_nonce` (32-bit value)
+`N`+35...63|reserved (current implementations must set these bits to all 0 when writing and ignore these bits when reading)
+
+`N` must be the smallest number of bits enough to represent `n_aux_chains-1`
+
+Reference code: `PoolBlock::encode_merkle_tree_data` and `PoolBlock::decode_merkle_tree_data` in `pool_block.h`
+
+## Merkle tree construction's first step (Monero-specific)
+
+If `n_aux_chains` is not a power of 2, their hashes are combined starting from the end of the list of hashes until there are a power of 2 hashes left. Then they're processed normally.
+
+Example 1: 6 hashes `H0, H1, H2, H3, H4, H5` will be transformed into 4 hashes `H0, H1, H(H2|H3), H(H4|H5)` where `H` is the hash function and `|` is concatenation.
+
+Example 2: 5 hashes `H0, H1, H2, H3, H4` will be transformed into 4 hashes `H0, H1, H2, H(H3|H4)`
+
+## The order of hashes in the Merkle tree
+
+Each of the aux chains must provide a 32-byte value `unique_id` that singles it out from any other chain. Genesis block's hash is a good choice for this value, but it can be anything else really.
+
+`unique_id` is used to enforce the order in which aux hashes are added to the Merkle tree. This prevents an attack where miners can mine two versions of the same chain (for example when double spending) without any additional cost.
+
+Forked chains can choose whether to keep their `unique_id` or change it. If they keep it, it will be impossible to merge mine with the chain they forked from beause they will always be assigned the same slot in the Merkle tree.
+
+A deterministic pseudo-random function `SHA256(unique_id|nonce|"m") % N` is applied to determine which slot is used by which chain. `nonce` is brute-forced until all `N` chains are assigned different slots. This limits `N` to no more than 15-16 in practice.
+
+Reference code: `get_aux_slot` and `find_aux_nonce` in `merkle.cpp`

+`aux_blob`|A hex-encoded blob of data. Merge mined chain defines the contents of this blob. It's opaque to P2Pool and will not be changed by it.
+`aux_diff`|Mining difficulty (decimal number).
+`aux_hash`|A 32-byte hex-encoded hash of the `aux_blob`. Merge mined chain defines how exactly this hash is calculated. It's opaque to P2Pool.
+
+If `aux_hash` is the same as in the request, all other fields will be ignored by P2Pool, so they don't have to be included in the response. Moreover, empty response will be interpreted as a response having the same `aux_hash` as in the request. This enables an efficient polling.
