Pull requests that are merged into master can then be pushed into the Patch Chain by you or a [Maintainer](superprotocolo://c4b014e8d2c1c6769ac45dc6a27e28048f6b89edfe49b9f4434ba3216cf9451d)."

Download the latest Mindmachine tip from below or the [github mirror](https://github.com/Stackerstan/mindmachine) \n2. `make run` and wait for it to reach the current Bitcoin height\n3. Clone the [interfarce](https://github.com/Stackerstan/interfarce) and replace  .\n4. If something goes wrong: `make reset`\n"
    let p = "#### How to send a Patch the difficult way \nThis is clunky and buggy because Stackerstan doesn't use Git and instead uses it's own built-in and very pre-alpha Version Control System called the Patch Chain, which is included in OP_RETURN states.\n\n1. Edit `cliListener.go` \n\n---\n2. Find \"o\" and replace the hash with the UID of a Problem you have Claimed\n\n---\n3. Press \"o\" in the CLI.\n\n A working directory will be printed in the CLI, open it in your favourite IDE.\n\n---\n4. Solve the Problem with the least amount of changes possible but leave anything you modify *easier to reason about than before you started touching it*.\n\n---\n5. Run `make reset` to sync with the network and make sure your changes didn't break anything.\n\n---\n6. Edit `cliListener.go` again and find \"l\". \n\n    Replace the hash with the UID of the problem you are solving.\n\n---\n7. **Backup your modifications**, the next step is buggy and you might be about to lose them all.\n\n---\n8. Put your seatbelt on, make sure it's tight and secure. If you're fat you'll probably want a full harness.\n\n Press \"l\" in the CLI and save the output that's printed so that you can figure out what's broken.\n\n If it worked (20% chance), you'll see your Patch in the Interfarce ready to be Merged by a Maintainer. If it didn't, there's a bug and you'll probably want to ask for help in the Samizdatree or something."
