How to squash commits in a GitHub pull request

o you've contributed some code to an open source project, say, Rails. And they'd like you to squash all of the commits in your pull request. But you're not a git wizard; how do you make this happen?

Normally, you'd do something like this. I'm assuming upstream is a git remote that is pointing at the official project repository, and that your changes are in your 'omgpull' branch:

dakk

# Install lisk-commander
$ sudo npm install --global --production lisk-commander

# Transaction creation
$ lisk transaction:create -t transfer 100 ADDRESSL

# Broadcast the multisig tx

// First install bitcoinjs-lib and bip39 in the current working directory
//   npm install bitcoinjs-lib bip39

const bitcoin = require ('bitcoinjs-lib');
const bip39 = require ('bip39');

/// Generate a random keypair and display private and public key and the address (compressed by default)
let keypair = bitcoin.ECPair.makeRandom ();

console.log ('Address:', keypair.getAddress());
