LTC-Lightning-Network-lnd-Guide

This is a step-by-step main net tutorial on how to setup a Lightning Network node for Litecoin on a Mac. It is specifically for the lnd client by the Lightning Labs. You can copy and paste most of the commands except for the times I've indicated in bold for you to input your own information. It would also be a good idea to backup your computer prior to starting just in case you need to start over.

Below is a legend. Refer to it as you come across terms or symbols you don’t understand. The first part of the tutorial is taken from the lnd github. However, everything else is written with the help of Patrick Walters taking me step by step through the process.

Legend

$ = This symbol means 1 line of code. Do not type “$” into your terminal. Simply input what follows then push enter.

Pubkey = Short for the public key that is generated from the private key w

If you are like me you find yourself cloning a repo, making some proposed changes and then deciding to later contributing back using the GitHub Flow convention. Below is a set of instructions I've developed for myself on how to deal with this scenario and an explanation of why it matters based on jagregory's gist.

To follow GitHub flow you should really have created a fork initially as a public representation of the forked repository and the clone that instead. My understanding is that the typical setup would have your local repository pointing to your fork as origin and the original forked repository as upstream so that you can use these keywords in other git commands.

Clone some repo (you've probably already done this step).
```
git clone [email protected]
```
