Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules directory) as well as files that are generated (and regenerated) as artifacts of a build process.

All other files should be in your own global gitignore file. Create a file called .gitignore in your home directory and add anything you want to ignore. You then need to tell git where your global gitignore file is.

Mac

git config --global core.excludesfile ~/.gitignore

Windows

git config --global core.excludesfile %USERPROFILE%\.gitignore

Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of advantages of using submodules:

You can separate the code into different repositories.

You can download whole courses from an array of tutorial sites with the CLI tool youtube-dl. In the example further down I'm using my Pluralsight account to get videos from a course at their site. Here is a list of all supported sites that you can download from with this tool

The flags you have to supply may vary depending on which site you make a request to.
