1. Learned how to search for files in VSC. Need to use cmmd+P
2. The config.js is king
3. For the config.js stuff to come to an affect, you need to do gatsby develop again.
4. gatsby build doesn't work locally. Not sure what it does. ?????
5. The location of media assets are under the static/media not sure why it's in there. For more see https://www.gatsbyjs.com/docs/how-to/images-and-media/static-folder/

Great video on stdin vs stdout: https://www.youtube.com/watch?v=OsErpB0-mWY

stdin

As a standard your input usually comes from the keyboard. Ex cat file.txt. <- here you're passing file.txt as a parameter.

However you can do cat < $file_name i.e. make the input to the cat command a variable.

Both cat file.txt & cat < file.txt achieve the same, but through different mechanics. < is passing something as an input.

I suppose it's because the cat command has abilities to handle file names as arguments and through stdin

/*
ATTENTION: I've added two files here. 

Steps to find this yourself. 
1. Xcode >> Find >> New Scope >> Set the 'Search the following locations:' to SDK; Then set the other dropdown to 'iOS <whateverVersion>'

2. Then search for the error code number.

Find all file names that start with 'App'

find path/to/folder -name "App*"

Show the next 3 lines (trailing context) after a match

cat Foo.swift | grep -A 3 methodA

There are some nuances. Took me a bit to piece it all together.

1. Just add an if condition at the end of your existing global .gitconfig at your root directory.

[includeIf "gitdir:~/something/personal/"]
  path = .gitconfig-personal
[includeIf "gitdir:~/elsewhere/work/"]
  path = .gitconfig-work
