1) Generate a private key and certificate signing request:

openssl genrsa -out ios_distribution.key 2048
openssl req -new -key ios_distribution.key -out ios_distribution.csr -subj '/emailAddress=me@example.com, CN=Example, C=US'

2) Upload CSR to apple at: https://developer.apple.com/account/ios/certificate/create
   - choose Production -> App Store and Ad Hoc

3) Download the resulting ios_distribution.cer, and convert it to .pem format:

Using git-submodules to version-control Vim plugins

If you work across many computers (and even otherwise!), it's a good idea to keep a copy of your setup on the cloud, preferably in a git repository, and clone it on another machine when you need. Thus, you should keep the .vim directory along with your .vimrc version-controlled.

But when you have plugins installed inside .vim/bundle (if you use pathogen), or inside .vim/pack (if you use Vim 8's packages), keeping a copy where you want to be able to update the plugins (individual git repositories), as well as your vim-configuration as a whole, requires you to use git submodules.

Creating the repository

Initialize a git repository inside your .vim directory, add everything (including the vimrc), commit and push to a GitHub/BitBucket/GitLab repository:

cd ~/.vim

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
