Git comes with a tool called git config that lets you get and set configuration variables that control all aspects of how Git looks and operates. These variables can be stored in three different places:

.1 /etc/gitconfig file $ \Rightarrow $ Contains values for every user on the system and all their repositories. If you pass the option --system to git config, it reads and writes from this file specifically.

.2 ~/.gitconfig or ~/.config/git/config file $ \Rightarrow $ Specific to your user. You can make Git read and write to this file specifically by passing the –global option.

.3 config $ \Rightarrow $ file in the Git directory (that is, .git/config) of whatever repository you’re currently using: Specific to that single repository.

$ git config --global user.name "John Doe"
$ git config --global user.email johndoe@example.com
$ git config --global color.ui auto
$ git clone https://github.com/RoscaS/RoscaS.github.io

Mermaid

Embed charts in jekyll

Download js code of mermaid: mermaid. ATM, the file is hosted here but it might change after update. We want the file named mermaid.min.js.
Put this file into a folder named js in the root of the website.

Open /_includes/head.html and add this line:

<script src="/js/mermaid.min.js"></script>

Now we can make nice graphs like this one:

graph TD; A-->B; A-->C; B-->D; C-->D;

<div class="mermaid">
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;
</div>

We just need to put the graph code inside <div class="mermaid">...</div> tags.
