Human readable linelength for issues/readme/etc
I already mentioned this in another issue, but I thought let's make this an issue on itself.
Lets get the line length of reading text sections needed to be read by humans into better shape! Its bad typography practice to have to read text at incredibly long lines, see practical typography for reference.
Of course this should be applied sensibly and only to the parts that contain real texts.
Here are two examples with the following code applied:
.container-limited{
max-width: 800px;
}
