GitHub supports several lightweight markup languages for documentation; the most popular ones (generally, not just at GitHub) are Markdown and reStructuredText. Markdown is sometimes considered easier to use, and is often preferred when the purpose is simply to generate HTML. On the other hand, reStructuredText is more extensible and powerful, with native support (not just embedded HTML) for tables, as well as things like automatic generation of tables of contents.

Suppose you have, by mistake, added your IDE's project folder (you know, these .idea
folders with all kinds of local paths and configuration data and settings in it) to the Git repository of your project. (We're talking about a whole folder here, but the same rules apply to individual files as well.)
Of course, you only realize that two days after the fact and have already pushed it, and your colleagues have already pulled it. They use the same IDE as you do, so whenever they change a setting or fix paths, they can either
- commit that, causing nasty merge conflicts for you and others or
- ignore the changes and carry around a modified file until the end of time without ever committing it.
