README, explained simply
The README is like the instruction sheet that comes in the box. On GitHub, it shows on the repo's main page.
A good one covers what the tool does, how to install it, and how to try it.
It is the best place to start. Read it before you download or run anything.
It is often written in Markdown, a simple way to format text.
On ITG Now, our free tool guides turn each project's README into plain steps, so you don't have to read the technical parts.

Questions people ask about README
Is the README the same as documentation?
A README is the short front page. Bigger projects also have fuller documentation elsewhere.
What should I look for in a README?
Look for what the tool does, how to install it, and a license. Clear steps are a good sign.
Can I trust everything in a README?
Not blindly. Anyone can write one, so check that the repo is the real one.
