@Samarth1719 what's does it say at https://github.com/edent/SuperTinyIcons/blob/master/CONTRIBUTING.md#hacktoberfest---important

You need to actually read the README and the Contributing Guidelines.

@edent I am beginner in this contribution so just I am trying to understand the environment

@Samarth1719 It is very simple. You need to read.

The README file contains concise instructions. It tells you to read the CONTRIBUTING document.

You need to read both of these. That's the same for every project on GitHub. Read first, then ask questions if you don't understand something.
