I'm bad at writing a fluent and correct English : deal with it !
To say it another way : all contributions (even the smallest ones) are welcomed and will be happily reviewed, as long as they have other purpose than boost your stats for Hacktoberfest by correcting typos, deleting supernumerary spaces in code, reformating text, adding unnecessary documentation or code, etc
To avoid working for nothing, you should really submit a discussion or an issue (if you want to correct a bug) explaining why you want to contribute and what is your proposal of contribution.
- Fork the repo
- Create a new branch in the forked repo
- Do your modifications to the code
- Test and verify your code
- Push a pull request to the original repo
- Wait for the code review (generally in less than a day)
