# Contributing
Thank you for wanting to contribute to the development for theta! Please keep the following in mind when contributing to this repository please keep all of the following in mind as it will prevent headaches in the future
## Code style
- Constants are to be written using SCREAMING_SNAKE_CASE
- Classes are to be written using PascalCase
- Functions/Variables are written in camelCase
- Define variables using `let` and not `var`
- Use undefined over null
## Creating a pull request
- When making changes please fork and submit a pull request
- Please outline every change made in this pull request, to make the maintainers' job easier
- Discussion within pull requests regarding implementation details is always healthy
- Once a maintainer agrees your pull request shall be squashed and merged!
