## Contribution Guidelines
[![GitHub code size in bytes](https://img.shields.io/github/languages/code-size/ramanaditya/data-structure-and-algorithms?logo=github)](https://github.com/ramanaditya/data-structure-and-algorithms/) 
[![GitHub commit activity](https://img.shields.io/github/commit-activity/m/ramanaditya/data-structure-and-algorithms?color=blue&logo=github)](https://github.com/ramanaditya/data-structure-and-algorithms/commits/) 
[![GitHub repo size](https://img.shields.io/github/repo-size/ramanaditya/data-structure-and-algorithms?logo=github)](https://github.com/ramanaditya/data-structure-and-algorithms/)
[![PRs Welcome](https://img.shields.io/badge/PRs-welcome-brightgreen.svg?style=flat&logo=git&logoColor=white)](https://github.com/ramanaditya/data-structure-and-algorithms/pulls)

- Write clear meaningful git commit messages (Do read [this](http://chris.beams.io/posts/git-commit/)).

- Make sure your PR's description contains GitHub's special keyword references that automatically close the related issue when the PR is merged. (Check [this](https://github.com/blog/1506-closing-issues-via-pull-requests) for more info)

- When you make very very minor changes to a PR of yours (like for example fixing a text in button, minor changes requested by reviewers) make sure you squash your commits afterward so that you don't have an absurd number of commits for a very small fix. (Learn how to squash at [here](https://davidwalsh.name/squash-commits-git))

- When you're submitting a PR for a UI-related issue, it would be really awesome if you add a screenshot of your change or a link to a deployment where it can be tested out along with your PR. It makes it very easy for the reviewers and you'll also get reviews quicker.

- Please follow the [PR Template](https://github.com/ramanaditya/data-structure-and-algorithms/blob/main/.github/PULL_REQUEST_TEMPLATE.md) to create the PR.

- Always open PR to `develop` branch.

- Please read our [Code of Conduct](./CODE_OF_CONDUCT.md).

- Refer [this](https://github.com/ramanaditya/data-structure-and-algorithms/blob/main/CONTRIBUTING.md) for more.
