+# Contribution Guidelines
+
+Thank you for considering contributing to the Bash Prompt Generator.
+This document will help you with the first steps.
+If anything is unclear, feel free to ask for help or clarification via an [issue](https://github.com/Scriptim/bash-prompt-generator/issues/new?template=question.yml "Ask a question").
+
+## Reporting a Bug or Requesting a Feature
+
+If you found a bug or have an idea for a new feature, please open an [issue](https://github.com/Scriptim/bash-prompt-generator/issues/new "Open a new issue").
+The issue templates will guide you through the process.
+Please always confirm that the issue you are about to open does not already exist.
+
+## Contributing Code
+
+Before you start working on the code, please open an [issue](https://github.com/Scriptim/bash-prompt-generator/issues/new "Open a new issue") to discuss the bug or feature you want to work on.
+This way, you can ensure that your contribution is in line with the project's goals and that you are not working on something that is already in progress.
+Otherwise, your pull request might be rejected, and I do not want you to waste your time.
+For very minor changes, e.g., fixing a typo, you can skip this step.
+
+When you are ready to contribute, fork the repository, create a branch for your changes, and open a pull request.
+If you are not familiar with these steps, refer to this [guide](https://opensource.guide/how-to-contribute/#opening-a-pull-request "How to Contribute to Open Source").
+Feel free to open a draft pull request if you need help or feedback early on.
+Before finalizing your pull request, make sure to follow the instructions in the pull request template.
+
+### Setup Development Environment
+
+To set up your development environment, you need to have [Node.js](https://nodejs.org/ "Node.js") installed.
+After cloning your fork, navigate to the project directory and run `npm install` to install the required dependencies.
+You can the run `npm run serve` to start the development server which make the Bash Prompt Generator available locally.
+Any changes you make to the source code should immediately be reflected in the browser.
+Before committing your changes, run `npm run lint` to verify the code style.
+
+### Commit Messages
+
+The subject line of your commit message should be capitalized, not exceed 50 characters, not end in punctuation and be written in the imperative mood.
+Feel free to include a body to provide more context or explain the reasoning behind your changes.
+
+### Code Review
+
+All contributions will be reviewed before they are merged.
+Please be patient since this process might take some time.
+The project is currently maintained by a single person, and there is no fixed schedule for reviewing pull requests.
