+## Contribution Guidelines
+
+- **Star** the repository.
+- On the [GitHub page for this repository](https://github.com/Python-World/Py-Resources), click on the Button "**Fork**".
+   ![fork image](https://help.github.com/assets/images/help/repository/fork_button.jpg)
+- Create clone ***your forked repository*** on your local machine.
+   ![code ui](https://docs.github.com/assets/images/help/repository/code-button.png)
+
+    For example, run this command inside your terminal:
+
+    ```bash
+    git clone https://github.com/<your-github-username>/Py-Resources.git
+    ```
+
+    **Replace \<your-github-username\>!**
+
+    Learn more about [forking](https://help.github.com/en/github/getting-started-with-github/fork-a-repo) and [cloning a repo](https://docs.github.com/en/github/creating-cloning-and-archiving-repositories/cloning-a-repository).
+- Before you make any changes, [keep your fork in sync](https://www.freecodecamp.org/news/how-to-sync-your-fork-with-the-original-git-repository/) to avoid merge conflicts:
+
+    ```bash
+    git remote add upstream https://github.com/Python-World/Py-Resources.git
+    git fetch upstream
+    git pull upstream master
+    git push
+    ```
+
+- If you run into a **merge conflict**, you have to resolve the conflict. There are a lot of guides online, or you can try this one by [opensource.com](https://opensource.com/article/20/4/git-merge-conflict).
+
+- Checkout to development branch (*name your branch according to the issue name*).
+
+    ```bash
+    git checkout -b <branch-name>
+    ```
+
+- Create a folder in one of the folders in the [Scripts' directory](https://github.com/Python-World/Py-Resources/tree/master/Scripts) according to issue name.
+- Write your code and add to the respective folder in the projects directory, locally.
+- Add the changes with `git add`, `git commit` ([write a good commit message](https://chris.beams.io/posts/git-commit/), if possible):
+
+    ```bash
+    git add -A
+    git commit -m "<your message>"
+    ```
+
+- Push the code *to your repository*.
+
+    ```bash
+    git push origin <branch-name>
+    ```
+
+- Go to the GitHub page of _your fork_, and **make a pull request**:
+
+    ![pull request image](https://help.github.com/assets/images/help/pull_requests/choose-base-and-compare-branches.png)
+
+    Read more about pull requests on the [GitHub help pages](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request).
+- Now wait, until one of us *reviews your Pull Request*! If there are any conflicts, you will get a notification.
