Q&A

• Why is writing good commit messages important?

  Writing good commit messages is important because it makes it easier for humans to understand the changes introduced in each commit. Clear and descriptive commit messages improve code review, collaboration, and project maintenance.

• How do I resolve merge conflicts in Git?

  Merge conflicts in Git can be resolved by manually selecting the code to keep or discard. This involves carefully reviewing the conflicting code and making decisions on how to integrate the changes.

• How do I create a pull request on GitHub?

  To create a pull request on GitHub, first, push your changes to a feature branch, then go to the GitHub repository, click on the 'New pull request' button, compare changes, and create the pull request for review and merging.

• What is branching in Git?

  Branching in Git allows developers to work on code changes in separate areas before merging them back into the main branch. This is useful for collaboration, experimentation, and dealing with different features or bug fixes.

• What are SSH keys and how do I set them up for GitHub?

  SSH keys are a secure way to authenticate and communicate with remote servers like GitHub. To set up SSH keys for GitHub, you can generate SSH keys on your local machine and add the public key to your GitHub account.

• How do I stage and commit changes in Git?

  To stage and commit changes in Git, use the 'git status' command to check for untracked and modified files, then use 'git add' to stage changes, and 'git commit -m' to commit the changes with a descriptive message.

• What is Markdown and how is it used in Git and GitHub?

  Markdown is a lightweight markup language used for formatting text. In the context of Git and GitHub, it provides an easy way to format files and documentation, making them visually appealing and well-structured.

• How do I set up a GitHub account and create a new repository?

  To set up a GitHub account, go to the GitHub website and follow the registration process. After creating an account, you can create a new repository by clicking on the 'New' button on your GitHub profile and following the prompts.

• What are the basic Git commands?

  The basic Git commands include clone, add, commit, push, and pull. These commands are essential for managing code changes and collaborating on projects using Git and GitHub.

• What is GitHub?

  GitHub is a web-based platform for hosting Git repositories online. It facilitates collaboration, project organization, and version control.

• What is Git?
