Instead of working directly on the main branch, create separate branches for new features or bug fixes. This ensures your main codebase remains stable while you work on changes.
3. Regularly Pull Changes from the Remote Repository
Before starting any new work, make a habit of pulling the latest changes from the remote repository to avoid conflicts. Use:
git pull origin main
4. Collaborate Using Pull Requests
When your changes are ready, open a pull request to suggest merging your branch into the main branch. This is also a good opportunity for code reviews from your peers.
Troubleshooting Common Issues
While connecting GitHub to your terminal is usually straightforward, you might encounter some challenges. Here are some common problems and their solutions:
1. Authentication Issues
If you face authentication issues, confirm that your SSH key is added correctly to your GitHub account. You can also try re-generating your SSH key if necessary.
2. Permissions Denied (Publickey)
This error often indicates that your SSH key isn’t being used. Check that your SSH agent is running and that you’ve added the correct SSH key.
