Create a new branch called feature1, make some changes to it, and merge it back into the main branch. Ensure there are no merge conflicts.

Here’s how to create a new branch called feature1, make changes in it, and then merge it back into the main branch without any merge conflicts:

Step 1: Create a New Branch

Make sure you're in your project directory (the one you initialized as a Git repository).
Create a new branch called feature1:
```
 git checkout -b feature1
```

Step 2: Make Some Changes

Open a file (e.g., README.md) in your text editor and make some changes. For example, you can add a new line:
```
 ## Feature 1 Implementation
 This section describes the implementation of feature 1.
```
Save the changes.
Add the modified file to the staging area:
```
 git add README.md
```
Commit the changes in the feature1 branch with a meaningful message:
```
 git commit -m "Add feature 1 description to README"
```

Step 3: Switch Back to the Main Branch

Switch back to the main branch:
```
 git checkout main
```

Step 4: Merge the Feature Branch

Merge the feature1 branch into the main branch:
```
 git merge feature1
```

Step 5: Verify the Merge

Open the README.md file again to ensure the changes from feature1 have been merged into main.

Step 6: Clean Up (Optional)

If you no longer need the feature1 branch, you can delete it:
```
 git branch -d feature1
```

Summary

You’ve successfully created a new branch, made changes in it, and merged those changes back into the main branch without any merge conflicts. If you have any questions or run into issues, feel free to ask!
