+# How to Resolve Merge Conflicts via Terminal (CLI Guide)
+
+This guide goes along with the GitHub web UI guide. Here, we will focus on fixing merge conflicts using Git in your terminal. Here's a step-by-step guide so beginners can follow easily. 
+
+### Step 1: Clone the Repository
+
+1. First, fork the repository on GitHub. Then clone your fork locally with this command:
+
+```bash
+git clone https://github.com/<your-username>/zoea-opensource.git
+```
+
+*Replace `<your-username>` with your GitHub username.*
+
+2. Move into the project directory:
+```bash
+cd zoea-opensource
+```
+
+### Step 2: Checkout the Conflict Branch
+
+1. Fetch all remote branches with the following command:
+
+```bash
+git fetch origin
+```
+
+2. Then switch to the branch assigned to you.
+```bash
+git checkout <conflict-branch-name>
+```
+*Replace `<conflict-branch-name>` with the branch provided in the issue comment*
+### Step 3: Merge Main into Your Branch
+
+Merge changes from the main branch into your conflict branch:
+
+```bash
+git merge main
+```
+    
+*Git will notify you if there are conflicts*
+    
+### Step 4: Identify Conflicts
+
+Check which files have conflicts and view what exactly is conflicting with:
+    
+```bash
+git status
+```
+
+To see the exact differences, use:
+```bash
+git diff
+```
+
+### Step 5: Resolve Conflicts
+
+Open the conflicted file in your text editor. You'll see markers like this:
+
+```bash
+<<<<<<< HEAD
+your current branch changes
+=======
+incoming branch changes
+>>>>>>> conflict-branch
+```
+*Decide which changes to keep, remove the conflict markers, and save the file.*
+
+### Step 6: Stage and Commit Changes
+
+After resolving conflicts, stage the file:
+```bash
+git add example.md
+```
+Commit the resolution:
+```bash
+git commit -m "Resolved merge conflict in example.md"
+```
+
+### Step 7: Push Your Changes
+
+Push the updated branch to your fork:
+```bash
+git push origin <conflict-branch-name>
+```
+
+### Step 8: Open a Pull Request
+
+1. Go to your fork on GitHub → Compare & Pull Request
+
+2. Reference the original issue in the PR description:
+```bash
+Closes #<issue-number>
+```
+3. Submit the PR. Maintainers will review your changes and provide feedback if needed.
+
+## Tips: 
+* Conflicts are normal; everyone faces them. 
+* If the terminal seems hard to use, try GitHub Desktop or the VS Code Git extension. 
+* Always check your changes with git status and git diff before you commit. 
+* Keep your commit messages clear and descriptive.
