   This will let you update the commit message or include additional changes in a single commit.
 
+  To consolidate your existing commits into a single PR, first, you need to reset your branch to the point where you want the single commit to start from (likely the last commit on origin/main before your work began).
+
+  ```bash
+    git reset --soft <commit-id>
+  ```
+
+  Replace `<commit-id>` with the hash of the commit that should be the base of your PR (it is likely the last commit on origin/main before your changes, use that ID).
+
+  Now, all your work will be staged as if it’s a single set of changes. You can commit this with a new message that represents the combined work.
+
+```bash
+git commit -m "Combined changes"
+```
+
+Finally, you can push your changes to your fork with the following command:
+
+```bash
+git push --force origin <feature_branch_name>
