+4. Submit the issue
+5. **Save the issue number** (e.g., #12345)
+6. Update `PR_DESCRIPTION.md` to replace the placeholder with: `Addresses #[issue-number]`
+7. Commit the update: `git commit -am "Add issue number to PR description"`
+
+See `CREATE_ISSUE_INSTRUCTIONS.md` for detailed steps.
+
+### Step 2: Push Branch to Fork
+
+```bash
+git push origin preinstall-enhancements
+```
+
+### Step 3: Create PR on GitHub
