+## Troubleshooting
+
+### Script not found
+Make sure you're running scripts from the project root directory:
+```bash
+cd explorer-monorepo
+./scripts/run-dev.sh
+```
+
+### Permission denied
+Make scripts executable:
+```bash
+chmod +x scripts/*.sh
+```
+
+### Script fails with path errors
+The scripts automatically detect the project root, but if you encounter issues, make sure you're in the `explorer-monorepo` directory when running them.
