+## Troubleshooting
+
+### Common Installation Issues
+- **Error: `npm install` fails**: 
+  - Ensure that [Node.js](https://nodejs.org/en/download/) and npm are correctly installed on your machine. You can check this by running `node -v` and `npm -v` in your terminal.
+  - If you encounter permission issues, try using `sudo npm install` (for macOS/Linux) or running the command prompt as an administrator (for Windows).
+
+### Problems with Starting the Server
+- **Error: `Cannot find module 'express'`**:
+  - This error usually indicates that the required packages haven't been installed. Make sure to run `npm install` in both the root and `client` directories.
+- **Server crashes on startup**: 
+  - Check the console logs for any errors that may provide hints about what went wrong. Common issues could be related to incorrect environment variables or database connection strings.
+
+### Issues Related to Dependencies
+- **Version conflicts**:
+  - Ensure that all dependencies in your `package.json` are compatible. If you see warnings or errors during installation, consider using `npm audit fix` to resolve vulnerabilities.
+
+### FAQs
+- **Q: How do I reset my local database?**
+  - A: You can drop the existing database and run your migrations or seed scripts again. Make sure to back up any important data before doing this.
+
+- **Q: How can I contact support?**
+  - A: If you have further issues or questions, please open an issue in this repository, and we'll be happy to help!
+
+### Additional Suggestions
+- **Clarity**: Make sure the instructions are as clear as possible. For example, specify where to run commands (in which directory).
+- **Links**: If you refer to any external resources (like Node.js downloads), adding hyperlinks could be beneficial.
