1. Log in to the Xano platform.
2. Head over to the "Database" section on the left-hand menu.
3. Pick the specific database or endpoint you want to create or edit a script for.
4. Hit the "Edit" button to get into the custom script editor.

1. Click the "New Function" button at the top-right corner of the script editor.
2. Give your function a name and description so you can easily find it later.
3. Choose the type of function (Server-Side, Database, etc.) based on what you need.

1. Click on the "Input" tab in the script editor.
2. Add the parameters your function needs and define their data types (String, Integer, Object, etc.).
3. Save those input parameters.

1. Go to the "Script" tab to write your custom logic.
2. Use Xano’s scripting language, which is similar to JavaScript. Here's a quick example:
   ```javascript
   let response = {
   message: "Hello, " + input.user + "!",
   timestamp: Date.now()
   };
   return response;
   ```
3. Use built-in functions if you need to interact with your database or other services.
4. Add comments to your code for future reference and better readability.

1. Click on the "Debug" tab near the script window.
2. Provide some sample input data to test your function.
3. Run the script to see the output and make sure it works as expected.
4. If there are any errors, review the logs in Xano’s debug environment to fix them.

1. Once your script is tested and working, click the "Save" button to save your work.
2. Deploy the function if you plan to use it in a production environment.
3. Integrate the function into workflows, endpoints, or other functional units as needed.

1. Xano lets you manage different versions of your scripts.
2. Click on the "Versions" tab to create a new version or revert to a previous one if necessary.
3. Document changes in each version to keep track of modifications over time.

1. Xano offers shared functions that can be reused across different scripts.
2. Click on the "Shared Functions" tab to define a function that can be called from multiple scripts.
3. Define the shared function and use it within your custom script by calling it appropriately.

By following these steps, you can make the most of Xano’s custom script editor for advanced tasks, enabling powerful and efficient app development.
