+
+## Contributing
+
+We'd love to see more examples here. If you have an idea that you'd like to see included here, submit a Pull Request and we'll be sure to review it!  Don't forget to check out our [contributing guide](../CONTRIBUTING.md).
+
+### Coding Guidelines for Examples
+
+When adding a new example, please follow these guidelines:
+
+* Add your code in a single JavaScript file per example, directly in the `examples` folder
+* Do not introduce other dependencies in your example
+* Give your `.js` file a meaningful name using `-` separators e.g. `adding-to-a-stream.js`
+* Indent your code using 2 spaces
+* Use the single line `//` comment style and comment your code
+* Add a comment at the top of your `.js` file describing what your example does
+* Add a comment at the top of your `.js` file describing any Redis commands that need to be run to set up data for your example (try and keep this minimal)
+* Use semicolons
+* Use `async` and `await`
+* Use single quotes, `'hello'` not `"hello"`
+* Place your example code in a single `async` function where possible, named according to the file name e.g. `add-to-stream.js` would contain `const addtoStream = async () => { ... };`, and call this function at the end of the file e.g. `addToStream();`
+* Unless your example requires a connection string, assume Redis is on the default localhost port 6379 with no password
+* Use meaningful example data, let's not use `foo`, `bar`, `baz` etc!
+* Leave on empty line at the end of your `.js` file
+* Update this `README.md` file to add your example to the table
+
+Use [connect-as-acl-user.js](connect-as-acl-user.js) as a guide to develop a well formatted example script.
+
+### Example Template
+
+Here's a starter template for adding a new example, imagine this is stored in `do-something.js`:
+
+```javascript
+// This comment should describe what the example does
+// and can extend to multiple lines.
+
+// Set up the data in redis-cli using these commands:
+//   <add your command(s) here, one per line>
+
+import { createClient } from 'redis';
+
+const doSomething = async () => {
+  const client = createClient();
+
+  await client.connect();
+
+  // Add your example code here...
+
+  await client.quit();
+}
+
+
+doSomething();
+```
