-# [Assignment Name]
+# Implement "Add transaction" dialog
 
 ## Instructions
 
+Our bank app is still missing one important feature: the possibility to enter new transactions.
+Using everything that you've learnt in the four previous lessons, implement an "Add transaction" dialog:
+
+- Add an "Add transaction" button in the dashboard page
+- Either create a new page with an HTML template, or use JavaScript to show/hide the dialog HTML without leaving the dashboard page (you can use [`hidden`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/hidden) property for that, or CSS classes)
+- Implement an HTML form to receive input data
+- Create JSON data from the form data and send it to the API
+- Update the dashboard page with the new data
+
+Look at the [server API specifications](../api/README.md) to see which API you need to call and what is the expected JSON format.
+
+Here's an example result after completing the assignment:
