+* Bruno
+Bruno is used for testing the backend API endpoints. It is a simple HTTP client that allows you to send requests to the backend and view the responses. I used the OpenAPI specification to generate Bruno tests for each endpoint.
+
+* Future?
+** Integration with ~notes.zainezq.com~
+As the API is primarily used by ~zainezq.com~, I want to think of ways that ~notes.zainezq.com~ could also use it. This website is used to store all my notes, and they are exported using ~org-publish~ in Emacs. Perhaps I could write an Emacs Lisp package that interacts with the backend API to store and retrieve notes.
+
+Flow of how a note would be written:
+1. User writes a note in ~notes.zainezq.com~ as org mode.
+2. When the note is saved, a POST request is sent to the backend API with the note content.
+3. The backend API stores the note in the database.
+4. This will trigger a function that republishes the notes website to include the new note.
+
+**Need to think more about this.**
