 2. Use `docker-compose up` to spin up the containers.
 
 You should be able to access the backend through port `3040`
+
+# Methods
+
+For now, we cheat and add a `userId` header which if os type `UUID`. Use the auto generated test one (fcc22dbb-7792-4595-be8e-d0439e13990a).
+
+- `GET /image` | Returns all of the users image, including tags, links and text any image contains.
+- `GET /image/{imageId}` | Returns the actual image, use this to display images in the UI.
+- `POST /image/{imageNameWithExtension}` | Sends an image to the backend, saves it and sents it to open ai to later process.
+
+# Architecture
+
+1. The user posts an image, which gets saved on our database (all data, including images are saved on DB).
+2. We listen for table event creation, and we can process this image by sending it to OpenAI.
+3. After OpenAI responds, we write to the database.
+
+This means that for now, we don't have a notification system to tell the user when their image is done processing. But will do in the future.
