 If you want to cooperate with me, or build something new with my backend API, feel free to reach out!
 
@@ -6,197 +6,145 @@ On this page you will learn how my API works.
 
 ## General information
 
-When you look at my backend folder and file structure, you can see that I have two files called `API`. The first file called `api.js` which is for my web frontend, because this file works together with my JWT token service.
+When you look at my backend folder and file structure, you can see that I have two files called `API`. The first file called `api.js` is for my web frontend, because this file works together with my JWT token service.
 
 But I have built a second API. You can see the second API file in the same directory, the file is called `apiV2.js`.
 
-But first you have to get an API Key. You can get the API key from my admin dashboard. When you don't have any access to my admin dashboard, please contact your administrator or me.
+This is the file that you can use to build an API.
 
----
+But first you have to get the Admin API key, stored in an `.env` file on my server.

-## Base URL
-
-- Frontend: `https://insta.the1s.de`
-- Backend: `https://backend.insta.the1s.de`
-- Base path for this API: `https://backend.insta.the1s.de/apiV2`
-
-You can see the status of this and all my other services at `https://status.the1s.de`.
-
-_I have also build a [fallback page](https://git.the1s.de/theis.gaedigk/fallback-page). When only the application is down, you will see a friendly message and a link to the status page. (Only if the server is not down)_

 ## Authentication
 
-All endpoints require an API key as a path parameter named `:key`.
+All endpoints require the Admin API key (`ADMIN_ID`) as a URL parameter.
 
-Example: `/apiV2/items/:key`
+Example: `/apiV2/items/{ADMIN_ID}`
-
-If the key is missing or invalid, the API responds with `401 Unauthorized`.

-# React + TypeScript + Vite
-
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
-
-Currently, two official plugins are available:
-
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) for Fast Refresh
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
-
-## Expanding the ESLint configuration
-
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
-
-```js
-export default tseslint.config([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-
-      // Remove tseslint.configs.recommended and replace with this
-      ...tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      ...tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules
-      ...tseslint.configs.stylisticTypeChecked,
-
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
-```
-
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
-
-```js
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'
-
-export default tseslint.config([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-      // Enable lint rules for React
-      reactX.configs['recommended-typescript'],
-      // Enable lint rules for React DOM
-      reactDom.configs.recommended,
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
