+paste has a simple HTTP API which can be used to read and write pastes programmatically.
+
+> [!IMPORTANT]
+> If you are using the official instance of paste (https://pastes.dev), please note the following:
+> 
+> * You must **provide a  `User-Agent` header** to uniquely identify your application in all requests. This should include the application name and contact information, e.g. `ExampleApp (github.com/ExampleUser/ExampleApp)` or `MyExampleScript (github.com/ExampleUser)`.
+> * You must **only upload content when prompted by a user action**, e.g. a button click or command line input. Automated or scheduled uploads are not allowed.
+> * An additional **terms of service** applies. In summary:
+>   * No Illegal Use *(no illegal, harmful or unlawful content)*
+>   * No Malicious Content *(no malware, phishing, personal data without consent, etc.)*
+>   * Content Responsibility *(you are responsible for what you post)*
+>   * Moderation *(we reserve the right to remove content or block access)*
+>   * No Liability *(the service is provided "as is" without warranties)*
+>
+> Otherwise, please enjoy using the service! :)
+
+### Base URL
+The base URL for the 'official' paste instance is: `https://api.pastes.dev/`.
+
+If you are self-hosting, use the base URL of your own instance. With the default Docker Compose setup, this will be `http://localhost:8080/data/`.
+
+## Upload: `POST {BASE URL}/post`
+
+To upload content, send an HTTP `POST` request to `{BASE URL}/post`.
+
+* Include the content in the request body.
+* Specify the language with the `Content-Type: text/<language>` header
+* If using the official instance, please remember to provide a suitable `User-Agent` header as well. (see above for more details)
+* The paste "key" is returned in the `Location` header, and in the response body as a JSON object in the format `{"key": "<key>"}`.**
+
+## Read: `GET {BASE URL}/{key}`
+
+To read content, send an HTTP `GET` request to `{BASE URL}/{key}`.
+
+* Replace `{key}` with the id of the paste.
+* The content is returned in the response body.
+* The `Content-Type` header is `text/<language>`, where language is the id of the language the paste was saved with.

 The user-interface is based on the [Monaco Editor](https://microsoft.github.io/monaco-editor/), the engine behind the popular Visual Studio Code text editor. It's quite simple; it supports syntax highlighting, automatic indentation, many supported languages, themes, zooming in/out, linking to specific lines or sections, and more!

-### Host your own
+### Self-hosting

-It's quite simple to host your own version.
+The easiest way to self-host is using Docker (& Docker Compose). You can run the following commands to get started:

 ```bash
 git clone https://github.com/lucko/paste
 cd paste
-yarn install
-
-# Outputs html/css/js files to /build
-yarn build
-
-# Start a webserver for testing/development
-yarn start
-```
-
-You can then follow the [create-react-app deployment documentation](https://create-react-app.dev/docs/deployment/) for how to host the build output. I personally recommend deploying to the cloud using a service like Netlify instead of hosting on your own webserver.
-
-If you really want to self-host (including the bytebin data storage part), I suggest using Docker:
-
-```bash
-git clone https://github.com/lucko/paste
 docker compose up -d
 ```
