 # nsfwbot for Matrix
 
-`nsfwbot` is a Matrix bot plugin that attempts to detect NSFW (Not Safe For Work) images posted in
-Matrix chat rooms. It uses [nsfwdetection](https://github.com/gsarridis/NSFW-Detection-Pytorch),
-which includes a small model that can run without a GPU with low resource requirements.
+`nsfwbot` is a Matrix bot plugin that detects NSFW (Not Safe For Work) images posted in Matrix chat rooms. It uses [nudenet](https://github.com/notAI-tech/NudeNet), which includes a deep learning model that efficiently runs without requiring a GPU, with low resource demands.
 
 ## Features
 
-- **Image Analysis**: Detects and analyses images posted in Matrix chats.
-- **Text Message Parsing**: Analyses images embedded in text messages.
+- **Image Analysis**: Detects and analyzes images posted in Matrix chats using NudeNet.
+- **Redaction of Spammed Images**: Automatically redacts images when users send more than the allowed number within a short time frame.
+- **Text Message Parsing**: Analyzes images embedded in text messages.
 - **Configurable Concurrency**: Controls concurrent image processing tasks.
 - **Custom Actions**: Configurable actions for detected content, including reporting and redacting messages.
 
 ## Requirements
 
 - **Maubot**: Runs within the Maubot framework.
-- **Python Dependencies**: `nsfwdetection` and `beautifulsoup4`.
-  > **Note**: `nsfwdetection` will not run on Alpine Linux. This means the default Maubot Docker
-  > image will not work. I have built a custom Debian-based Maubot in the
-  > `ghcr.io/tcpipuk/maubot:debian` Docker image.
+- **Python Dependencies**: `nudenet`, `beautifulsoup4`, and `maubot`.
+  
+  > **Note**: The `nudenet` package and other dependencies will not run on Alpine Linux, so use the custom Debian-based Maubot Docker image.
+  
+  To install the dependencies, you can find them listed in the `requirements.txt`:

-## Configuration
+   - `max_concurrent_jobs`: Number of concurrent jobs to allow.
+   - `via_servers`: List of servers for `matrix.to` URLs.
+   - `actions`:
+     - `ignore_sfw`: Ignore SFW images (default: `true`).
+     - `redact_nsfw`: Redact NSFW messages (default: `true`).
+     - `direct_reply`: Reply directly in the same room (default: `false`).
+     - `report_to_room`: Room ID for reporting (optional).
+     - `max_images`: The maximum number of images a user can send within a certain time window (default: `3`).
+     - `time_window`: The time window (in seconds) in which the image count is tracked (default: `60` seconds).

 ## Usage
 
-Once installed and configured, `nsfwbot` will automatically analyse images posted in the chat and
-reply with a classification result, e.g.
+Once installed and configured, `nsfwbot` will automatically analyze images posted in the chat and:
+
+- Classify images as NSFW or SFW.
+- Redact images if a user exceeds the configured spam limit (`max_images`).
+- Optionally report detected NSFW content to a configured room.
