+## How Does It Work?
 
-Basically, Squeak Inbox Talk is implemented by reusing and assembling together the following existing solutions: [Squeak History](https://github.com/hpi-swa/squeak-history), a project originally developed by Marcel (mt) that scrapes and processes all mailing list conversations from the [mailman archives](https://lists.squeakfoundation.org/archives/); the `SMTPClient` in Squeak for sending messages; and the Monticello infrastructure, which remains the heart of our development workflow. Optionally, further components such as [`IMAPClient`](https://github.com/hpi-swa-teaching/IMAPClient) might follow later. On top of this, Squeak Inbox Talk adds a convenient layer for exploring and filtering conversations and contributions.

+## Semantics Plugin (Experimental)
 
 This repository includes an optional plugin that enhances the browsing experience by contributing features such as semantic search, similar conversations, and AI-generated summaries of conversations to Squeak Inbox Talk.
-The plugin uses the [SemanticText](https://github.com/LinqLover/squeak-chatgpt) package and OpenAI's APIs for text embedding and generation.
