 # LetterFeed
 
-LetterFeed is a self-hosted application that converts email newsletters into RSS feeds. Kind of like [kill the newsletter](https://github.com/leafac/kill-the-newsletter/), but with a given inbox.
+LetterFeed is a self-hosted application that transforms your email newsletters into tidy, readable RSS feeds. It connects to your existing email account, finds the newsletters you specify, and generates a unique RSS feed for each one.

+## Features
+
+- **Email to RSS Conversion:** Automatically converts emails from specified senders into a standard RSS feed.
+- **Content Extraction:** Optionally, LetterFeed can extract the main article content from the email body.
+- **Email Management:** Can automatically move processed emails to a specified folder in your inbox to keep things organized.
+- **Easy to Use Interface:** A simple web interface to manage your newsletters and feeds.
+
+## How It Works
+
+LetterFeed periodically scans your email inbox via IMAP for new emails from the senders you've configured. When it finds a new email, it processes it, and adds it as a new entry to the corresponding newsletter's RSS feed.
