 # KOReaderServerFetcher
 
-A KOReader plugin plus server combo
\ No newline at end of file
+A simple setup to push books from your computer to your e-reader. Hit a button on your Kindle/Kobo, get your books just that easy.
+
+## What This Does
+
+- **Server**: Python HTTP server that serves files from a folder and archives them after sending
+- **Plugin**: KOReader plugin that fetches those files with one tap
+
+## Setup
+
+### Server Side
+
+1. Put `server.py` somewhere on your computer
+
+2. Create a config at the top of the file:
+   - Set `AUTH_TOKEN` to something secret
+   - Set `SOURCE_DIR` to where you drop books (e.g., `/home/you/books/inbox`)
+   - Set `ARCHIVE_DIR` to where served books go (e.g., `/home/you/books/sent`)
+
+3. Run it:
+   ```bash
+   python3 server.py
+   ```
+
+4. (Optional) Make it a service so it starts automatically:
+   ```bash
+   sudo cp file-server.service /etc/systemd/system/
+   # Edit the file to fix paths and username
+   sudo systemctl enable file-server
+   sudo systemctl start file-server
+   ```
+
+### KOReader Plugin
+
+1. Copy the plugin folder to your device:
+   ```
+   koreader/plugins/fetch.koplugin/
+   ├── main.lua
+   └── config.lua
+   ```
+
+2. Edit `config.lua`:
+   ```lua
+   return {
+       server_url = "http://your-server:8000/get",
+       auth_token = "your-secret-token-here"
+   }
+   ```
+
+3. Restart KOReader
+
+## Usage
+
+1. Drop books into your server's inbox folder
+2. On your e-reader: Menu → Fetch Files → Fetch Now
+3. Books appear in your configured directory
+
+First time setup: go to Menu → Fetch Files → Configure Home Directory to pick where books should go.
+
+## How It Works
+
+The server zips up everything in the source folder and sends it over. After sending, it moves those files to the archive folder so you don't get duplicates next time.
+
+The plugin downloads the zip, extracts it, and cleans up after itself.
+
+## Nginx Setup
+
+If you want to access this over the internet, put it behind nginx with SSL:
+
+```nginx
+location /get {
+    proxy_pass http://localhost:8000;
+    proxy_set_header X-Forwarded-For $remote_addr;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header Host $host;
+}
+```
+
+## Troubleshooting
+
+**Plugin doesn't show up**: Check KOReader's crash.log
+
+**Can't connect to server**: Make sure the URL in config.lua is correct and the server is running
+
+**Authentication failed**: Token mismatch between server.py and config.lua
+
+**Files not extracting**: The plugin needs `unzip` available on your device (it usually is)
+
+**Server logs wrong IP**: Make sure nginx is forwarding the X-Forwarded-For header
+
+## Requirements
+
+- Python 3.6+
+- KOReader
+- `unzip` command on your e-reader (standard on most devices)
+
+## License
+
+Do whatever you want with this.
