+# Patreon Downloader
+
+Lightweight helpers for using `yt-dlp` to download media from Patreon posts you have access to.
+
+## Contents
+- `with_ui.py` + `frontend.html` — browser-based UI for inspecting post metadata and streaming downloads.
+- `batch.py` — command-line batch downloader (supports `urls.json`).
+- `urls.sample.json` — example JSON input file.
+
+## Features
+- Inspect available formats and metadata before downloading.
+- Stream `yt-dlp` output to the browser with live progress.
+- Batch-mode support for many posts via a JSON file or inline list.
+
+## Requirements
+- Python 3.8+ and `pip`.
+- `yt-dlp` installed and available on PATH (or configure via environment variables).
+
+## Installation
+1. Clone the repository:
+
+```bash
+git clone <repo-url>
+cd patreon-downloader
+```
+
+2. Install dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+3. Export your Patreon cookies to `cookies.txt` (use a browser extension such as “Get cookies.txt”) and place it in the project root.
+
+## Quick Start
+
+### Web UI (recommended)
+1. Start the UI server:
+
+```bash
+python with_ui.py
+```
+
+2. Open http://localhost:5000 in your browser.
+3. Fill in the post URL and the path to `cookies.txt`. Inspect formats and click download. The terminal-like pane shows `yt-dlp` output live.
+
+### Batch mode
+You can provide URLs in two ways:
+
+- Inline in `batch.py`: edit the `URLS` list.
+- JSON file: create `urls.json` (or set `URLS_JSON`) containing an array of URLs.
+
+Example `urls.json` format (see `urls.sample.json`):
+
+```json
+["https://www.patreon.com/posts/example-post-12345678", "https://www.patreon.com/posts/another-example-87654321"]
+```
+
+Run the batch script:
+
+```bash
+python batch.py
+```
+
+## Configuration
+- `YTDLP_PATH` (env): override `yt-dlp` executable for the UI server.
+- `DOWNLOAD_DIR` (env): override download directory used by the UI server.
+- `URLS_JSON` (env): path to a JSON file containing an array of URLs for `batch.py` (default: `./urls.json`).
+
+## JSON input behavior (batch)
+- If `URLS_JSON` exists and contains a non-empty array of strings, `batch.py` will use those URLs.
+- If not present, `batch.py` falls back to the `URLS` list embedded in the script.
+
+## Examples
+- Run single download quickly via UI.
+- Use `urls.sample.json` as a template for bulk downloads.
+
+## Troubleshooting
+- `yt-dlp` extractor or permission errors: re-export `cookies.txt` and ensure they are up to date.
+- UI fetch timeout: the UI uses a 30s timeout for `--dump-json`; run the `yt-dlp --dump-json` command manually to debug.
+- If downloads fail on Windows, ensure `YTDLP` in `batch.py` points to `yt-dlp.exe`.
+
+## Security & Ethics
+- Use this tool only for content you are authorized to access (e.g., from subscriptions you paid for). Respect creators' terms.
+
+## Contributing
+- Bug reports and pull requests welcome. Keep changes minimal and focused.
+
+## Files of interest
+- `with_ui.py` — Flask UI server and job manager.
+- `frontend.html` — browser interface.
+- `batch.py` — command-line batch downloader (now supports JSON input).
+- `urls.sample.json` — example JSON file.
+- `requirements.txt` — Python dependencies.
+
+## License
+- MIT No Attribution — see `MIT-0.txt`.
