+# Downloads Auto-Uploader
+
+Watches your `~/Downloads` folder and automatically syncs new or changed files to a remote server over SSH/rsync. Runs every 5 minutes as a macOS launchd agent.
+
+## How it works
+
+1. SSHes into the remote host and indexes the destination directory (`find` with sizes)
+2. Walks the local scan directory and compares files by size
+3. Uploads only what is missing or has a different size, preserving directory structure
+4. Logs every action to `uploader_log.txt` and records successful uploads in `.uploader_state.json`
+
+Files are skipped if they:
+- Match a skip pattern (hidden files, `.crdownload`, `.part`, `.tmp`, etc.)
+- Were modified less than 30 seconds ago (still being written)
+- Already exist on the remote with the same size
+
+## Requirements
+
+- macOS (uses launchd)
+- `python3` (built-in on macOS, or `brew install python`)
+- `rsync` (`brew install rsync` recommended — macOS ships an outdated version)
+- SSH key-based access to the remote host (no password prompts)
+
+## Quick start
+
+See [INSTALL.md](INSTALL.md).
+
+## Configuration
+
+Edit `downloads_uploader_config.json`:
+
+| Key | Default | Description |
+|-----|---------|-------------|
+| `remote_destination` | `filez@10.10.8.1:/mnt/ssd2t/shared/torrent/Downloads/` | `user@host:/path` on the remote |
+| `ssh_key_path` | `""` | Path to SSH private key; empty = system default (`~/.ssh/id_rsa`) |
+| `ssh_port` | `22` | SSH port |
+| `scan_directory` | `""` | Directory to watch; empty = parent of `uploader/` folder |
+| `skip_patterns` | see config | Shell glob patterns for files/dirs to ignore |
+| `min_file_age_seconds` | `30` | Skip files newer than this (still being downloaded) |
+| `timeout_seconds` | `7200` | Per-file rsync timeout (2 hours) |
+| `remote_scan_timeout` | `120` | Timeout for the remote `find` command |
+| `dry_run` | `false` | Log what would be uploaded without transferring anything |
+
+## Files
+
+```
+uploader/
+  downloads_uploader.py           # main sync script
+  downloads_uploader_install.sh   # launchd installer
+  downloads_uploader_config.json  # configuration
+  .uploader_state.json            # upload audit log (auto-created)
+  uploader_log.txt                # application log (auto-created)
+  uploader_stdout.log             # launchd stdout (auto-created)
+  uploader_stderr.log             # launchd stderr (auto-created)
+```
+
+## Manual usage
+
+```bash
+# Run once right now
+./downloads_uploader_install.sh run
+
+# Dry run (no transfers)
+# Set "dry_run": true in config, then:
+./downloads_uploader_install.sh run
+
+# Check agent status + recent log
+./downloads_uploader_install.sh status
+```
