+# Linux Setup Guide (Debian/Ubuntu/Mint)
+
+Complete instructions for setting up LBRY Downloader on Debian-based Linux distributions.
+
+## Quick Start (Automated Setup)
+
+The easiest way to install is using the interactive setup script:
+
+```bash
+# Clone the repository
+git clone https://github.com/yourusername/LBRY-Downloader.git
+cd LBRY-Downloader
+
+# Run the interactive installer
+./setup.py
+```
+
+This script will:
+1. Check and install system dependencies
+2. Set up a Python virtual environment
+3. Install Python packages
+4. Ask for your download location
+5. Configure channels to download from
+6. Set download limits
+7. Create launcher scripts
+
+**Want to uninstall later?** Just run `./uninstall.py`
+
+---
+
+## Manual Installation
+
+If you prefer to set things up manually, follow the steps below.
+
+## Prerequisites
+
+### 1. System Packages
+
+```bash
+# Update system
+sudo apt update && sudo apt upgrade -y
+
+# Install Python and required system packages
+sudo apt install -y \
+    python3 \
+    python3-pip \
+    python3-venv \
+    git \
+    curl \
+    wget
+
+# Verify Python installation
+python3 --version  # Should be 3.8 or higher
+pip3 --version
+```
+
+### 2. Install LBRY SDK (lbrynet daemon)
+
+The LBRY SDK is required to communicate with the LBRY network.
+
+#### Option A: Download Pre-built Binary (Recommended)
+
+```bash
+# Create directory for lbrynet
+mkdir -p ~/.local/bin
+cd ~/.local/bin
+
+# Download latest release (check https://github.com/lbryio/lbry-sdk/releases for latest)
+# For x86_64 systems:
+LBRY_VERSION="0.113.0"  # Check for latest version
+wget "https://github.com/lbryio/lbry-sdk/releases/download/v${LBRY_VERSION}/lbry-sdk-linux.zip"
+
+# Extract
+unzip lbry-sdk-linux.zip
+rm lbry-sdk-linux.zip
+
+# Make executable
+chmod +x lbrynet
+
+# Add to PATH if not already there
+if ! echo $PATH | grep -q "$HOME/.local/bin"; then
+    echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
+    source ~/.bashrc
+fi
+
+# Verify installation
+lbrynet --version
+```
+
+#### Option B: Build from Source (Advanced)
+
+```bash
+# Install build dependencies
+sudo apt install -y \
+    build-essential \
+    libssl-dev \
+    libffi-dev \
+    python3-dev \
+    python3-venv
+
+# Clone and build (not recommended for most users)
+git clone https://github.com/lbryio/lbry-sdk.git
+cd lbry-sdk
+python3 -m venv venv
+source venv/bin/activate
+pip install -e .
+```
+
+## Installation
+
+### 1. Clone the Repository
+
+```bash
+# Navigate to where you want to install
+cd ~/Documents  # or wherever you prefer
+
+# Clone (if you have git access) or extract the zip
+git clone https://github.com/yourusername/LBRY-Downloader.git
+# OR if you downloaded a zip:
+# unzip LBRY-Downloader.zip -d LBRY-Downloader
+
+cd LBRY-Downloader
+```
+
+### 2. Set Up Python Environment
+
+```bash
+# Option A: Using system Python (simpler)
+pip3 install --user -r requirements.txt
+
+# Option B: Using virtual environment (recommended for developers)
+python3 -m venv venv
+source venv/bin/activate
+pip install -r requirements.txt
+```
+
+### 3. Verify Installation
+
+```bash
+# Test Python imports
+python3 -c "from main import run_sync; print('✓ Imports OK')"
+
+# Test CLI
+python3 main.py --help
+```
+
+## Configuration
+
+### 1. Initialize Configuration
+
+```bash
+# Run initialization script
+python3 init.py
+
+# This creates:
+# ~/Documents/lbry-downloads/config.yaml
+# ~/Documents/lbry-downloads/state/
+# ~/Documents/lbry-downloads/channels/
+```
+
+### 2. Edit Configuration
+
+```bash
+# Open config in your preferred editor
+nano ~/Documents/lbry-downloads/config.yaml
+# OR
+gedit ~/Documents/lbry-downloads/config.yaml
+# OR
+vim ~/Documents/lbry-downloads/config.yaml
+```
+
+### 3. Add Your Channels
+
+Edit the `channels:` section:
+
+```yaml
+channels:
+  - input: "https://odysee.com/@SomeChannel:1"
+    enabled: true
+    tags_include: []
+    tags_exclude: []
+  
+  - input: "lbry://@AnotherChannel#5"
+    enabled: true
+    tags_include: []
+    tags_exclude: []
+```
+
+**Finding Channel URLs:**
+- Go to Odysee.com and navigate to a channel
+- Copy the URL from your browser
+- Paste it into the config
+
+### 4. Configure Per-Channel Download Locations (Optional)
+
+By default, all downloads go to `~/Documents/lbry-downloads/channels/`. You can specify custom locations for each channel:
+
+```yaml
+channels:
+  # Downloads to default location
+  - input: "https://odysee.com/@RegularChannel:1"
+    enabled: true
+  
+  # Downloads to custom location (external drive)
+  - input: "https://odysee.com/@LargeVideos:1"
+    enabled: true
+    download_path: "/mnt/media/videos"
+  
+  # Downloads to custom location (home directory)
+  - input: "https://odysee.com/@Music:1"
+    enabled: true
+    download_path: "~/Music/LBRY"
+```
+
+**Why use custom locations?**
+- Store large channels on external drives
+- Organize content by type (videos, music, etc.)
+- Manage disk space across multiple drives
+- Keep important channels on fast SSD, archive on slow HDD
+
+**Note:** Make sure the custom path exists and you have write permissions:
+```bash
+mkdir -p /mnt/media/videos
+# Check permissions
+ls -la /mnt/media/
+```
+
+### 5. Configure Download Limits (Optional)
+
+Limit how many new items to download per channel. This is especially useful for:
+- **Testing** - Download just a few files first
+- **Large channels** - Channels with thousands of videos
+- **Bandwidth control** - Limit data usage per run
+
+```yaml
+general:
+  # Default: download 10 most recent items per channel
+  download_limit: 10
+  
+  # To download everything (use with caution!):
+  # download_limit: 0
+  
+  # For testing, download only 2-3 items:
+  # download_limit: 3
+```
+
+The tool downloads **most recent items first** (sorted by publish date), so:
+- `download_limit: 10` = Download the 10 newest videos
+- Older items remain in the channel but won't be downloaded yet
+- On next run, it will download the next 10 (if new items were published)
+
+**Recommended approach for large channels:**
+```yaml
+general:
+  download_limit: 10  # Start with a small number
+
+channels:
+  - input: "https://odysee.com/@HugeArchive:1"
+    enabled: true
+    # Downloads only 10 most recent to test
+```
+
+Once you're happy with how it works, increase the limit or set to 0.
+
+## Running the Daemon
+
+The LBRY daemon (`lbrynet`) must be running before using the downloader.
+
+### Start the Daemon
+
+```bash
+# Start lbrynet
+lbrynet start
+
+# Check status
+lbrynet status
+
+# You should see JSON output with daemon information
+```
+
+### Running as a Systemd Service (Optional)
+
+Create a systemd service to auto-start lbrynet:
+
+```bash
+# Create service file
+sudo tee /etc/systemd/system/lbrynet.service > /dev/null <<EOF
+[Unit]
+Description=LBRY SDK Daemon
+After=network.target
+
+[Service]
+Type=simple
+User=$USER
+ExecStart=$HOME/.local/bin/lbrynet start
+Restart=on-failure
+RestartSec=10
+
+[Install]
+WantedBy=multi-user.target
+EOF
+
+# Reload systemd
+sudo systemctl daemon-reload
+
+# Enable and start service
+sudo systemctl enable lbrynet
+sudo systemctl start lbrynet
+
+# Check status
+sudo systemctl status lbrynet
+
+# View logs
+sudo journalctl -u lbrynet -f
+```
+
+### Stop the Daemon
+
+```bash
+# If running manually
+lbrynet stop
+
+# If running as systemd service
+sudo systemctl stop lbrynet
+```
+
+## Using the Downloader
+
+### First Run (Dry Run)
+
+Always test with dry-run first:
+
+```bash
+cd ~/Documents/LBRY-Downloader  # or wherever you installed it
+
+python3 main.py --dry-run
+```
+
+This shows what would be downloaded without actually downloading anything.
+
+### Normal Run
+
+```bash
+# Make sure lbrynet is running
+lbrynet status
+
+# Run the downloader
+python3 main.py
+```
+
+### Custom Config Location
+
+```bash
+python3 main.py --config /path/to/custom/config.yaml
+```
+
+### Viewing Progress
+
+The tool outputs progress to the console:
+
+```

+```
+
+## Automation (Optional)
+
+### Create a Wrapper Script
+
+```bash
+# Create convenient wrapper
+tee ~/bin/lbry-sync > /dev/null <<'EOF'
+#!/bin/bash
+cd ~/Documents/LBRY-Downloader
+source venv/bin/activate 2>/dev/null || true
+
+# Check if lbrynet is running
+if ! curl -s http://127.0.0.1:5279 > /dev/null 2>&1; then
+    echo "Starting lbrynet daemon..."
+    lbrynet start &
+    sleep 5
+fi
+
+# Run downloader
+python3 main.py "$@"
+EOF
+
+chmod +x ~/bin/lbry-sync
+
+# Now you can just run:
+# lbry-sync
+# lbry-sync --dry-run
+```
+
+### Cron Job for Regular Syncs
+
+```bash
+# Edit crontab
+crontab -e
+
+# Add line to run daily at 3 AM:
+0 3 * * * cd ~/Documents/LBRY-Downloader && python3 main.py >> ~/lbry-sync.log 2>&1
+
+# Or weekly on Sundays at 2 AM:
+0 2 * * 0 cd ~/Documents/LBRY-Downloader && python3 main.py >> ~/lbry-sync.log 2>&1
+```
+
+## Troubleshooting
+
+### "Could not connect to LBRY daemon"
+
+```bash
+# Check if lbrynet is running
+lbrynet status
+
+# If not running, start it
+lbrynet start
+
+# Check if it's listening on the expected port
+netstat -tlnp | grep 5279
+# OR
+ss -tlnp | grep 5279
+
+# Check daemon logs (if running as systemd)
+sudo journalctl -u lbrynet -n 50
+```
+
+### "Permission denied" when running lbrynet
+
+```bash
+# Ensure lbrynet is executable
+chmod +x ~/.local/bin/lbrynet
+
+# Check PATH
+echo $PATH
+# Should include /home/YOURUSERNAME/.local/bin
+```
+
+### "ModuleNotFoundError" for Python packages
+
+```bash
+# Reinstall dependencies
+cd ~/Documents/LBRY-Downloader
+
+# If using system Python:
+pip3 install --user --force-reinstall -r requirements.txt
+
+# If using venv:
+source venv/bin/activate
+pip install --force-reinstall -r requirements.txt
+```
+
+### "Config file not found"
+
+```bash
+# Run initialization again
+python3 init.py
+
+# Or manually create the directory
+mkdir -p ~/Documents/lbry-downloads/state
+mkdir -p ~/Documents/lbry-downloads/channels
+
+# And create a config file from the example
+cp config.yaml.example ~/Documents/lbry-downloads/config.yaml
+```
+
+### Downloads are slow
+
+LBRY downloads can be slow depending on network conditions. This is normal:
+
+```yaml
+# In config.yaml, reduce max_workers if needed
+general:
+  max_workers: 1  # Download one at a time
+  timeout_seconds: 300  # Increase timeout
+```
+
+### Disk space issues
+
+Check the download directory size:
+
+```bash
+du -sh ~/Documents/lbry-downloads/channels/
+du -sh ~/Documents/lbry-downloads/channels/* | sort -hr | head -20
+```
+
+## Updating
+
+### Update the Downloader
+
+```bash
+cd ~/Documents/LBRY-Downloader
+
+# If using git:
+git pull
+
+# If manual download, re-download and replace files
+
+# Update Python dependencies
+pip3 install --user --upgrade -r requirements.txt
+# OR if using venv:
+source venv/bin/activate
+pip install --upgrade -r requirements.txt
+```
+
+### Update lbrynet
+
+```bash
+# Stop current daemon
+lbrynet stop
+
+# Download new version (see installation section)
+cd ~/.local/bin
+# ... download and extract new version ...
+
+# Restart
+lbrynet start
+```
+
+## Uninstallation
+
+```bash
+# Stop daemon
+lbrynet stop
+
+# Remove downloader
+rm -rf ~/Documents/LBRY-Downloader
+rm -rf ~/Documents/lbry-downloads

+1. Check the logs: `~/Documents/lbry-downloads/state/run-history.jsonl`
+2. Run with debug logging: Set `log_level: "DEBUG"` in config.yaml
+3. Test daemon connectivity:
+   ```bash
+   curl -X POST http://127.0.0.1:5279 \
+     -H "Content-Type: application/json" \
+     -d '{"jsonrpc":"2.0","method":"status","params":{},"id":1}'
+   ```
+
+## Uninstallation
+
+To remove LBRY Downloader:
+
+```bash
+# Run the uninstall script
+./uninstall.py
+```
+
+This will:
+- Find your installation and download directories
+- Ask for confirmation before removing
+- Show you what's being deleted
+- Optionally help clean up PATH entries
+
+**Manual uninstall:**
+
+```bash
+# Stop the daemon
+lbrynet stop
+
+# Remove installation directory
+rm -rf ~/Documents/LBRY-Downloader
+
+# Remove downloads (optional - backup first!)
+rm -rf ~/Documents/lbry-downloads
+
+# Remove lbrynet (optional)
+rm ~/.local/bin/lbrynet
+
+# Remove from PATH if you added it
+# Edit ~/.bashrc and remove the lbry-downloader PATH line
+```

+## Features Implemented
+
+### Core Functionality
+✅ Channel resolution (Odysee URL, LBRY URI, claim ID)
+✅ Incremental sync (only new/changed content)
+✅ Version tracking (sd_hash, stream_hash, txid fallback)
+✅ Atomic state writes (prevents corruption)
+✅ Run history logging (JSONL format)
+✅ Dry-run mode (test without downloading)
+✅ Configurable YAML configuration
+✅ Comprehensive logging
+✅ Error handling and recovery
+
+### Download Management
+✅ Structured folder layout (channel/claim/version)
+✅ **Per-channel download paths** - Custom location per channel
+✅ Metadata preservation (metadata.json, download.json)
+✅ Checksum generation (SHA256)
+✅ File verification
+✅ Missing file redownload
+✅ Repost filtering (optional)
+
+### Quality & Testing
+✅ 42 unit tests (all passing)
+✅ Type hints throughout
+✅ Clear error messages
+✅ Input validation
+✅ Path sanitization
+✅ Atomic operations
+
+---
+
+## Architecture Highlights
+
+### Design Principles
+- **Daemon-first**: Uses local lbrynet, not HTML scraping
+- **Identity-stable**: claim_id + sd_hash, not titles/names
+- **Version-preserving**: Keeps old versions, doesn't overwrite
+- **State-driven**: Persistent database for incremental sync
+- **Atomic writes**: State updates are crash-safe

+# LBRY Downloader
+
+A Python tool that incrementally syncs downloadable file claims from configured LBRY/Odysee channels into a structured local archive.
+
+## Features
+
+- **Incremental Sync**: Only downloads new claims and updated versions
+- **Version Preservation**: Keeps old versions instead of overwriting them
+- **Robust Identity**: Uses stable LBRY claim IDs, not display names or titles
+- **Atomic State**: Database writes are atomic to prevent corruption
+- **Daemon-Based**: Talks directly to local `lbrynet` daemon via JSON-RPC
+- **Flexible Input**: Accepts Odysee URLs, LBRY URIs, or claim IDs
+- **Audit Trail**: Maintains run history in JSONL format
+- **Dry-Run Mode**: Test what would happen without downloading
+
+## Installation
+
+### Easy Install (Recommended)
+
+Run the interactive setup script that handles everything:
+
+```bash
+# Clone the repository
+git clone https://github.com/yourusername/LBRY-Downloader.git
+cd LBRY-Downloader
+
+# Run the interactive installer
+./setup.py
+```
+
+The setup script will:
+- ✅ Check and install system dependencies
+- ✅ Set up a Python virtual environment
+- ✅ Install Python packages
+- ✅ Ask for your download location
+- ✅ Configure channels to download from
+- ✅ Set download limits
+- ✅ Create launcher scripts
+
+### Manual Install
+
+See [LINUX_SETUP.md](LINUX_SETUP.md) for detailed manual installation instructions.
+
+### Uninstall
+
+To remove LBRY Downloader:
+
+```bash
+./uninstall.py
+```
+
+## Prerequisites
+
+You need to have the LBRY SDK daemon (`lbrynet`) installed and running:
+
+```bash
+# The daemon should be accessible at http://127.0.0.1:5279
+# Check if it's running:
+curl -X POST http://127.0.0.1:5279 \
+  -H "Content-Type: application/json" \
+  -d '{"jsonrpc":"2.0","method":"status","params":{},"id":1}'
+```
+
+To install `lbrynet`, see: https://lbry.com/get
+
+## Configuration
+
+Copy the example config and edit it:
+
+```bash
+cp config.yaml.example ~/Documents/lbry-downloads/config.yaml
+# Edit the file to add your channels
+```
+
+Example configuration:
+
+```yaml
+lbrynet:
+  api_url: "http://127.0.0.1:5279"
+  timeout_seconds: 60
+
+general:
+  base_dir: "~/Documents/lbry-downloads"
+  max_workers: 2
+  dry_run: false
+  include_reposts: false
+
+channels:
+  - input: "https://odysee.com/@SomeChannel:1"
+    enabled: true
+  - input: "lbry://@AnotherChannel#5"
+    enabled: true
+```
+
+### Per-Channel Download Locations
+
+You can specify a custom download location for each channel:
+
+```yaml
+channels:
+  - input: "https://odysee.com/@TechVideos:1"
+    enabled: true
+    download_path: "/mnt/media/tech"  # Downloads go here instead of base_dir
+  
+  - input: "https://odysee.com/@Music:1"
+    enabled: true
+    download_path: "~/Music/LBRY"
+  
+  - input: "https://odysee.com/@DefaultLocation:1"
+    enabled: true
+    # No download_path - uses general.base_dir/channels/
+```
+
+### Download Limit
+
+Limit how many new downloads per channel (downloads most recent first):
+
+```yaml
+general:
+  # Download only 10 most recent items per channel (default)
+  download_limit: 10
+  
+  # Or set to 0 to download everything
+  # download_limit: 0
+```
+
+This is useful for:
+- **Testing**: Download just a few files to verify everything works
+- **Large channels**: Gradually sync channels with thousands of videos
+- **Bandwidth**: Control how much data is downloaded per run
+
+## Usage
+
+```bash
+# Run with default config
+python main.py
+
+# Use custom config
+python main.py --config ./my-config.yaml
+
+# Dry run - see what would happen
+python main.py --dry-run
+```
+
+## Directory Structure
+
+Downloads are organized as:
+
+```
+~/Documents/lbry-downloads/
+  config.yaml
+  state/
+    database.json
+    run-history.jsonl
+  channels/
+    <channel_name>__<channel_claim_id>/
+      channel.json
+      claims/
+        <claim_name>__<claim_id>/
+          claim.json
+          versions/
+            <version_token>/
+              <downloaded_file>
+              metadata.json
+              download.json
+              checksums.txt
+```
+
+## How It Works
+
+1. **Channel Resolution**: Converts URLs/URIs to stable channel claim IDs
+2. **Claim Enumeration**: Paginates through all claims in each channel
+3. **Version Detection**: Uses `sd_hash` to detect updated content
+4. **Smart Skipping**: Only downloads new claims or changed versions
+5. **Metadata Preservation**: Stores normalized metadata beside each file
+
+## State Management
+
+The tool maintains state in `state/database.json`:
+- Tracks which channels have been scanned
+- Records claim metadata and version history
+- Prevents duplicate downloads
+- Detects missing files for re-download
+
+## Troubleshooting
+
+### "Could not connect to LBRY daemon"
+Make sure `lbrynet` is running:
+```bash
+lbrynet start
+```
+
+### "Config file not found"
+Create a config at the default location or specify a path:
+```bash
+python main.py --config ./config.yaml
+```
+
+### Dry run shows no downloads
+Check that your channels are enabled and have downloadable content (streams, not just reposts).

+# Per-Channel Download Paths Example
+
+This example shows how to configure different download locations for each channel.
+
+## Use Case: Organize by Content Type
+
+```yaml
+lbrynet:
+  api_url: "http://127.0.0.1:5279"
+
+general:
+  base_dir: "~/Documents/lbry-downloads"
+  max_workers: 2
+
+channels:
+  # Tech videos go to external drive
+  - input: "https://odysee.com/@TechChannel:1"
+    enabled: true
+    download_path: "/mnt/media/videos/tech"
+  
+  # Music goes to Music folder
+  - input: "https://odysee.com/@MusicChannel:1"
+    enabled: true
+    download_path: "~/Music/LBRY"
+  
+  # Podcasts go to Podcasts folder  
+  - input: "https://odysee.com/@PodcastChannel:1"
+    enabled: true
+    download_path: "~/Podcasts"
+  
+  # Everything else goes to default location
+  - input: "https://odysee.com/@MiscChannel:1"
+    enabled: true
+    # No download_path - uses general.base_dir/channels/
+```
+
+## Use Case: Manage Disk Space
+
+```yaml
+channels:
+  # Large archive channel goes to big external drive
+  - input: "https://odysee.com/@Archive:1"
+    enabled: true
+    download_path: "/mnt/8tb-drive/archive"
+  
+  # Frequently accessed channel goes to fast SSD
+  - input: "https://odysee.com/@DailyUpdates:1"
+    enabled: true
+    download_path: "~/Videos/daily"
+```
+
+## Use Case: Separate Personal and Work
+
+```yaml
+channels:
+  # Work-related content
+  - input: "https://odysee.com/@TechTalks:1"
+    enabled: true
+    download_path: "~/Work/Videos"
+  
+  # Personal entertainment
+  - input: "https://odysee.com/@Entertainment:1"
+    enabled: true
+    download_path: "~/Videos/entertainment"
+```
+
+## Setting Up Custom Paths
+
+### 1. Create the directories
+
+```bash
+# External drive example
+sudo mkdir -p /mnt/media/videos/tech
+sudo chown $USER:$USER /mnt/media/videos/tech
+
+# Home directory example
+mkdir -p ~/Music/LBRY
+mkdir -p ~/Podcasts
+```
+
+### 2. Edit config.yaml
+
+```bash
+nano ~/Documents/lbry-downloads/config.yaml
+```
+
+### 3. Test with dry-run
+
+```bash
+python main.py --dry-run
+```
+
+Check the output to see where files would be downloaded.
+
+### 4. Run the download
+
+```bash
+python main.py
+```
+
+## Resulting Directory Structure
+
+With the example above, your files will be organized as:
+
+```
+/mnt/media/videos/tech/
+  TechChannel__abc123/
+    channel.json
+    claims/
+      video1__def456/
+        versions/
+          sd_xyz789/
+            video.mp4
+
+~/Music/LBRY/
+  MusicChannel__ghi789/
+    channel.json
+    claims/
+      song1__jkl012/
+        versions/
+          sd_mno345/
+            song.mp3
+
+~/Podcasts/
+  PodcastChannel__pqr678/
+    ...
+
+~/Documents/lbry-downloads/channels/
+  MiscChannel__stu901/
+    ...
+```
+
+## Tips
+
+1. **Path expansion**: Use `~` for home directory - it will be expanded automatically
+2. **Absolute paths**: Always use absolute paths for external drives
+3. **Permissions**: Ensure you have write permissions to custom paths
+4. **Existing downloads**: If you move a channel's download location after files have been downloaded, the tool will redownload them to the new location
+
+## State Management
+
+The state database still lives in `~/Documents/lbry-downloads/state/` regardless of where you download files. This keeps all metadata and tracking in one place.
