- contributing/ - Contribution guides

Changes:
- Created portal INDEX.md files for each audience section
- Moved device guides to user/devices/ (kobo-setup.md, koreader-setup.md)
- Moved API docs to developer/ (api-reference.md, collections-api.md)
- Moved sync guide to user/sync-guide.md
- Moved troubleshooting to operations/troubleshooting.md

### OPDS Troubleshooting
#### Catalog Not Appearing
**Problem**: Bookhoard catalog doesn't show in Kobo store
**Solutions**:
1. Verify OPDS URL is correct in config file
2. Check Kobo is connected to Wi-Fi
3. Try accessing OPDS URL in your browser
4. Ensure device ID matches Bookhoard device ID
5. Restart Kobo after editing config file
#### Download Fails
**Problem**: Book download starts but fails partway through
**Solutions**:
1. Check Wi-Fi signal strength
2. Ensure Bookhoard server is running
3. Verify book file exists in Bookhoard library
4. Try downloading a smaller book first
5. Check Bookhoard logs for errors
#### Book Downloads But Won't Open
**Problem**: Downloaded book shows error when opening
**Solutions**:
1. Verify book format is supported (EPUB/KEPUB/PDF)
2. Check file isn't corrupted in Bookhoard
3. Try downloading via USB and opening
4. Check Kobo has sufficient free storage
5. Restart your Kobo device
#### Slow Download Speed
**Problem**: Books take too long to download
**Solutions**:
1. Ensure strong Wi-Fi signal (stay near router)
2. Use 5GHz Wi-Fi if your Kobo supports it
3. Close other apps using bandwidth
4. Download smaller books first
5. Consider using USB for large books
### OPDS vs USB Transfer
| Feature | OPDS (Wireless) | USB Transfer |
|---------|----------------|--------------|
| **Convenience** | ⭐⭐⭐⭐⭐ No cable needed | ⭐⭐ Requires cable |
| **Speed** | ⭐⭐⭐ Fast (Wi-Fi dependent) | ⭐⭐⭐⭐⭐ Very fast |
| **Bulk Transfer** | ⭐⭐⭐ One at a time | ⭐⭐⭐⭐⭐ Many at once |
| **Progress Sync** | ⭐⭐⭐⭐⭐ Automatic | ⭐⭐⭐⭐ After first sync |
| **Setup Complexity** | ⭐⭐⭐ Moderate | ⭐⭐⭐⭐⭐ Simple |
| **Reliability** | ⭐⭐⭐⭐ Good | ⭐⭐⭐⭐⭐ Excellent |
**Recommendation**: Use OPDS for convenience (1-5 books), use USB for bulk transfers (10+ books).
### Advanced OPDS Configuration
#### Custom Catalog Name
Change the name of the Bookhoard catalog on your Kobo:
```ini
[OPDS]
CatalogName=My Library
```
#### Auto-Download
Automatically download new books added to collections:
```ini
[OPDS]
AutoDownloadEnabled=true
AutoDownloadCollections=To Read,Recent
```
#### Download Quality
Choose between original EPUB or converted KEPUB:
```ini
[OPDS]
PreferredFormat=kepub # Options: epub, kepub, auto
```
## Sync Frequency Options
Configure how often Kobo syncs with Bookhoard:
```ini
[Sync]
# Sync frequency in minutes
SyncFrequency=5 # Sync every 5 minutes (recommended)
SyncFrequency=15 # Sync every 15 minutes
SyncFrequency=60 # Sync every hour
SyncFrequency=0 # Manual sync only
```
**Recommended**: `SyncFrequency=5` for near real-time sync
**Battery Saving**: `SyncFrequency=15` or `30` to reduce Wi-Fi usage
**Manual Only**: `SyncFrequency=0` sync only when you press "Sync Now"
## Manual Sync
To manually trigger a sync on your Kobo:
1. Connect Kobo to Wi-Fi
2. Go to **Settings** → **Sync & Backup**
3. Tap **Sync Now**
4. Wait for "Sync Complete" message
## Advanced Configuration
### Disable Kobo Store
To prevent Kobo from trying to connect to the official Kobo store:
```ini
[FeatureSettings]
KoboStoreSyncDisabled=true
```
### Custom Sync URL
If you're running Bookhoard with a custom domain or port:
```ini
[Sync]
# Custom domain
ServerURL=https://bookhoard.example.com/api/sync/kobo
# Custom port
ServerURL=http://192.168.1.100:9000/api/sync/kobo
# Localhost (for testing)
ServerURL=http://localhost:8765/api/sync/kobo
```
### HTTPS Configuration
If you have SSL/TLS configured on Bookhoard:
```ini
[Sync]
ServerURL=https://bookhoard.yourdomain.com/api/sync/kobo
```
Kobo will automatically trust the certificate if properly configured.
## Troubleshooting
### Sync Not Working
**Problem**: Sync doesn't happen automatically
**Solutions**:
1. Check Kobo is connected to Wi-Fi
2. Verify `AutoSyncEnabled=true` in config
3. Check `SyncFrequency` is not set to 0
4. Test with manual sync first
5. Check Bookhoard logs for connection attempts
### Connection Refused
**Problem**: "Connection refused" or "Server not reachable"
**Solutions**:
1. Verify Bookhoard is running on your computer
2. Check the server URL and IP address are correct
3. Ensure Kobo is on same Wi-Fi network as computer
4. Temporarily disable firewall to test
5. Try accessing Bookhoard URL in your browser first
### Authentication Failed
**Problem**: "Authentication failed" or "Invalid credentials"
**Solutions**:
1. Verify username and password in config file
2. Check your account is active and not locked
3. Try logging in to Bookhoard web interface
4. Ensure password doesn't contain special characters that need escaping
5. Reset password if needed
### Configuration File Not Saving
**Problem**: Changes to `Kobo eReader.conf` are lost
**Solutions**:
1. Make sure Kobo is ejected safely after editing
2. Check file permissions (should be writable)
3. Try a different text editor (Notepad++, VS Code, Sublime Text)
4. Backup the file before editing
5. On Mac, ensure you're not editing the package directly
### Sync Only Works Manually
**Problem**: Manual sync works, but auto-sync doesn't
**Solutions**:
1. Verify `AutoSyncEnabled=true` in config
2. Check `SyncFrequency` is not 0
3. Kobo only syncs when connected to Wi-Fi
4. Some Kobo models require Wi-Fi to be manually connected
5. Check Bookhoard device management page for connection errors
### Books Not Appearing in Kobo
**Problem**: Books added to Bookhoard don't show on Kobo
**Solutions**:
1. Kobo needs books to be sideloaded (manually transferred via USB)
2. Bookhoard syncs PROGRESS, not book files
3. Transfer book files to Kobo's `Documents` folder via USB
4. Kobo will then sync progress for those books with Bookhoard
5. Check that book formats are supported by Kobo
### Conflicts Not Showing
**Problem**: Conflicts between devices aren't being detected
**Solutions**:
1. Check Bookhoard Conflicts page
2. Ensure both devices have synced recently
3. Conflicts only detected when progress differs within 5 minutes
4. Manually sync both devices to trigger conflict detection
5. Review conflict resolution settings
## Security Best Practices
1. **Use HTTPS**: If deploying Bookhoard publicly, configure SSL/TLS
2. **Strong Password**: Use a secure password for your Bookhoard account
3. **Network Security**: Ensure your Wi-Fi network is secure (WPA2/WPA3)
4. **Regular Updates**: Keep Kobo firmware updated
5. **Device Authorization**: Only approve devices you recognize
## Network Configuration
### Local Network (Recommended)
For home use, keep Kobo and Bookhoard on the same local network:
```
Kobo Wi-Fi: 192.168.1.x
Bookhoard: 192.168.1.x
```
### Remote Access
For access outside your home network:
1. Set up port forwarding on your router (port 8765)
2. Configure SSL/TLS on Bookhoard
3. Use a dynamic DNS service for constant hostname
4. Update Kobo config with public URL:
```ini
[Sync]
ServerURL=https://yourdomain.com/api/sync/kobo
```
## Performance Optimization
### Battery Life
To extend Kobo battery life:
1. Use longer sync intervals (15-30 minutes)
2. Sync only on Wi-Fi (not cellular if your Kobo has it)
3. Disable unnecessary Kobo features
4. Keep Kobo in sleep mode when not reading
### Sync Speed
To improve sync speed:
1. Ensure strong Wi-Fi signal
2. Use local network (not remote access)
3. Keep Bookhoard and Kobo on same network
4. Close other apps using Wi-Fi bandwidth
5. Reduce number of books syncing at once
