+# CVIssueCount
+
+A ComicRack Community Edition plugin that fetches issue counts from ComicVine and updates your comic library.
+
+## Features
+
+- Fetches issue count for comic volumes from ComicVine API
+- **Local database support**: Use a local SQLite database (`localcv.db`) for faster lookups without API calls
+- **Configurable settings**: API key, delay between requests, and data source preferences
+- Updates both the `Count` field and a custom `comicvine_issue_count` field
+- Progress bar with cancel support
+
+## Installation
+
+1. Download the latest release from the [Releases](../../releases) tab
+2. Extract the contents to your ComicRack scripts folder:
+   ```
+   %APPDATA%\cYo\ComicRack Community Edition\Scripts\CVIssueCount\
+   ```
+3. Restart ComicRack
+
+### Required Files
+
+```
+CVIssueCount/
+├── CVIssueCount.py
+├── CVIssueCount.png
+├── System.Data.SQLite.dll      (required for local DB)
+├── x64/
+│   └── e_sqlite3.dll           (required for local DB on 64-bit)

+└── localcv.db                  (optional - local ComicVine database)
+```
+
+### Setting up SQLite for Local Database
+
+To use the local database feature, you need the SQLite libraries:
+
+1. **System.Data.SQLite.dll**
+   - Download from [NuGet - System.Data.SQLite](https://www.nuget.org/api/v2/package/System.Data.SQLite/)
+   - Extract the `.nupkg` file (it's a zip file)
+   - Copy `lib/net471/System.Data.SQLite.dll` to the plugin folder
+
+2. **e_sqlite3.dll (native library)**
+   - Download from [NuGet - SourceGear.sqlite3](https://www.nuget.org/api/v2/package/SourceGear.sqlite3/)
+   - Extract the `.nupkg` file
+   - Create `x64` and `x86` folders in the plugin directory
+   - Copy `runtimes/win-x64/native/e_sqlite3.dll` → `x64/e_sqlite3.dll`
+   - Copy `runtimes/win-x86/native/e_sqlite3.dll` → `x86/e_sqlite3.dll`
+
+### Getting the Local Database
+
+The `localcv.db` file contains an offline copy of ComicVine volume data. Download it from:
+
+**[Offline ComicVine Database on Reddit](https://old.reddit.com/r/comicrackusers/comments/1q7rex8/here_it_is_an_offline_comicvine_tagger_for/)**
+
+Place `localcv.db` in the plugin folder after downloading.
+
+## Usage
+
+### Running the Plugin
+
+1. Select one or more comics in your library
+2. Right-click -> Automation -> CVIssueCount - or click the icon in the menu bar
+3. Click Start to begin fetching issue counts
+
+### Settings
+
+Access settings via:
+- Settings button in the main dialog
+
+#### Available Settings
+
+| Setting | Description |
+|---------|-------------|
+| **ComicVine API Key** | Your ComicVine API key (get one at [comicvine.gamespot.com/api](https://comicvine.gamespot.com/api/)) |
+| **Skip API if not in local DB** | Only use the local database; skip volumes not found locally |
+| **Always use API** | Ignore local database and always fetch from ComicVine API |
+| **API delay (seconds)** | Delay between API requests (default: 10). Set to 0 to disable |
+
+## Local Database
+
+For faster lookups without API rate limits, you can use a local SQLite database containing ComicVine volume data.
+
+The database should be named `localcv.db` and placed in the plugin folder. It must have a `cv_volume` table with at least these columns:
+- `id` - ComicVine volume ID
+- `count_of_issues` - Number of issues in the volume
+
+### Data Source Priority
+
+1. If local database exists and "Always use API" is unchecked → check local DB first
+2. If not found in local DB and "Skip API" is unchecked → fall back to API
+3. If "Always use API" is checked → skip local DB entirely
+
+## Requirements
+
+- ComicRack Community Edition
+- Comics must have `comicvine_volume` custom field populated (e.g., via ComicVine Scraper)
+- For API usage: Valid ComicVine API key
+- For local DB: SQLite DLLs included in the release
+
+## Troubleshooting
+
+### "System.Data.SQLite.dll not found"
+Make sure `System.Data.SQLite.dll` is in the plugin folder.
+
+### "Unable to load DLL 'e_sqlite3'"
+Ensure the `x64` and `x86` folders contain `e_sqlite3.dll`.
+
+### API rate limiting
+ComicVine has API rate limits. Increase the API delay in settings if you're getting errors.
