+# Venera Headless Mode
+
+Venera's headless mode allows you to run key features from the command line, making it easy to automate tasks and integrate with other tools. This document outlines the available commands and their usage.
+
+## How to Use
+
+To activate headless mode, use the `--headless` flag when running the Venera executable, followed by the desired command.
+
+```bash
+venera --headless <command> [subcommand] [options]
+```
+
+## Global Options
+
+- **`--ignore-disheadless-log`**: Suppresses log output, providing a cleaner output for scripting.
+
+## Commands
+
+### `webdav`
+
+Manage WebDAV data synchronization.
+
+- **`webdav up`**: Uploads your local configuration to the WebDAV server.
+- **`webdav down`**: Downloads and applies the remote configuration from the WebDAV server.
+
+**Example:**
+
+```bash
+venera --headless webdav up
+```
+
+### `updatescript`
+
+Update comic source scripts.
+
+- **`updatescript all`**: Checks for and applies all available updates for your comic source scripts.
+
+**Example:**
+
+```bash
+venera --headless updatescript all
+```
+
+**Output Format:**
+
+The `updatescript` command provides detailed progress and a final summary.
+
+**Progress Logs:**
+
+- **`Progress`**: Indicates a successful update for a single script.
+- **`ProgressError`**: Indicates a failure during a script update.
+
+**Example `Progress` Log:**
+
+```json
+{
+  "status": "running",
+  "message": "Progress",
+  "data": {
+    "current": 1,
+    "total": 5,
+    "source": {
+      "key": "source-key",
+      "name": "Source Name",
+      "version": "1.0.0",
+      "url": "https://example.com/source.js"
+    }
+  }
+}
+```
+
+**Final Summary:**
+
+A summary is provided at the end, detailing the total number of scripts, how many were updated, and how many failed.
+
+```json
+{
+  "status": "success",
+  "message": "All scripts updated.",
+  "data": {
+    "total": 5,
+    "updated": 4,
+    "errors": 1
+  }
+}
+```
+
+### `updatesubscribe`
+
+Update your subscribed comics and retrieve a list of updated comics.
+
+- **`updatesubscribe`**: Checks all subscribed comics for updates.
+- **`updatesubscribe --update-comic-by-id-type <id> <type>`**: Updates a single comic specified by its `id` and `type`.
+
+**Example:**
+
+```bash
+# Update all subscriptions
+venera --headless updatesubscribe
+
+# Update a single comic
+venera --headless updatesubscribe --update-comic-by-id-type "comic-id" "source-key"
+```
+
+## Output Format
+
+All headless commands output JSON objects prefixed with `[CLI PRINT]`. This structured format allows for easy parsing in automated scripts. The JSON object always contains a `status` and a `message`. For commands that return data, a `data` field will also be present.
+
+### `updatesubscribe` Output
+
+The `updatesubscribe` command provides detailed progress and final results in JSON format.
+
+**Progress Logs:**
+
+During an update, you will receive `Progress` or `ProgressError` messages.
+
+- **`Progress`**: Indicates a successful step in the update process.
+- **`ProgressError`**: Indicates an error occurred while updating a specific comic.
+
+**Example `Progress` Log:**
+
+```json
+{
+  "status": "running",
+  "message": "Progress",
+  "data": {
+    "current": 1,
+    "total": 10,
+    "comic": {
+      "id": "some-comic-id",
+      "name": "Some Comic Name",
+      "coverUrl": "https://example.com/cover.jpg",
+      "author": "Author Name",
+      "type": "source-key",
+      "updateTime": "2023-10-27T12:00:00Z",
+      "tags": ["tag1", "tag2"]
+    }
+  }
+}
+```
+
+**Example `ProgressError` Log:**
+
+```json
+{
+  "status": "running",
+  "message": "ProgressError",
+  "data": {
+    "current": 2,
+    "total": 10,
+    "comic": {
+      "id": "another-comic-id",
+      "name": "Another Comic Name",
+      ...
+    },
+    "error": "Error message here"
+  }
+}
+```
+
+**Final Output:**
+
+Once the update process is complete, a final JSON object is returned with a list of all comics that have been updated.
+
+```json
+{
+  "status": "success",
+  "message": "Updated comics list.",
+  "data": [
+    {
+      "id": "some-comic-id",
+      "name": "Some Comic Name",
+      "coverUrl": "https://example.com/cover.jpg",
+      "author": "Author Name",
+      "type": "source-key",
+      "updateTime": "2023-10-27T12:00:00Z",
+      "tags": ["tag1", "tag2"]
