      <h3>Welcome to GGn Upload Templator</h3>
      <p>
        This userscript helps automate your torrent upload workflow by
        extracting information from torrent filenames and auto-filling form
        fields.
      </p>

      <h4>Basic Workflow</h4>
      <ol>
        <li>
          <strong>Create a Template:</strong> Click "+ Create Template" and
          define a mask pattern that matches your torrent naming convention
        </li>
        <li>
          <strong>Define Variables:</strong> Use
          <code>\${variable}</code> syntax in your mask to extract data from
          torrent names
        </li>
        <li>
          <strong>Map Fields:</strong> Choose which form fields should be filled
          with which variables
        </li>
        <li>
          <strong>Apply Template:</strong> Select your template and click "Apply
          Template" to auto-fill the form
        </li>
      </ol>

      <h4>Example</h4>
      <p>For a torrent named: <code>PCWorld - Issue 05 - 01-2024.zip</code></p>
      <p>
        You could create a mask:
        <code>\${magazine} - Issue \${issue} - \${month}-\${year}.\${ext}</code>
      </p>
      <p>
        This extracts: magazine="PCWorld", issue="05", month="01", year="2024",
        ext="zip"
      </p>

      <h3>Creating and Managing Templates</h3>
      <p>
        Templates define how to extract information from torrent names and which
        form fields to fill.
      </p>

      <h4>Creating a Template</h4>
      <ol>
        <li>Click "+ Create Template" button</li>
        <li>Enter a descriptive template name</li>
        <li>
          Paste a sample torrent name (or select a torrent first and we'll use
          the extracted filename)
        </li>
        <li>Define your mask pattern (see Masks & Variables section)</li>
        <li>Select which form fields to fill and with what values</li>
        <li>Click "Save Template"</li>
      </ol>

      <h4>Editing Templates</h4>
      <p>
        Click "Manage" button, then click "Edit" next to any template. You can
        update the mask, field mappings, and other settings.
      </p>

      <h4>Cloning Templates</h4>
      <p>
        Use the "Clone" button to create a copy of an existing template as a
        starting point for a new one.
      </p>

      <h4>Field Selection</h4>
      <p>
        Use the "Show Unselected" button to see ignored fields. Check/uncheck
        fields to include or exclude them from the template.

      title: "Masks & Variables",
      content: html`
      <h3>Torrent Name Masks</h3>
      <p>
        Masks define patterns to extract variables from torrent filenames.
        Variables are defined using <code>\${variable_name}</code> syntax.
      </p>

      <h4>Variable Sources</h4>
      <p>Variables can be extracted from two sources:</p>
      <ul>
        <li>
          <strong>Torrent filename:</strong> The primary source for variable
          extraction using masks
        </li>
        <li>
          <strong>Torrent comment field:</strong> Define variables in the
          torrent file's comment using <code>variable=value</code> format
          (separated by semicolons, e.g. <code>var1=value1;var2=value2</code>)
        </li>
      </ul>

      <h4>Variable Syntax</h4>
      <p>
        <code>\${variable}</code> - Extracts any characters (non-greedy by
        default)
      </p>
      <p>
        <code>\${variable:pattern}</code> - Extracts characters matching a
        specific pattern. The pattern can be defined inline or in a named
        variable hint (see Variable Hints section for more details)
      </p>

      <h4>Pattern Types</h4>
      <ul>
        <li><code>#</code> - Matches a single digit (0-9)</li>
        <li><code>@</code> - Matches a single letter (a-z, A-Z)</li>
        <li><code>*</code> - Matches any alphanumeric character</li>
        <li><code>##</code> - Matches exactly 2 digits</li>
        <li><code>@@@</code> - Matches exactly 3 letters</li>
      </ul>

      <h4>Examples</h4>
      <p><code>\${artist} - \${album} [\${year:####}]</code></p>
      <p>Matches: "Artist Name - Album Title [2024]"</p>

      <p><code>\${magazine} Issue \${issue:##}</code></p>
      <p>Matches: "PCWorld Issue 05"</p>

      <h4>Literal Text</h4>
      <p>
        Any text outside of <code>\${...}</code> is treated as literal text that
        must match exactly.
      </p>

      <h4>Testing Masks</h4>
      <p>
        Use the Mask Sandbox tab to test your masks against multiple torrent
        names at once.

      <h3>Variable Hints</h3>
      <p>
        Hints help disambiguate extracted variables by validating or
        transforming them based on patterns or mappings.
      </p>

      <h4>Hint Types</h4>

      <h5>Pattern Hints</h5>
      <p>Validate that a variable matches a specific pattern:</p>
      <ul>
        <li><code>##</code> - Two digits</li>
        <li><code>####</code> - Four digits (year)</li>
        <li><code>@@@@</code> - Four letters</li>
      </ul>

      <h5>Regex Hints</h5>
      <p>Validate using regular expressions:</p>
      <ul>
        <li><code>v\\d+(\\.\\d+)*</code> - Version numbers like v1.2.3</li>
        <li><code>[A-Z]{2,4}</code> - 2-4 uppercase letters</li>
      </ul>

      <h5>Value Maps</h5>
      <p>Transform input values to output values:</p>
      <ul>
        <li>Input: "en" → Output: "English"</li>
        <li>Input: "fr" → Output: "French"</li>
      </ul>
      <p>
        Maps can be strict (reject unknown values) or non-strict (pass through
        unknown values).
      </p>

      <h4>Creating Hints</h4>
      <ol>
        <li>Go to "Variable Hints" tab</li>
        <li>Click "+ Add Hint"</li>
        <li>Name your hint (use the variable name it applies to)</li>
        <li>Choose hint type and define the pattern or mappings</li>
        <li>Save the hint</li>
      </ol>

      <h4>Mass Editing Maps</h4>
      <p>
        For value map hints, use "Mass Edit" or "Import" to quickly add many
        mappings in CSV or other delimited formats.
      </p>

      <h3>Optional Sections</h3>
      <p>
        Optional sections allow parts of your mask to be present or absent in
        torrent names.
      </p>

      <h4>Syntax</h4>
      <p>
        <code>{?optional content?}</code> - Everything between
        <code>{?</code> and <code>?}</code> is optional
      </p>

      <h4>Use Cases</h4>
      <ul>
        <li>
          Optional year in brackets: <code>\${title} {?[\${year}]?}</code>
        </li>
        <li>Optional version: <code>\${software} {?v\${version}?}</code></li>
        <li>
          Optional episode info:
          <code>\${series} {?S\${season}E\${episode}?}</code>
        </li>
      </ul>

      <h4>Examples</h4>
      <p>
        <strong>Mask:</strong>
        <code>\${artist} - \${album} {?[\${year}]?}</code>
      </p>
      <p><strong>Matches:</strong></p>
      <ul>
        <li>
          "Artist - Album [2024]" → artist="Artist", album="Album", year="2024"
        </li>
        <li>

      <h3>Applying Templates</h3>
      <p>
        Once you've created a template, you can apply it to auto-fill form
        fields.
      </p>

      <h4>Applying a Template</h4>
      <ol>
        <li>Select your template from the dropdown</li>
        <li>Click "Apply Template" button (or use the keybinding)</li>
        <li>Review the changes in the confirmation dialog</li>
        <li>Confirm to apply changes to the form</li>
      </ol>

      <h4>Variable Interpolation</h4>
      <p>Form field values can reference extracted variables:</p>
      <ul>
        <li><code>\${variable}</code> - Insert variable value</li>
        <li>
          <code>Static text \${variable}</code> - Mix static text with variables
        </li>
        <li><code>\${var1} - \${var2}</code> - Combine multiple variables</li>
      </ul>

      <h4>Variable Matching for Selects</h4>
      <p>
        For select/dropdown fields, you can match options based on extracted
        variables:
      </p>
      <ol>
        <li>Click "Match from variable: OFF" link next to a select field</li>
        <li>Choose match type (exact, contains, starts with, ends with)</li>
        <li>Enter the variable name (e.g., <code>\${category}</code>)</li>
        <li>
          The template will automatically select the matching option when
          applied
        </li>
      </ol>

      <h4>Field Previews</h4>
      <p>
        When creating/editing a template, field previews show what the final
        value will look like with sample data.
      </p>

      <h4>Confirmation Dialog</h4>
      <p>
        Before applying changes, you'll see which fields will be modified and
        their new values. This prevents accidental overwrites.

      <h3>Testing Masks</h3>
      <p>
        The Mask Sandbox lets you test mask patterns against multiple torrent
        names to verify they work correctly.
      </p>

      <h4>Using the Sandbox</h4>
      <ol>
        <li>Go to "Mask Sandbox" tab in the manager</li>
        <li>Enter your mask pattern</li>
        <li>Enter sample torrent names (one per line)</li>
        <li>View match results showing extracted variables</li>
      </ol>

      <h4>Match Results</h4>
      <p>For each sample, you'll see:</p>
      <ul>
        <li><strong>✓ Match:</strong> Variables successfully extracted</li>
        <li><strong>✗ No Match:</strong> Pattern didn't match</li>
        <li>
          <strong>Variable Values:</strong> All extracted variables with their
          values
        </li>
      </ul>

      <h4>Compiled Regex View</h4>
      <p>
        Click "Show compiled regex" to see the actual regular expression
        generated from your mask. Useful for debugging complex patterns.
      </p>

      <h4>Saving Test Sets</h4>
      <p>Save your mask and sample names as a test set for later reuse:</p>
      <ol>
        <li>Enter your mask and samples</li>
        <li>Click "Save" button</li>
        <li>Enter a name for your test set</li>
        <li>Load it later from the dropdown</li>
      </ol>

      <h4>Quick Testing from Template Creator</h4>
      <p>
        When creating/editing a template, click "Test mask in sandbox →" to jump
        directly to the sandbox with your current mask pre-filled.
