+# TRMNL Plugin Development Guidelines
+
+## Project Overview
+This is a TRMNL platform plugin for displaying room data from Google Sheets on connected devices. The plugin uses Liquid templating for the frontend and YAML for configuration.
+
+## File Structure
+- `full.liquid` - Main Liquid template file for rendering room data
+- `settings.yml` - Plugin configuration including API endpoints and custom fields
+- `MeetingRooms-sample-data.json` - Sample data structure reference
+
+## Code Style Guidelines
+
+### Liquid Templating
+- Use Liquid syntax for data binding and conditional logic
+- Follow existing naming conventions: use snake_case for variables
+- Keep HTML structure clean and semantic
+- Use TRMNL-specific classes for styling (layout, columns, grid, etc.)
+
+### YAML Configuration
+- Use YAML format for all configuration files
+- Follow existing key naming conventions (snake_case)
+- Include proper descriptions for custom fields
+- Use string quotes for all string values
+
+### General Development
+- No build/test commands - this is a static plugin
+- Validate Liquid syntax by testing in TRMNL platform
+- Ensure Google Sheets API URLs are correct and accessible
+- Test with various device IDs using TRMNL_ID matching
+
+### Testing
+- Test by deploying to TRMNL platform with different device IDs
+- Verify data loads from Google Sheets correctly
+- Check responsive behavior on TRMNL devices
+- Validate fallback logo displays when no data is available
+
+## Key Components
+- Device ID matching via `trmnl.plugin_settings.custom_fields_values.device_id`
+- Data filtering using `where` filter in Liquid
+- Google Sheets integration via opensheet.elk.sh API

 **Functionality:**
 
-The plug-in functions by linking to a Google Sheet. The sheet contains the room data that will be displayed on the TRMNL device. The link is established through a matching Spreadsheet ID, ensuring that the correct data is displayed on the intended device.

 **New Feature - Not In Use Mode:**
-Each display can now be marked as "Not In Use" by setting the `not_in_use` field to "TRUE" in the spreadsheet. When enabled, the display will show the Cedarmore logo instead of room data, allowing for easy identification of unavailable displays. Setting `not_in_use` to "FALSE" will show the normal room information.
