+## Build/Lint/Test Commands
+
+This is a minimal LMS plugin with no automated tests. No build/lint/test commands exist.
+
+## Code Style Guidelines
+
+### Perl (Plugin.pm)
+- Keep minimal - only required `initPlugin {}` function
+- Use standard Perl package declaration: `package Plugins::MobileTranscode::Plugin;`
+- End file with `1;` as required by Perl modules
+
+### XML Files (install.xml, repo.xml)
+- Follow existing indentation (2 spaces)
+- Maintain exact structure for LMS compatibility
+- Version format: X.Y.Z (semantic versioning)
+
+### custom-convert.conf
+- Use tabs for indentation (LMS requirement)
+- Format: `[source] [dest] [model] [player]`
+- Comments start with `#`
+- Capability flags in comments: I/F/T/U/D
+- Pipeline commands use `[tool]` syntax with LMS variables
+
+### Naming Conventions
+- Model names: PascalCase (e.g., LyrPlay, YourApp)
+- Files: kebab-case for README, lower-case for config
+- Plugin namespace: Plugins::MobileTranscode::Plugin
+
+### Critical Rules
+- SHA1 in repo.xml must exactly match release zip
+- Always update install.xml version first before release
+- Test with actual mobile clients - no automated validation available
