+# Repository Guidelines
+
+## Project Structure & Module Organization
+NeuralSynth is a JUCE-based synthesizer plugin. Core runtime code lives in `Source/`, with `PluginProcessor.*` orchestrating audio/MIDI flow, `PluginEditor.*` driving the UI, `SynthVoice.*` implementing per-voice DSP, and helper headers such as `AudioEngine.h` and `NeuralSharedParams.h` exposing shared state. JUCE-generated scaffolding sits in `JuceLibraryCode/`; regenerate it through `NeuralSynth.jucer` rather than editing by hand. Platform build assets are under `Builds/` (for example `Builds/LinuxMakefile/`), and finished binaries default to `Builds/LinuxMakefile/build/`. Install scripting for Windows lives in `NeuralSynth.iss`.
+
+## Build, Test, and Development Commands
+- `cd Builds/LinuxMakefile && make CONFIG=Debug` compiles the standalone app and VST3 with debug symbols.
+- `cd Builds/LinuxMakefile && make CONFIG=Release` builds optimized artefacts for distribution.
+- `cd Builds/LinuxMakefile && make clean` removes intermediate objects when builds misbehave.
+- `./Builds/LinuxMakefile/build/NeuralSynth` launches the standalone target; VST3 binaries appear in `Builds/LinuxMakefile/NeuralSynth.vst3` and copy into `~/.vst3` when the Makefile post-build step runs.
+
+## Coding Style & Naming Conventions
+C++ sources use 4-space indentation, brace-on-new-line functions, and JUCE’s `juce::` namespace types. Prefer `PascalCase` for classes (e.g., `NeuralSynthAudioProcessor`), camelCase for methods and members (`prepareToPlay`, `audioEngine`), and suffix queues/collectors clearly (`AudioBufferQueue`, `ScopeDataCollector`). Match existing lambda formatting in `SynthVoice.cpp`, keep includes sorted locally, and avoid editing generated files under `JuceLibraryCode/`.
+
+## Testing Guidelines
+Automated tests are not yet configured; rely on manual validation in the standalone app or a DAW host. After each change, rebuild and audition key features: oscillator switching, chorus/delay/reverb chains, parameter automation, and MIDI input. For DSP tweaks, monitor the oscilloscope components linked to the buffer queues to confirm signal stability. Document ad-hoc test coverage in your pull request until formal tests are added.
+
+## Commit & Pull Request Guidelines
+Follow the existing concise, imperative commit style (`Add chorus modulation`, `Fix voice detune`). Scope each commit to a logical change and format messages as a single summary line. Pull requests should describe the motivation, outline testing performed, and link issues when relevant. Include platform notes (Linux, Windows installer) and screenshots or audio clips for UI-affecting or sonic changes so reviewers can assess impact quickly.

+ Important Note!!
+ ================
+
+The purpose of this folder is to contain files that are auto-generated by the Projucer,
+and ALL files in this folder will be mercilessly DELETED and completely re-written whenever
+the Projucer saves your project.
+
+Therefore, it's a bad idea to make any manual changes to the files in here, or to
+put any of your own files in here if you don't want to lose them. (Of course you may choose
+to add the folder's contents to your version-control system so that you can re-merge your own
+modifications after the Projucer has saved its changes).

+ Important Note!!
+ ================
+
+The purpose of this folder is to contain files that are auto-generated by the Projucer,
+and ALL files in this folder will be mercilessly DELETED and completely re-written whenever
+the Projucer saves your project.
+
+Therefore, it's a bad idea to make any manual changes to the files in here, or to
+put any of your own files in here if you don't want to lose them. (Of course you may choose
+to add the folder's contents to your version-control system so that you can re-merge your own
+modifications after the Projucer has saved its changes).
