+# Signal
+
+A friendly music sequencer application built with web technology.
+
+## Goals
+
+- Cross-platform
+- NOT complicated UI
+- MIDI format compatible
+
+## Concepts
+
+Recording and finishing is the role of the DAW, making it an app that can be used quickly at the composition and sketching stages.
+The following restrictions are given so that you can concentrate on composing without being distracted by the selection of sound sources and adjustment of effects.
+
+- No high-quality sound
+- No Fx
+- Make it as lightweight as possible
+
+## Contribution
+
+Any kind of contribution is welcome.

+## Automated Performance Measurement Script
+
+By using puppeteer, measure performance metrics automatically.
+
+## Usage
+
+```sh
+cd path/to/signal
+npm start
+```
+
+Then run puppeteer
+
+```sh
+cd path/to/signal/scripts/perf
+npm start
+```
+
+## Test contents
+
+1. Launch the browser
+2. Open test.mid
+3. Play the entire song
+4. Shutdown the browser
+5. Save the metrics as a JSON file in the output directory
