 # STM32F0 Crankshaft Monitor
 
 Real-time crankshaft sensor monitoring system built with Rust and [embassy-rs](https://github.com/embassy-rs) framework for STM32F0 microcontrollers.
+
+## Useful Commands
+
+### Development
+
+- Run with debug features using `probe-run`:
+  ```bash
+  cargo run --profile dev --bin crankshaft
+  ```
+
+### Analysis
+
+- Analyze binary size with detailed section breakdown:
+  ```bash
+  cargo size --bin crankshaft --release --no-default-features -- -A
+  ```
+
+- Inspect read-only data section:
+  ```bash
+  cargo objdump --bin crankshaft --release --no-default-features -- -s -j .rodata | vi
+  ```
+
+> **Note**: Using `--no-default-features` disables debug functionality for smaller binary size and better performance.
+
+### Release
+
+- Flash release build:
+  ```bash
+  cargo embed --release --bin crankshaft --no-default-features
+  ```
+
+- Run release build:
+  ```bash
+  cargo run --profile release --bin crankshaft --no-default-features
+  ```
