-# 02_esp-idf-no-std
-
-This is an example of using ESP-IDF using no std using templates provided by https://github.com/esp-rs/esp-idf-template.
-When flashed to a device, the application just adjusts the intensity of the on-board LED for visual verification that flashing works correctly.
-
-Steps used to generate this project
-
-```bash
-cargo install cargo-generate
-cargo generate --git https://github.com/esp-rs/esp-idf-template.git --name esp-idf-rust-no-std -d mcu=esp32 -d std=false
-```
-
-Steps to build and flash this project
-
-```bash
-# Install espflash if you don't have it already
-cargo install espflash
-
-# Export esp-idf build environment
-. ~/export-esp.sh
-
-# Build and flash to the device
-cargo build
-cargo run
-```
-
