+# `stm32-template`
+
+> A template for building applications for STM32 microcontrollers
+
+## Dependencies
+
+To build embedded programs using this template you'll need:
+
+- The `cargo generate` subcommand. [Installation
+  instructions](https://github.com/cargo-generate/cargo-generate#installation).
+``` console
+$ cargo install cargo-generate
+```
+
+- Flash and run/debug tools:
+``` console
+$ cargo install probe-rs --features cli
+```
+
+- `rust-std` components (pre-compiled `core` crate) for the ARM Cortex-M
+  targets. Run:
+  
+``` console
+$ rustup target add thumbv6m-none-eabi thumbv7m-none-eabi thumbv7em-none-eabi thumbv7em-none-eabihf
+```
+
+## Instantiate the template.
+
+1. Run and enter project name
+``` console
+$ cargo generate --git https://github.com/burrbull/stm32-template/
+ Project Name: app
+```
+
+2. Specify **chip product name** and answer on several other guide questions.
+
+3. Your program is ready to compile:
+``` console
+$ cargo build --release
+```
+
+## Flash and run/debug
+
+You can flash your firmware using one of those tools:
+
+- `cargo flash --release` — just flash
+- `cargo run --release` — flash and run using `probe-rs run` runner or `probe-run` runner (deprecated) which you can set in `.cargo/config.toml`
+- `cargo embed --release` — multifunctional tool for flash and debug
+
+You also can debug your firmware on device from VS Code with [probe-rs](https://probe.rs/docs/tools/vscode/) extention or with `probe-rs gdb` command.
+You will need SVD specification for your chip for this. You can load patched SVD files [here](https://stm32-rs.github.io/stm32-rs/).
