 ## Setting up your own binary crate
 
-TODO
+If you have a custom board, you might be interested in setting up a new binary crate for your
+project. These steps aim to provide a complete list to get a binary crate working to flash
+your custom board.
+
+The hello world of embedded development is usually to blinky a LED. This example
+is contained within the
+[examples folder](https://egit.irs.uni-stuttgart.de/rust/va416xx-rs/src/branch/main/examples/simple/examples/blinky.rs).
+
+1. Set up your Rust cross-compiler if you have not done so yet. See more in the [build chapter](#Building)
+2. Create a new binary crate with `cargo init`
+3. To ensure that `cargo build` cross-compiles, it is recommended to create a `.cargo/config.toml`
+   file. A sample `.cargo/config.toml` file is provided in this repository as well
+4. Copy the `memory.x` file into your project. This file contains information required by the linker.
+5. Copy the `blinky.rs` file to the `src/main.rs` file in your binary crate
+6. You need to add some dependencies to your `Cargo.toml` file
+
+   ```toml
+	[dependencies]
+	cortex-m = "<Compatible Version>"
+	cortex-m-rt = "<Compatible Version>"
+	panic-halt = "<Compatible Version>"
+	embedded-hal = "<Compatible Version>"
+
+	[dependencies.va416xx-hal]
+	version = "<Most Recent Version>"
+	features = ["rt"]
+   ```
+
+6. Build the application with `cargo build`
+
+7. Flashing the board might work differently for different boards and there is usually
+   more than one way. You can find example instructions in primary README.
