+## Development Flow
+
+If you make changes to Rust code and want to compile, use [cargo build](https://doc.rust-lang.org/cargo/commands/cargo-build.html). This will update Rust binaries such as dynamo-run.
+
+```bash
+cd /home/ubuntu/dynamo && cargo build --locked --profile dev
+```
+
+Before pushing code to GitHub, remember to run `cargo fmt` and `cargo clippy`
+
+If you make changes to Rust code and want to propagate to Python bindings then can use [maturin](https://www.maturin.rs/#usage) (pre-installed). This will update the Python bindings with your new Rust changes.
+
+```bash
+cd /home/ubuntu/dynamo/lib/bindings/python && maturin develop
+```
