+Install Rust via rustup (required for Cargo lockfile v4 support). Use the default (full) profile, not the minimal one, as the full toolchain is needed to build the Rust plugins:
+```shell
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+```
+
+Install uv for Python dependency management:
+```shell
+curl -LsSf https://astral.sh/uv/install.sh | sh
 ```
 
+After installing uv, restart your shell or run `source ~/.bashrc` to ensure `uv` is in your PATH.
+
+Make sure you have [bitcoind](https://github.com/bitcoin/bitcoin) available to run.
