+   This document describes the development process of Mezzotint tool.
+
+Contributing
+============
+
+It's as simple as that: every input matters as a contribution, including your candid subjective feedback `(just don't overdo it)`.
+
+Although Mezzotint is coded in Rust, if you're not comfortable developing in this language, you can still significantly contribute to the project by using it and reporting any encountered issues:
+
+- Features, those are still missing
+- Bug reports and failures it produces
+- Corner cases where it still fails
+
+Developing
+----------
+
+If you're looking to create a new feature, the optimal workflow would be this:
+
+1. Open an issue as a feature you want to have
+2. Let's discuss it there to shape out how it will look like
+3. You implement it and make a Pull Request
+
+Tooling
+-------
+
+If you haven't learned subjectively `world-best editor <https://www.gnu.org/s/emacs>`__ just yet, then alternatively the Visual Studio Code would also do for you.
+
+Assuming you are going to use VSC, install `Rust Analyser <https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer>`__ extension and everything it requires (``rustc``, ``cargo``, ``rustup`` etc). Furthermore, please configure your Visual Studio to automatically reformat your file using the default Rust formatter whenever you save it.
