+## usage
+
+### using nix
+
+To install the needed library [marp](https://marp.app/), enter the development environment with [`nix-shell`](https://nixos.org/).
+
+If you want to do that automatically on entering this directory:
+
+- [Set up `direnv`](https://github.com/nix-community/nix-direnv#installation)
+- Run `direnv allow` in the directory where repository is stored on your machine
+
+Then, compile the slides:
+
+```sh
+marp -I .
+```
+... then open the resulting `.html` file in your browser.
+
+To automatically rebuild on changes, use:
+
+```sh
+watchexec -w ./. -- marp -I .
+```
+
+### without nix
+
+requires:
+
+- [Node.js](https://nodejs.org/)
+- [Yarn](https://yarnpkg.com/)
+
+```sh
+$ yarn install
+$ yarn marp -I .
+```
