 selfoss makes use of many libraries to make our job as developers easier. To install them, you will need appropriate package managers. The server side uses [composer](https://getcomposer.org/) for PHP libraries and the client side uses [npm](https://www.npmjs.com/get-npm) for the JavaScript world.
 
-Then you will be able to run `npm run install-dependencies` to install the libraries, and `npm run dev` to start a program that will rebuild client-side assets when needed.
+Then you will be able to run <code><a href="https://github.com/casey/just">just</a> install-dependencies</code> to install the libraries, and `just dev` to start a program that will rebuild client-side assets when needed.
 
 To run the server side you will need at least [PHP](https://www.php.net/downloads) to be able to run the development server using `php -S 127.0.0.1:8000 run.php`. It would be also nice to have an array of database servers (MySQL and PostgreSQL) and web servers (Apache httpd and nginx) but the server built into PHP and SQLite will suffice for small changes.
