-# Probo Collector
+# Probo 💯
 
-A backend to collect quizzes in a RESTful way.
+Probo is a software tool designed for creating, managing, and administering
+exams based on multiple-choice quizzes. Its data storage approach is entirely
+file-based, git-friendly, eliminating the need for an external database. Exam
+sessions are delivered to participants via a responsive web interface.
+
+# Features
+
+* Uses plain text files for storage
+* Uses Markdown for quiz creation
+* Uses CSV for participant details
+* Configures exam sessions via TOML
+* It's a self-contained executable for easy deployment
+* Features a responsive web interface for quiz administration
+* Supports scripting with the [goja](https://github.com/dop251/goja) JavaScript engine
+
+# Quick Start
+
+Begin by installing Probo:
+
+```
+go get git.andreafazzi.eu/andrea/probo
+```
+
+To start using the software, create a directory:
+
+```bash
+mkdir $HOME/myprobo
+```
+
+Once inside the directory, execute the `probo init` command:
+
+```bash
+cd myprobo
+probo init
+```
+
+This will generate a file and folder structure. The `datasource` folder contains
+files for initiating quiz creation, participant registration, and test
+construction. Below are the three necessary commands to build your first test.
+
+```bash
+probo create participants datasource/participants/participants_math.csv
+probo create quizzes datasource/quizzes/quizzes_math.md
+probo create participants datasource/sessions/math_test.toml
+```
+
+The previous commands will generate an exam session, which includes students
+listed in `participants_math.csv`. The quizzes for each participant's session
+are selected from the `quizzes_math.md` file. Exam session characteristics are
+configured within the `math_test.toml` file. The `programs/shuffled.js` script
+defines the criteria for populating participants' exams.
+
+After generating the exam session, you can administer tests to participants via
+a web interface. Probo allows you to launch a web server from your working
+directory using the command:
+
+```bash
+probo serve
+```
+
+Accessing `http://localhost:3000` in a browser and entering student or
+administrator credentials will grant access to the testing sessions.
