+# How to setup your development environment
+
+## Introduction
+
+This tutorial describes how to setup your development environment for building the Dojo CLI by detailing the prerequisites and dependencies needed.
+
+## Technologies
+
+The cli is built using [NodeJS](https://nodejs.org/en/) and [NPM](https://www.npmjs.com/).
+
+The programming language used is [Typescript](https://www.typescriptlang.org/) v5.
+
+
+## Prerequisites
+
+In order to build the cli you will need the following tools:
+- [NodeJS](https://nodejs.org/en/) (version 18 or higher)
+- [NPM](https://www.npmjs.com/) (version 10 or higher)
+
+Install NodeJS and NPM by following the instructions on the [official website](https://nodejs.org/en/download/package-manager).
+Or via Node Version Manager (NVM) by following the instructions on the [official website](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm).
+
+
+## Dependencies
+
+The CLI is packaged using [pkg](https://www.npmjs.com/package/pkg). 
+This means that all the dependencies are bundled in the final binary.
+
+Here are the main dependencies used by the cli (you don't need to install them manually or globally on your system):
+- [Axios](https://www.npmjs.com/package/axios): a promise-based HTTP client for the browser and Node.js. It is
+used to make HTTP(S) requests to the Dojo backend and Gitlab.
+- [Boxen](https://www.npmjs.com/package/boxen): used to display messages in a box in the terminal.
+- [Chalk](https://www.npmjs.com/package/chalk): used to add colors to the messages in the terminal.
+- [Commander.js](https://www.npmjs.com/package/commander): a library to write command-line interfaces.
+- [Dotenv](https://www.npmjs.com/package/dotenv): used to load environment variables from a .env file.
+- [Dotenv-vault](https://www.npmjs.com/package/dotenv-vault): a CLI to sync .env files across machines, 
+environments, and team members.
+- [Inquirer](https://www.npmjs.com/package/inquirer): used to ask perform to the interactive command line user interfaces.
+- [JsonWebToken](https://www.npmjs.com/package/jsonwebtoken): used to generate and validate [JSON Web Tokens](https://jwt.io/).
+- [ora](https://www.npmjs.com/package/ora): used to display elegantly in the terminal.
+- [zod](https://www.npmjs.com/package/zod): a TypeScript-first schema validation with static type inference. Used
+in the projet to validate json files created by the user.
+
+
+## Installation
+
+First of all, you need to clone the repository:
+```bash
+$ git clone ssh://git@ssh.hesge.ch:10572/dojo_project/projects/ui/dojocli.git
+```
+
+Then, you need to move to the project's directory:
+```bash
+$ cd NodeApp
+```
+
+To install the dependencies listed above you can use the following command in the base directory of the project:
+```bash
+$ npm install
+```
+
+
+## Environment variables
+
+Environment variables are used to store sensitive information such as API keys, passwords, etc.
+They are also used to store configuration information that can be changed without modifying the code.
+
+You can decrypt env var stored in the `.env.vault` file with the following commands in the project's main folder:
+```bash
+> npx dotenv-vault local keys
+ environment DOTENV_KEY
+ ─────────── ─────────────────────────────────────────────────────────────────────────
+ development dotenv://:key_1234@dotenv.local/vault/.env.vault?environment=development
+
+Set DOTENV_KEY on your server
+
+> npx dotenv-vault local decrypt dotenv://:key_1234@dotenv.local/vault/.env.vault?environment=development > .env.development
+```
+
+**The `.env.keys` file have to be requested to the project maintainer: [Michaël Minelli](mailto:dojo@minelli.me).**
+
+
+## Run the cli
+
+To run the cli (in dev mode) you can use the following command in the base directory of the project:
+```bash
+$ npm run start:dev -- COMMAND
+```
+Where `COMMAND` is the command you want to run.
+
+For example, if you want to test the exercise creation command you can use the following command:
+```bash
+$ npm run start:dev -- exercise create -a "Technique de compilation - TP" --members_username michael.minelli
+```
