+# 💡 Contributing
+
+## Types of contributions :
+
+- [Submit a challenge instructions](challenge-instructions)
+- [Share a solution for an already existing challenge](solution-for-an-already-existing-challenge)
+- [Add a language available for testing the code](language-available-for-testing-the-code) 
+- [Correct a spelling error](spelling-error)
+
+## Challenge instructions
+
+After running the command `npm run create-challenge` (see Installation & Usage part of [README.md](../README.md)).
+
+You should have a new folder called the name of your challenge in [challenges](./challenges) folder.
+
+### Structure and purpose of each files :
+
+- `README.md` : explain what the solution function should do (the instructions).
+- `input-output.json` : An array of possible input/output. This file allows you to test solutions.
+
+    Example of file :
+    ```json 
+    [
+        {
+            "input": ["arg"],
+            "output": "Hello world arg!"
+        },
+        {
+            "input": ["Divlo"],
+            "output": "Hello world Divlo!"
+        }
+    ]
+    ```
+    Each object has a "input" key, an array where each item is an argument passed to the solution function when it's executed. The "output" key is the expected output with the given input.
+- `solutions` folder where there are all solutions for this specific challenge.
+
+## Solution for an already existing challenge
+
+After running the command `npm run create-solution` (see Installation & Usage part of [README.md](../README.md)).
+
+You should have a new folder called the name of your solution in the challenge folder then you can write your solution in the solution file.
+You need to name your parameters of the function (see the instruction of the challenge).
+
+When you feel it's right, you would need to test your code against `input-output.json` file to see if it's a valid solution..
+Run this command `npm run test [challenge-name] [solution-name]`.
+
+## Language available for testing the code
+
+Before to add a new language, you should understand :
+
+[/scripts/languages-wrapper](../scripts/languages-wrapper) folder contains all the files needed to execute solutions. Each programming challenge has a execute file, this execute file will be copied in the `temp` folder with the solution file.
+
+Steps to add a new language : 
+
+1. Code the execute file in the appropriate language
+
+    Algorithm of the execute file : 
+
+    - Import the solution function (same  directory, ignore errors)
+    - Read the `./input.json` files and convert it as JSON (not plain text string)
+    - Execute the solution function imported with the inputs as arguments
+    - Create and write a new file called `./output.json`, with the output result of the solution function
+
+    Example in javascript with node.js ([execute.js](../scripts/languages-wrapper/execute.js)) : 
+    ```javascript 
+    const path = require('path')
+    const fs = require('fs').promises
+    const solution = require('./solution')
+
+    const inputPath = path.join(__dirname, 'input.json')
+    const outputPath = path.join(__dirname, 'output.json')
+
+    const main = async () => {
+        const inputFile = await fs.readFile(inputPath)
+        const inputJSON = JSON.parse(inputFile)
+
+        const result = solution.apply(null, inputJSON)
+        await fs.writeFile(outputPath, JSON.stringify(result))
+    }
+
+    main()
+    ```
+
+1. Add the language in the `_languages.json` file as a new object of the array. Example for JavaScript : 
+    ```json 
+    {
+        "name": "JavaScript",
+        "extension": ".js",
+        "launch": "node"
+    }
+    ```
+1. Create a new solution file with the default basic boilerplate code in `/scripts/languages-wrapper/templates`. Example : `solution.js`:
+    ```js
+    function solution () {
+    
+    }
+
+    module.exports = solution
+    ```
+1. Add the language in the language available in [README.md](../README.md) file.
+
+
+
+## Spelling error
+
+Correct spelling errors, in the README or CONTRIBUTING files.
+
+Thank you for your support!

+
+## 📜 About
+
+**programming-challenges** brings together lots of programming exercises and challenges to improve your algorithmic logic.
+
+Each challenge has its **solutions**, its **instructions** and **input/output examples** so you can try to solve them on your own. See [challenges](./challenges) folder.
+
+## ✅ Programming languages available
+
+`npm run test` command will only work with these languages :
+
+- JavaScript and TypeScript (Node.js >= 12)
+- Python >= 3.8
+
+## 🚀 Installation & Usage (CLI)
+
+To easily create **new challenges instructions, solutions and test** your code, I made a **CLI tool** made with Node.js and TypeScript.
+
+### Requirements :
+
+- Node.js >= 12
+
+Then you need to run `npm install` in the root folder to install needed packages, you can now use one of these commands : 
+
+- ### `npm run create-challenge`
+
+  Create the basic files needed for a new challenge. It will ask you some questions and you will be ready to write the instructions and `input-output.json`. Please read [CONTRIBUTING.md](./.github/CONTRIBUTING.md).
+
+- ### `npm run create-solution`
+
+  Create the basic files needed for a new solution for a challenge. It will ask you some questions and you will be ready to write your solution in the available programming languages (see above). If you wish to submit to everyone your solution. Please read [CONTRIBUTING.md](./.github/CONTRIBUTING.md).
+
+- ### `npm run test [challenge-name] [solution-name]`
+
+  Test if the solution is correct and display where it succeeds and fails with the inputs provided, the output of your function and the expected output.
+
+  Example : `npm run test hello-world python-hello`
+
+## 💡 Contributing
+
+Feel free to submit your challenges, your solutions or even a simple spelling mistake.
+
+Everyone can contribute to the improvement of the project! The steps to contribute can be found in the [CONTRIBUTING.md](./.github/CONTRIBUTING.md) file.
