-[![Continuous Deployment](https://api.netlify.com/api/v1/badges/021c39c6-1018-4e3f-98e2-f808b4ea8f6d/deploy-status)](https://app.netlify.com/sites/epic-nightingale-99f910/deploys)
+# Front-end election web application using NextJs
 
-# Voting application in React
 
-A demo is available at [our website](http://demo.mieuxvoter.fr/).
+[![Netlify Status](https://api.netlify.com/api/v1/badges/e5e19870-2d67-4082-973e-593f58c56f87/deploy-status)](https://app.netlify.com/sites/mv-front-react/deploys)
 
-## Installation
 
-1. Copy `.env` file into `.env.local` and set there environment variables.
-2. Install [yarn](https://classic.yarnpkg.com/en/docs/install/#debian-stable).
-3. Install dependencies:
-```bash
-$ cd mvfront-react
-$ yarn install
-```
+:ballot_box: This project is going to be the default front-end for our [election application](https://app.mieuxvoter.fr).
 
-## Translation
+:computer: It is connected to our [back-end](https://github.com/MieuxVoter/mv-api-server-apiplatform). The back-end is used for storing the votes and computing the majority judgment ranking. You can use our back-end free of charge, but you can also start your own instance of the back-end using our Dockerfiles.
 
-We are welcoming translations of the application in any language.
-To add a new language, copy a [language folder](./public/locale/i18n/en/) into a new folder with your language as a name.
-Then, replace values in the JSON files. 
+:incoming_envelope: The front-end is responsable for sending the invitation mails. You can find the mail templates [on the functions folder](./functions/send-invite-email).
 
-To compile them, launch: `$ yarn translate`.
-## Starting
+:world_map: The front-end stores its own translations. See below how you can edit them easily.
 
 
-In development, you might want to copy `.env` into `.env.local` and set the environment variables. Then launch `$ yarn start`
+## :paintbrush: Customize your own application
 
-For production, see our [CI/CD configuration](https://github.com/MieuxVoter/continuous-integration).
+The separation between the front-end and the back-end makes it easy to customize your own application. Just install 
 
-## Testing
 
-Launch `$ yarn test`
+
+## :gear: Install options
+
+**Option one:** One-click deploy
+
+[![Deploy to Netlify](https://www.netlify.com/img/deploy/button.svg)](https://app.netlify.com/start/deploy?repository=https://github.com/MieuxVoter/mv-front-nextjs&utm_source=github)
+
+
+**Option two:** Manual clone
+
+1. Clone this repo: `git clone https://github.com/MieuxVoter/mv-front-nextjs.git`
+2. Navigate to the directory and install dependencies: `npm install` or `make`
+3. Start a local server: `npm run dev`  and open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+4. Make your changes
+5. Deploy your project.
+
+We advise for deploying the project to [Netlify](https://netlify.com), because we wrote the mail functions for the framework. Netlify parameters are written in `netlify.toml`.
+
+If you decide to deploy your project in another way, please fill a pull-request to guide futur users!
+
+## :incoming_envelope: Support for mail
+
+To add support for mail sending, you need to connect the application with a mailing service. For now, we only support [Mailgun](mailgun.com), which offer very competitive prices. You can fill an issue if you require another mailing service.
+
+To connect your application with Mailgun, you need to add the environment variables to your project:
+  
+- `MAILGUN_API_KEY`,
+- `MAILGUN_DOMAIN`,
+- `MAILGUN_URL`,
+- `FROM_EMAIL_ADDRESS`,
+- `CONTACT_TO_EMAIL_ADDRESS`.
+
+You can add the environment variables on an `.env` file or directly on [Netlify](https://docs.netlify.com/configure-builds/environment-variables/).
+
+
+## :world_map: I18N at heart
+
+You can directly modified the translation files in the folder `public/locales`.
+
+In case you want to add support for another language, you need as well to add it on `net-i18next.config.js` and on the `LanguageSelector` component.
