+# Multilingual Jekyll
+
+This repository aims to show how to get a minimal multilingual *Jekyll* website.
+
+It is based on the [**Making *Jekyll* multilingual**](https://www.sylvaindurand.org/making-jekyll-multilingual/) article, applied on the [Jekyll default theme](https://github.com/jglovier/jekyll-new).
+
+You can check the demo on [sylvaindurand.github.io/jekyll-multilingual/](https://sylvaindurand.github.io/jekyll-multilingual/).
+
+**Warning**: this repo is not maintained anymore by its author, but pull requests are still welcomed.
+
+
+## Make your website multilingual
+
+1. Have a look at the article [Making *Jekyll* multilingual](https://www.sylvaindurand.org/making-jekyll-multilingual/), which explains how things work
+2. Check the [diff for Jekyll 3.1.x](https://github.com/sylvaindurand/jekyll-multilingual/commit/111495e91e8986db21368e54a42188cdbbc44b6f) (older versions: [3.0.x](https://github.com/sylvaindurand/jekyll-multilingual/commit/b2da2a07c325a1b6e01f524dad6582f2daf70ccf), [2.5.x](https://github.com/sylvaindurand/jekyll-multilingual/commit/e0bed79df22d2d35a75d0906e2c9c2baeac44a73))
+3. Reproduce it on your website!
+
+
+## Create a multilingual website from stratch
+
+1. Still have a look at the article [Making *Jekyll* multilingual](https://www.sylvaindurand.org/making-jekyll-multilingual/), which explains how things work!
+2. Clone the repo: `git clone https://github.com/sylvaindurand/jekyll-multilingual.git`
+3. Open the folder: `cd jekyll-multilingual`
+4. Remove `Readme.md` and `jekyll-multilingual.gemspec`, which are useless outside this repository
+5. Build the website: `jekyll build`
+
+## Colophon
+
+After having written an article about having a multilingual *Jekyll* website, [sigul](https://talk.jekyllrb.com/t/a-vanilla-jekyll-theme-multilingual-with-no-plugins/) gave the idea to provide a minimal working example. Here we are!
+

+Cet article se situe dans le dossier `_posts`. Allez l'éditer, et générez votre site à nouveau pour voir les modifications. Vous pouvez générer le site de différentes façons, mais le plus efficace est de lancer la commande `jekyll serve`, qui crée un serveur web et génère automatiquement votre site à chaque fois qu'un fichier est modifié.
+
+Pour ajouter un autre article, créez un nouveau fichier dans le dossier `_posts` dont le nom contient la date de la façon suivante : `AAAA-MM-JJ-nom-de-l-article.ext` et placez-y l'entête.  includes the necessary front matter. Regardez le code source de cet article pour avoir une bonne idée de la façon dont cela fonctionne.
+
+Jekyll permet aussi d'intégrer des extraits de code :
+
+{% highlight ruby %}
+def print_hi(name)
+  puts "Bonjour, #{name}"
+end
+print_hi('Tom')
+#=> affiche 'Bonjour, Tom' sur STDOUT.
+{% endhighlight %}
+
+Jetez un coup d'oeil à la [documentation de Jekyll][jekyll-docs] pour en savoir plus sur ce qu'il vous est possible de faire avec Jekyll. Tous les bugs et demandes de fonctionnalités doivent être envoyés sous forme de requête sur [GitHub][jekyll-gh]. Si vous avez des questions, allez les poser sur le [fil d'aide de Jekyll][jekyll-talk].

+You’ll find this post in your `_posts` directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run `jekyll serve`, which launches a web server and auto-regenerates your site when a file is updated.
+
+To add new posts, simply add a file in the `_posts` directory that follows the convention `YYYY-MM-DD-name-of-post.ext` and includes the necessary front matter. Take a look at the source for this post to get an idea about how it works.
+
+Jekyll also offers powerful support for code snippets:
+
+{% highlight ruby %}
+def print_hi(name)
+  puts "Hi, #{name}"
+end
+print_hi('Tom')
+#=> prints 'Hi, Tom' to STDOUT.
+{% endhighlight %}
+
+Check out the [Jekyll docs][jekyll-docs] for more info on how to get the most out of Jekyll. File all bugs/feature requests at [Jekyll’s GitHub repo][jekyll-gh]. If you have questions, you can ask them on [Jekyll Talk][jekyll-talk].
