 ## Translate Your Content
 
-Translated articles are identified by the name of the content file.
+There are two ways to manage your content translation, both ensures each page is assigned a language and linked to its translations.
 
-### Examples of Translated Articles
+### Translation by filename
+
+Considering the following example:
 
 1. `/content/about.en.md`
 2. `/content/about.fr.md`
 
-In this example, the `about.md` will be assigned the configured `defaultContentLanguage`. 
+The first file is assigned the english language and linked to the second.
+The second file is assigned the french language and linked to the first.
 
-1. `/content/about.md`
-2. `/content/about.fr.md`
+Their language is __assigned__ according to the language code added as __suffix to the filename__. 
 
-This way, you can slowly start to translate your current content without having to rename everything. If left unspecified, the default value for `defaultContentLanguage` is `en`.
+By having the same **path and base filename**, the content pieces are __linked__ together as translated pages.
+{{< note >}}
 
-By having the same **directory and base filename**, the content pieces are linked together as translated pieces.
+If a file is missing any language code, it will be assigned the default language.
 
-You can also set the key used to link the translations explicitly in front matter:
+{{</ note >}}
+### Translation by content directory
+
+This system uses different content directories for each of the languages. Each language's content directory is set using the `contentDir` param.
+
+{{< code-toggle file="config" >}}
+
+languages:
+  en:
+    weight: 10
+    languageName: "English"
+    contentDir: "content/english"
+  nn:
+    weight: 20
+    languageName: "Français"
+    contentDir: "content/french"
+
+{{< /code-toggle >}}
+
+The value of `contentDir` can be any valid path, even absolute path references. The only restriction is that the content directories cannot overlap.
+
+Considering the following example in conjunction with the configuration above: 
+
+1. `/content/english/about.md`
+2. `/content/french/about.md`
+
+The first file is assigned the english language and is linked to the second.
+<br>The second file is assigned the french language and is linked to the first.
+
+Their language is __assigned__ according to the content directory they are __placed__ in.
+
+By having the same **path and basename** (relative to their language content directory), the content pieces are __linked__ together as translated pages.
+
+### Bypassing default linking.
+
+Any pages sharing the same `translationKey`  set in front matter will be linked as translated pages regardless of basename or location.
+
+Considering the following example:
+
+1. `/content/about-us.en.md`
+2. `/content/om.nn.md`
+3. `/content/presentation/a-propos.fr.md`
 
 ```yaml
-translationKey: "my-story"
+# set in all three pages
+translationKey: "about"
 ```
 
-If you need distinct URLs per language, you can set the slug in the non-default language file. For example, you can define a custom slug for a French translation in the front matter of `content/about.fr.md` as follows:
+By setting the `translationKey` front matter param to `about` in all three pages, they will be __linked__ as translated pages.
 
-```yaml
+
+### Localizing permalinks
+
+Because paths and filenames are used to handle linking, all translated pages, except for the language part, will be sharing the same url.
+
+To localize the URLs, the [`slug`]({{< ref "content-management/organization/index.md#slug" >}}) or [`url`]({{< ref "content-management/organization/index.md#url" >}}) front matter param can be set in any of the non-default language file. 
+
+For example, a french translation (`content/about.fr.md`) can have its own localized slug.
+
+{{< code-toggle >}}
+Title: A Propos
 slug: "a-propos"
+{{< /code-toggle >}}
 
-```
 
-At render, Hugo will build both `/about/` and `/a-propos/` as properly linked translated pages.
+At render, Hugo will build both `/about/` and `fr/a-propos/` while maintaning their translation linking.
+{{% note %}}
+If using `url`, remember to include the language part as well: `fr/compagnie/a-propos/`.
+{{%/ note %}}
 
-For merging of content from other languages (i.e. missing content translations), see [lang.Merge](/functions/lang.merge/).
+### Page Bundles
 
-## Link to Translated Content
+To avoid the burden of having to duplicate files, each Page Bundle inherits the resources of its linked translated pages' bundles except for the content files (markdown files, html files etc...).
+
+Therefore, from within a template, the page will have access to the files from all linked pages' bundles.
+
+If, across the linked bundles, two or more files share the same basenname, only one will be included and chosen as follows:
+
+* File from current language Bundle, if present.
+* First file found across bundles by order of language `Weight`.
+
+{{% note %}}
+
+Page Bundle's resources follow the same language assignement logic as content files, be it by filename (`image.jpg`, `image.fr.jpg`) or by directory (`english/about/header.jpg`, `french/about/header.jpg`).

+categories: ["Releases"]
+---
+
+	Hugo `0.42` adds **Theme Components**. This is a really powerful new way of building your Hugo sites with reusable components. This is both **Theme Composition** and **Theme Inheritance**.
+
+>Read more about Theme Components in the [Hugo Documentation](https://gohugo.io/themes/theme-components/).
+
+The feature above was implemented by [@bep](https://github.com/bep), the funny Norwegian, with great design help from the Hugo community. But that implementation would not have been possible without [Afero](https://github.com/spf13/afero), [Steve Francia's](https://github.com/spf13) virtual file system. Hugo is built on top of Afero and many other fast and solid Go projects, and if you look at the combined contribution log of the Hugo project and its many open source dependencies, the total amount of contributions is staggering. A big thank you to them all!
+
+This release represents **27 contributions by 7 contributors** to the main Hugo code base. [@bep](https://github.com/bep) leads the Hugo development with a significant amount of contributions, but also a big shoutout to [@onedrawingperday](https://github.com/onedrawingperday), [@anthonyfok](https://github.com/anthonyfok), and [@stefanneuhaus](https://github.com/stefanneuhaus) for their ongoing contributions.
+
+And a big thanks to [@digitalcraftsman](https://github.com/digitalcraftsman) for his relentless work on keeping the themes site in pristine condition and to [@kaushalmodi](https://github.com/kaushalmodi) for his great work on the documentation site.
+
+Many have also been busy writing and fixing the documentation in [hugoDocs](https://github.com/gohugoio/hugoDocs), 
+which has received **8 contributions by 5 contributors**. A special thanks to [@bep](https://github.com/bep), [@LorenzCK](https://github.com/LorenzCK), [@gavinwray](https://github.com/gavinwray), and [@deyton](https://github.com/deyton) for their work on the documentation site.

+* 444+ [contributors](https://github.com/gohugoio/hugo/graphs/contributors)
+* 235+ [themes](http://themes.gohugo.io/)
+
+## Notes
+* The `speakerdeck` shortcode is removed. It didn't work properly, so is isn't expected to be in wide use. If you use it, you will get a build error. You will either have to remove its usage or add a `speakerdeck` shortcode to your own project or theme.
+* We have now virtualized the filesystems for project and theme files. This makes everything simpler, faster and more powerful. But it also means that template lookups on the form `{{ template “theme/partials/pagination.html” . }}` will not work anymore. That syntax has never been documented, so it's not expected to be in wide use. `{{ partial "pagination.html" . }}` will give you the most specific version of that partial.

+
+_By Bjørn Erik Pedersen ([@bepsays](https://twitter.com/bepsays) / [@bep](https://github.com/bep)), Hugo Lead_
+
+**Five years ago today, [Steve Francia](https://github.com/spf13/) made his [first commit](https://github.com/gohugoio/hugo/commit/50a1d6f3f155ab837310e00ffb309a9199773c73
+) on the Hugo project: "Hugo: A Fast and Flexible Static Site Generator built with love by spf13 in GoLang".**
+
+Steve was writing that on a train commute to New York. I'm writing this article running Hugo `v0.43-DEV`, the preview version of the next Hugo release. The release is scheduled for Monday and adds a powerful [assets pipeline](https://github.com/gohugoio/hugo/issues/4854#issue-333062459), with SCSS/SASS support, assets minification, fingerprinting/subresource integrity, ad-hoc image processing and much more. 
+
+**I cannot remember the last time I was this excited about a Hugo release. "Game changer" may be too strong, but it makes for a really nice integrated website design-workflow that, with Hugo's build speed, is hard to beat.**
+
+{{< imgproc sunset Fill "600x300" >}}
+Fetch and scale an image in the upcoming Hugo 0.43.
+{{< /imgproc >}}
+
+But that is a release for Monday. Now is a time to look at the current status of Hugo after the first five years.
+
+## Hugo in Numbers
+
+According to [BuiltWith](https://trends.builtwith.com/cms/Hugo), more than 29 000 live websites are built with Hugo. Of those, 390 are in the top 1 million. Wappalyzer [reports](https://www.wappalyzer.com/categories/static-site-generator) that Hugo serves almost 50% of the static sites.
+
+Hugo is big in the [public sector](https://discourse.gohugo.io/t/hugo-in-public-administration/8792), with the US Government as a prominent user. Some examples are [vote.gov](https://vote.gov/) and [digital.gov](https://digital.gov/).
+
+[Smashing Magazine](https://www.smashingmagazine.com/) is a big and very popular Hugo site. It is [reported](https://discourse.gohugo.io/t/smashing-magazine-s-redesign-powered-by-hugo-jamstack/5826/7) that they build their complex site with 7500 content pages in 13 seconds.
+
+Some other example sites are [kubernetes.io](https://kubernetes.io/), [letsencrypt.org](https://gohugo.io/showcase/letsencrypt/), [support.1password.com](http://gohugo.io/showcase/1password-support/), [netlify.com](https://www.netlify.com), [litecoin.org](https://litecoin.org/), and [forestry.io](https://forestry.io/).
+
+
+{{< imgproc graph-stars Fit "600x400" >}}
+Number of GitHub stars in relation to the Hugo release dates.
+{{< /imgproc >}}
+
+More numbers:
+
+* 26800+ [stars](https://github.com/gohugoio/hugo/stargazers) on GitHub. 
+* 444+ [contributors](https://github.com/gohugoio/hugo/graphs/contributors) to the Hugo source repository, 654+ to [Hugo Docs](https://github.com/gohugoio/hugoDocs/graphs/contributors). [@bep](https://github.com/bep) is the most active with around 70% of the current code base (line count).
+* 235+ [themes](https://themes.gohugo.io/)
+* 50% increase in the number of user sessions on the [gohugo.io](https://gohugo.io/) web sites the last 12 months.[^2]
+* Hugo build release binaries for [a myriad](https://github.com/gohugoio/hugo/releases/tag/v0.42.2) of platforms. And since it can also be installed from Chocolatey on Windows, Brew on MacOs, Snap on Linux and `apt-get` on Debian/Ubuntu, it is impossible to give accurate download numbers. But the number is not small.
+
+## Hugo Next
+
+We're not finished with Hugo, but Hugo `0.43` very nicely wraps up the first five years. It started out as a small and fast static site generator. It is now [even faster](https://forestry.io/blog/hugo-vs-jekyll-benchmark/), and now so loaded with features that it has grown out of being just a "static site generator". It is a _framework for building websites_.
+
+My interest in Hugo started on the Sunday when I moved my blog, [bepsays.com](https://bepsays.com/en/), twice. The second static generator choice of that day, Hugo, was a good match. I remember Steve being very enthusiastic about getting patches with fixes and enhancements, and I was eventually taken over by the simplicity and power of Go, the programming language, and started to implement lots of new features.
+
+My goal with all of this, if there is one, is to get a single binary with native and really fast implementations of the complete stack I need for web development and content editing. The single binary takes most of the pain out of installation and upgrades (if you stick with the same binary, it will continue to just work for decades).
+
+**With 0.43, we are almost there.** With that release, it should be possible to set up a Hugo-only project without any additional tools (Gulp, WebPack) for all aspects of website building. There will still be situations where those tools will still be needed, of course, but we will continue to fill the gaps in the feature set. 
+
+Hugo has stuck with the sub-zero versions to signal active development, with a new main release every 5-6 weeks. But we take stability very seriously (breaking things add lots of support work, we don't like that) and most site upgrades are [smooth](https://twitter.com/tmmx/status/1006288444459503616). But we are closing in on the first major stable version.
+
+
+### The Road to 1.0
+
+We have some more technical tasks that needs to be done (there is ongoing work to get the page quries into a more consistent state, also a simpler `.GetPage` method), but also some cool new functionality. The following roadmap is taken from memory, and may not be complete, but should be a good indication of what's ahead.
+
+Pages from "other data sources"
+: Currently, in addition to Hugo's list pages, every URL must be backed by a content file (Markdown, HTML etc.). This covers most use cases, but we need a flexible way to generate pages from other data sources. Think product catalogues and similar.
+
+Upgrade Blackfriday to v2
+: [Blackfriday](https://github.com/russross/blackfriday) is the main content renderer in Hugo. It has been rewritten to a more flexible architecture, which should allow us to fix some of the current shortcomings.
+
+We should be able to create a better and easier-to-use data structure from the rendered content: Summary, the content after the summary, being able to range over the footnotes and the ToC. Having ToC as a proper data structure also open up a few other potential uses; using it as an index in [Related Content](https://gohugo.io/content-management/related/) would be one example.
+
+This should also enable us to _do more_ with [Custom Output Formats](/templates/output-formats). It is already very powerful. GettyPubs are using it in [Quire](https://github.com/gettypubs/quire) to build [beautiful multi-platform publications](http://www.getty.edu/publications/digital/digitalpubs.html). But it can be improved. For rendering of content files, you are currently restricted to HTML. It would be great if we could configure alternative renderers per output format, such as LaTeX and EPUB.
+
+Related to this is also to add a configurable "Markdown URL rewriter", which should make more portable URLs in Markdown, e.g. image links that work both when viewed on GitHub and your published site. 
+
+### The Road to the Future
+
+These are the items that first comes to mind if you ask me to think even further ahead:
+
+Dependency manager for Theme Components
+: In Hugo `0.42` we added [Theme Components](/themes/theme-components/) and Theme Inheritance. With SCSS support in Hugo `0.43`, which also follows the same project/themes precedence order (add `_variables.scss` to your project, configure SASS colour variables in `config.toml`), we have a solid foundation for creating easy to use and extensible themes. But we are missing some infrastructure around this. We have a site with 235+ [themes](https://themes.gohugo.io/)[^themes] listed, but you currently need to do some added work to get the theme up and running for your site. In the Go world, we don't have NPM to use, which is a curse and a blessing, but I have some ideas about building a simple dependency manager into Hugo, modelled after how Go is doing it (`hugo install`). You should be able to configure what theme and theme components you want to use, and Hugo should handle the installation of the correct versions. This should make it easier for the user, but it would also enable community driven and even commercial "theme stores".

+{{< /imgproc >}}
+
+
+The "New York Times on Hugo" Use Case
+: There are recurring questions on the support forum from [really big sites](https://discourse.gohugo.io/t/transition-2m-posts-from-wordpress-to-hugo/12704) that want to move to Hugo. There are many [good reasons](https://www.netlify.com/blog/2016/05/18/9-reasons-your-site-should-be-static/) why they want this (security, cost-saving, EU regulations etc.). And while there have been reports about companies building 600 000 pages with Hugo on very powerful hardware, we will have to rethink the build model to make this usable. Keywords are: streaming builds, segmented builds, partial rebuilds. There are other site generators also talking about this. It should be possible, and my instinct tells me that it should be easier to do when your starting point is "really fast". But this is not a small weekend project for me, and I have already talked to several companies about sponsoring this.
+
+Plugins
+: A Theme Component could also be called a plugin. But there are several potential plugin hooks into Hugo's build pipeline: Resource transformations, content rendering etc. We will eventually get there, but we should do it without giving up too much of the Hugo speed and simplicity.
+
+
+## Thanks
+
+So, thanks to everyone who have contributed to getting Hugo where it is today. It is hard to single out individuals, but a big shout-out to all the Hugo experts and moderators helping out making the [discourse.gohugo.io](https://discourse.gohugo.io/) a very active and possibly one of the best support forums out there.
+
+And the last shout-out goes to two maintainers who have been there more or less from the start. [@digitalcraftsman](https://github.com/digitalcraftsman/) has been doing a fantastic job keeping the fast growing theme site and [repository](https://github.com/gohugoio/hugoThemes) in pristine condition. I have it on my watch list, but that is just out of curiosity. There are lots of activity, but it runs as clock work. [Anthony Fok](https://github.com/anthonyfok) has contributed with a variety of things but is most notable as the Linux expert on the team. He manages the Debian build and is the one to thank for up-to-date binaries on Debian and Ubuntu.

-## Theme Components
+## Theme Folders
 
-A theme consists of templates and static assets such as javascript and css files. Themes can also provide [archetypes][], which are archetypal content types used by the `hugo new` command to scaffold new content files with preconfigured front matter.
+A theme component can provide files in one or more of the following standard Hugo folders:
+
+layouts
+: Templates used to render content in Hugo. Also see [Templates Lookup Order](/templates/lookup-order/).
+
+static
+: Static files, such as logos, CSS and JavaScript.
+
+i18n
+: Language bundles.
+
+data
+: Data files.
+
+archetypes
+: Content templates used in `hugo new`.
+
+
+## Theme Configuration File
+
+A theme component can also provide its own [Configuration File](/getting-started/configuration/), e.g. `config.toml`. There are some restrictions to what can be configured in a theme component, and it is not possible to overwrite settings in the project.
+
+The following settings can be set:
+
+* `params` (global and per language)
+* `menu` (global and per language)
+* `outputformats` and `mediatypes`
+
+
+## Theme Description File
+
+In addition to the configuration file, a theme can also provide a `theme.toml` file that describes the theme, the author and origin etc. See [Add Your Hugo Theme to the Showcase](/contribute/themes/).
 
 
 {{% note "Use the Hugo Generator Tag" %}}
 The [`.Hugo.Generator`](/variables/hugo/) tag is included in all themes featured in the [Hugo Themes Showcase](http://themes.gohugo.io). We ask that you include the generator tag in all sites and themes you create with Hugo to help the core team track Hugo's usage and popularity.

-## Layouts
 
-Hugo is built around the concept that things should be as simple as possible.
-Fundamentally, website content is displayed in two different ways, a single
-piece of content and a list of content items. With Hugo, a theme layout starts
-with the defaults. As additional layouts are defined, they are used for the
-content type or section they apply to. This keeps layouts simple, but permits
-a large amount of flexibility.
-
-## Single Content
-
-The default single file layout is located at `layouts/_default/single.html`.
-
-## List of Contents
-
-The default list file layout is located at `layouts/_default/list.html`.
-
-## Partial Templates
-
-Theme creators should liberally use [partial templates](/templates/partials/)
-throughout their theme files. Not only is a good DRY practice to include shared
-code, but partials are a special template type that enables the themes end user
-to be able to overwrite just a small piece of a file or inject code into the
-theme from their local /layouts. These partial templates are perfect for easy
-injection into the theme with minimal maintenance to ensure future
-compatibility.
-
-## Static
-
-Everything in the static directory will be copied directly into the final site
-when rendered. No structure is provided here to enable complete freedom. It is
-common to organize the static content into:
-
-```
-/css
-/js
-/img
-```
-
-The actual structure is entirely up to you, the theme creator, on how you would like to organize your files.
-
-## Archetypes
-
-If your theme makes use of specific keys in the front matter, it is a good idea
-to provide an archetype for each content type you have. [Read more about archetypes][archetypes].

-## Override Static Files
-
-There are times where you want to include static assets that differ from versions of the same asset that ships with a theme.
-
-For example, a theme may use jQuery 1.8 in the following location:
-
-```
-/themes/<THEME>/static/js/jquery.min.js
-```
-
-You want to replace the version of jQuery that ships with the theme with the newer `jquery-3.1.1.js`. The easiest way to do this is to replace the file *with a file of the same name* in the same relative path in your project's root. Therefore, change `jquery-3.1.1.js` to `jquery.min.js` so that it is *identical* to the theme's version and place the file here:
-
-```
-/static/js/jquery.min.js
-```
-
-## Override Template Files
-
-Anytime Hugo looks for a matching template, it will first check the working directory before looking in the theme directory. If you would like to modify a template, simply create that template in your local `layouts` directory.
-
-The [template lookup order][lookup] explains the rules Hugo uses to determine which template to use for a given piece of content. Read and understand these rules carefully.
-
-This is especially helpful when the theme creator used [partial templates][partials]. These partial templates are perfect for easy injection into the theme with minimal maintenance to ensure future compatibility.
-
-For example:
-
-```
-/themes/<THEME>/layouts/_default/single.html
-```
-
-Would be overwritten by
-
-```
-/layouts/_default/single.html
-```
-
-{{% warning %}}
-This only works for templates that Hugo "knows about" (i.e., that follow its convention for folder structure and naming). If a theme imports template files in a creatively named directory, Hugo won’t know to look for the local `/layouts` first.
-{{% /warning %}}
-
-## Override Archetypes
-
-If the archetype that ships with the theme for a given content type (or all content types) doesn’t fit with how you are using the theme, feel free to copy it to your `/archetypes` directory and make modifications as you see fit.
-
-{{% warning "Beware of `layouts/_default`" %}}
-The `_default` directory is a very powerful force in Hugo, especially as it pertains to overwriting theme files. If a default file is located in the local [archetypes](/content-management/archetypes/) or layout directory (i.e., `archetypes/default.md` or `/layouts/_default/*.html`, respectively), it will override the file of the same name in the corresponding theme directory (i.e., `themes/<THEME>/archetypes/default.md` or `themes/<THEME>/layout/_defaults/*.html`, respectively).
-
-It is usually better to override specific files; i.e. rather than using `layouts/_default/*.html` in your working directory.

+---
+
+Since Hugo `0.42` a project can configure a theme as a composite of as many theme components you need:
+
+{{< code-toggle file="config">}}
+theme = ["my-shortcodes", "base-theme", "hyde"]
+{{< /code-toggle >}}
+
+
+You can even nest this, and have the theme component itself include theme components in its own `config.toml` (theme inheritance).[^1]
+
+The theme definition example above in `config.toml` creates a theme with 3 theme components with precedence from left to right.
+
+For any given file, data entry, etc., Hugo will look first in the project and then in `my-shortcode`, `base-theme`, and lastly `hyde`.
+
+Hugo uses two different algorithms to merge the filesystems, depending on the file type:
+
+* For `i18n` and `data` files, Hugo merges deeply using the translation id and data key inside the files.
+* For `static`, `layouts` (templates), and `archetypes` files, these are merged on file level. So the left-most file will be chosen.
+
+The name used in the `theme` definition above must match a folder in `/your-site/themes`, e.g. `/your-site/themes/my-shortcodes`. There are plans to improve on this and get a URL scheme so this can be resolved automatically.
+
+Also note that a component that is part of a theme can have its own configuration file, e.g. `config.toml`. There are currently some restrictions to what a theme component can configure:
+
+* `params` (global and per language)
+* `menu` (global and per language)
+* `outputformats` and `mediatypes`
+
+The same rules apply here: The left-most param/menu etc. with the same ID will win. There are some hidden and experimental namespace support in the above, which we will work to improve in the future, but theme authors are encouraged to create their own namespaces to avoid naming conflicts.
+
+
+[^1]: Including theme components in the themes is currently not supported for themes hosted on [The Hugo Themes Site](https://themes.gohugo.io/), but can be really useful if you want to create your own theme based on a theme you find on that site.
