Pressing the home button or manually navigating back to ES-DE without exiting the game is equivalent to pressing "Alt+tab" on a desktop operating system, i.e. the game will still run. The difference from desktop operating systems is that Android pauses the game if you switch away from its window so it may seem like it has closed down, although it actually hasn't.

 Enforcement of a correct theme configuration is quite strict, and most errors will abort the theme loading, leading to an unthemed system. In each such situation the log output will be very clear of what happened, for instance:
 ```

 Note that an unthemed system means precisely that, the specific system where the error occured will be unthemed but not necessarily the entire theme. The latter can still happen if the error is global such as a missing variable used by all XML files or an error in a file included by all XML files.

 Error handling for missing files is handled a bit differently depending on whether the paths have been defined explicitly or via a variable. For explicitly defined paths a warning will be logged for element properties and an error will be triggered for include files. Here's an example of the latter case:
 
 ```
-Jan 28 17:32:29 Error:  ThemeData::parseIncludes(): "/home/myusername/.emulationstation/themes/mytheme-es-de/theme.xml" -> "./colors_dark.xml" not found (resolved to "/home/myusername/.emulationstation/themes/mytheme-es-de/colors_dark.xml")

 ```
 
 However, if a variable has been used to define the include file, only a debug message will be generated if the file is not found:
 ```
-Jan 28 17:34:03 Debug:  ThemeData::parseIncludes(): "/home/myusername/.emulationstation/themes/mytheme-es-de/theme.xml": Couldn't find file "./${system.theme}/colors.xml" which resolves to "/home/myusername/.emulationstation/themes/mytheme-es-de/amiga/colors.xml"

 It works essentially the same way for element path properties as for include files. This distinction between explicit values and variables makes it possible to create a theme configuration where both include files and files for fonts, images, videos etc. will be used if found, and if not found a fallback configuration can still be applied so the system will be themed.

+## Languages
+
+Multilingual support works very similarly to color schemes and font sizes in that it's a variable-based configuration. Due to this you can set any arbitrary property values you want for a certain language, such as different texts or different images and so on. The supported languages for use in themes are the same as for the overall application.
+
+Note that the word _language_ is not technically the correct term as it's rather _locales_ that are used within ES-DE. For instance the en_US and en_GB locales are both for the English language but rather variations for different countries (United States and United Kingdom). Still, as the term _language_ is colloquially used to describe locales in many applications and operating systems this is also used in ES-DE even if it's not entirely correct. The term _language_ is as such also used throughout this document.
+
+While it's possible to use the theme engine language support to set language-specific date formats this is generally discouraged as it's better to use the ISO 8601 (YYYY-MM-DD) standard instead. This is an international standard that makes sense to use in all countries in the world.
+
+The following languages are supported:
+
+| Language      | English name             | Native name              |
+| :------------ | :----------------------- | :----------------------- |

+| zh_CN         | Simplified Chinese       | 简体中文                 |
+
+These languages are currently getting translated and may be supported in the near future:
+
+| Language      | English name             | Native name              |
+| :------------ | :----------------------- | :----------------------- |

+| ar_EG         | Arabic                   | العربية                     |
+
+
+Note that the native name is what is shown inside the _UI Settings_ menu for the _Theme Language_ and _Application Language_ settings.
+
+You can find more information about locales/languages here:\
+https://simplelocalize.io/data/locales
+
+The languages a theme supports need to be declared in the `capabilities.xml` file using `<language>` tag pairs, such as the following example:
+
+```xml
+<!-- Theme capabilities for mytheme-es-de -->
+<themeCapabilities>
+    <themeName>My theme</themeName>
+
+    <language>en_US</language>
+    <language>es_ES</language>
+    <language>pt_PR</language>
+    <language>sv_SE</language>
+    <language>zh_CN</language>
+
+</themeCapabilities>
+```
+
+Although language support is optional for a theme, if you have declared at least one language then you have to include support for en_US as well. Attempting to skip an entry for this language will output an error message and the language configuration will not get loaded. The reason for this is that en_US is the default language for the ES-DE application so all themes have to support it, either implicitly (by not having any multilingual support) or explicitly by declaring it and providing localization for it.
+
+It's also possible to provide label translations for variants, color schemes and transitions, as displayed in the _UI Settings_ menu. This is done using the `language` attribute for these `label` entries, as in this example `capabilities.xml` file:
+
+```xml
+<themeCapabilities>
+    <themeName>My theme</themeName>
+
+    <language>en_US</language>
+    <language>sv_SE</language>
+
+    <colorScheme name="dark">
+        <label language="en_US">Dark</label>
+        <label language="sv_SE">Mörkt</label>
+    </colorScheme>
+
+    <variant name="withVideos">
+        <label language="en_US">Textlist with videos</label>
+        <label language="sv_SE">Textlista med video</label>
+        <selectable>true</selectable>
+        <override>
+            <trigger>noMedia</trigger>
+            <mediaType>miximage, screenshot, cover, video</mediaType>
+            <useVariant>noGameMedia</useVariant>
+        </override>
+    </variant>
+
+    <transitions name="instantAndSlide">
+        <label language="en_US">instant and slide</label>
+        <label language="sv_SE">direkt och glidande</label>
+        <selectable>true</selectable>
+        <systemToSystem>instant</systemToSystem>
+        <systemToGamelist>slide</systemToGamelist>
+        <gamelistToGamelist>instant</gamelistToGamelist>
+        <gamelistToSystem>slide</gamelistToSystem>
+        <startupToSystem>slide</startupToSystem>
+        <startupToGamelist>slide</startupToGamelist>
+    </transitions>
+</themeCapabilities>
+```
+
+Leaving out the `language` property will make ES-DE set the language to en_US.
+
+The actual language-specific values in the theme configuration are defined using variables, like the following example:
+
+```xml
+<theme>
+    <language name="en_US">
+        <variables>
+            <langLabelDeveloper>Developer</langLabelDeveloper>

+        </variables>
+    </language>
+    <language name="sv_SE">
+        <variables>
+            <langLabelDeveloper>Utvecklare</langLabelDeveloper>
+            <langLabelPublisher>Utgivare</langLabelPublisher>
+        </variables>
+    </language>
+
+    <view name="gamelist">

+            <text>${langLabelPublisher}</text>
+        </text>
+    </view>
+</theme>
+```
+
+It could also be a good idea to include the translations from a separate file:
+```xml
+<theme>
+    <include>./languages.xml</include>
+
+    <view name="gamelist">
+        <text name="labelDeveloper">
+            <pos>0.88 0.511</pos>

+            <text>${langLabelDeveloper}</text>
+        </text>
+        <text name="labelPublisher">
+            <pos>0.88 0.5935</pos>
+            <size>0.165 0.03</size>
+            <text>${langLabelPublisher}</text>
+        </text>
+    </view>
+</theme>
+```
+
+Including separate files per language is also supported but it's probably not a good idea as it will add a lot of unnecessary files to the theme:
+```xml
+<theme>
+    <language name="en_US">
+        <include>./lang-en_us.xml</include>
+    </language>
+    <language name="sv_SE">
+        <include>./lang-sv_se.xml</include>
+    </language>

+            <size>0.165 0.03</size>

 ## Aspect ratios
 
 The aspect ratio support works almost identically to the variants and color schemes with the main difference that the available aspect ratios are hardcoded into ES-DE. The theme can still decide which of the aspect ratios to support (or none at all in which case the theme aspect ratio is left undefined) but it can't create entirely new aspect ratio entries.

 For any given step, the configuration is parsed in the exact order that it's defined in the XML file. Be mindful of the logic described above as for instance defining variant-specific configuration above general configuration in the same XML file will still have that parsed afterwards.

 When there's an .mo file stored there it will override the bundled .mo file and ES-DE will use your local copy instead. This way you can easily test your own translations without having to build ES-DE from source code. Note that you need to restart ES-DE anytime you've compiled a new .mo file.

+## Theme translations
+
+In addition to what has been described above there is translation work needed for the actual themes as well. Some portion of the text displayed by the theme engine is part of the .po files, like the system view game counter and the custom collection summary, but most text is contained within each theme's configuration files.
+
+So to have a fully translated experience it's important to work together with the theme developers so they can incorporate full localization support into their themes. There is also an official metadata repository available for developers to use to easily include things like game system descriptions and various other information, and the goal is to have this fully translated to all languages as well.

+The [Haiku](https://www.haiku-os.org) port of ES-DE is currently experimental as the OS itself is experimental and has some issues. Still most functionality in ES-DE is working and there is support for a quite large number of systems and emulators. If you're interested in Haiku it's for sure worth trying it out.

+If the selected theme has multilingual support then you can select between its supported languages here. This setting is primarily intended for testing purposes and for theme developers, and should as such usually be left at _automatic_ which will select the same theme language as the overall application language (see the next setting below). Note that not all themes may support all languages that the ES-DE application supports.

 **Application language**
 
 Sets the language for the application user interface. If this option is set to _automatic_ then the language will be auto-detected, which means ES-DE will attempt to use whatever language has been selected in the operating system language settings. If there are no translations available in ES-DE for this precise language then a fallback will be done to the closest match, such as _Svenska_ instead of _Svenska (Finland)_. If no close match is available then ES-DE will revert to the default language which is _English (United States)_. It's also possible to explicitly select a supported language, which will override whatever has been set by the operating system. Note that the onboarding configurator for the Android release is unaffected by this setting. Also note that language auto-detection does not work on the Steam Deck when running in game mode, so there it's necessary to select a language explicitly. If you accidentally select a language you didn't intend to, then you can access the application language setting via the second menu entry from the top after opening the main menu, and then after entering this sub-menu by pressing the down button seven times.
