 Here are a few other miscellaneous settings you can configure from the home page of the **Admin Panel**.
 
 ### Site Name
+
 How you’d like to refer to this instance of Metabase.
 
 ### Site URL
+
 The base URL of this Metabase instance. The base URL is used in emails to allow users to click through to their specific instance. Make sure to include http:// or https:// to make sure it’s reachable.
 
 ### Email Address for Help Requests
-This email address will be displayed in various messages throughout Metabase when users encounter a scenario where they need assistance from an admin, such as a password reset request.

-*Setting the default timezone will not change the timezone of any data in your database*. If the underlying times in your database aren't assigned to a timezone, Metabase will use the report timezone as the default timezone.

+Metabase has been translated into a variety of languages, and this setting allows you to configure the language to be used for external Metabase communications, such as emails and pulses. There is not currently a setting to set the language in the Metabase interface for all of your users; instead, Metabase relies on each user's browser language to determine which language should be used, provided Metabase supports that translation.

 By default, Metabase attempts to make field and table names more readable by changing things like `somehorriblename` to `Some Horrible Name`. This does not work well for languages other than English, or for fields that have lots of abbreviations or codes in them. If you'd like to turn this setting off, you can do so from the Admin Panel under Settings > General > Friendly Table and Field Names.

 # What languages can be used with Metabase?
 
-Thanks to our amazing user community, Metabase has been translated into a variety of languages. Due to the nature of how we collect translations (more on that in a minute), available languages may be added or removed during major releases, depending on the translation coverage. 
-
-The available languages as of the 0.33 release are:
-
-* Catalan
-* Dutch
-* French
-* German
-* Italian
-* Japanese
-* Norwegian Bokmål
-* Polish
-* Portuguese
-* Spanish
-* Russian
-* Turkish
-* Ukranian
-* Vietnamese
-
-Metabase translations are collected via a [POEditor project](https://poeditor.com/join/project/ynjQmwSsGh). In order for a language to be added to Metabase as a supported language, it has to achieve 100% translation. If a language falls below 90% translation, we will remove it from Metabase until it returns to being 100% translated. We make sure to alert the POEditor community a few weeks ahead of a major release if there are languages in danger of being removed from Metabase, and the language coverage can be viewed on the POEditor project page at any time.
-
-Note that while we will only remove languages during major releases, we will add them back in during minor releases - so it's always a good time to jump in and start translating!
+Thanks to our amazing user community, Metabase has been translated into a variety of languages. Due to the nature of how we collect translations (more on that in a minute), available languages may be added or removed during major releases, depending on the translation coverage.
+
+## Currently available languages
+
+The available languages as of the 0.35 release are:
+
+- Catalan
+- Chinese, simplified
+- Chinese, traditional
+- Dutch
+- French
+- German
+- Italian
+- Japanese
+- Persian
+- Polish
+- Portuguese
+- Spanish
+- Russian
+- Slovak
+
+Some translations were previously available in Metabase, but have been removed as they are no longer complete:
+
+- Norwegian Bokmål
+- Turkish
+- Ukrainian
+- Vietnamese
+
+## Policy for adding and removing translations
+
+The community contributes to Metabase translations on our [POEditor project](https://poeditor.com/join/project/ynjQmwSsGh). If you're a fan of Metabase and would like to see it made available in a language you're fluent in, we'd love your help!
+
+For new translations to be added to Metabase they must reach 100%. Once they have, we'll add them in the next major or minor release of Metabase. All _existing_ translations in Metabase _must stay at 100%_ to continue being included in the next _major_ version of Metabase. This is to ensure that no one encounters a confusing mishmash of English and another language when using Metabase.
+
+We understand that this is a high bar, so we commit to making sure that before each major release, any additions or changes to text in the product will be completed at least 10 calendar days before the final release ships, at which point we notify all translators that a new release will be happening soon.
+
+Note that while we will only remove languages in major releases, we will add them back in for minor releases — so it's always a good time to jump in and start translating!
