+
+HMCL provides localization support for multiple languages.
+
+This document describes HMCL's support status for these languages and provides a guide for contributors who want to help with HMCL localization.
+
+## Supported languages
+
+Currently, HMCL supports the following languages:

+<summary>About Language Tags</summary>
+
+HMCL uses language tags that conform to the IETF BCP 47 standard.
+
+When choosing language tags, we follow these principles:
+
+1. For languages defined in the ISO 639 standard, if a tag has already been registered in the [IANA Language Subtag Registry](https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry),
+   we always use the registered tag.
+
+   For example, for English, we use `en` instead of `eng` as the language code.
+
+2. For non-standard languages defined by Minecraft, the code defined in the language file's `language.code` should be preferred over the game language file's name.
+
+   This is because Minecraft sometimes uses real-world country/region codes to represent joke languages 
+   (for example, Pirate English uses the language file `en_pt`, but `PT` is actually the country code for Portugal).
+
+   For example, for Upside down English, we use `en-Qabs` as the language code instead of `en-UD`.
+
+</details>
+
+<details>
+<summary>About Localization Keys and File Suffixes</summary>
+
+Localization file suffixes and keys are used to name [localization resources](#localization-resources).
+
+Generally, the localization key is the language code for the resource, and the localization file suffix is obtained by replacing `-` with `_` in the language code and adding a leading underscore.
+
+As a special case, for default resources, the localization key is `default` and the file suffix is empty.
+
+Due to the existence of the [resource fallback mechanism](#resource-fallback-mechanism),
+if there is no resource that exactly matches the current locale, 
+HMCL will derive a search list from the current language tag and search for resources in order.
+
+We recommend always providing a default resource (with the `default` key and empty file suffix) when providing localization resources,
+to ensure all users can load resources properly.
+
+We also recommend using broader language tags for localization resources whenever possible,
+so users are less likely to fall back to the default resource.
+
+For example, if you provide a Simplified Chinese localization resource, 
+we recommend using `zh` as the localization key instead of the more specific `zh-Hans`,
+so it will apply to all Chinese users and avoid falling back to the default resource for them.
+
+If you want to provide both Simplified and Traditional Chinese resources, 
+it is recommended to use the broader `zh` as the key for the resource with more users (as the default Chinese resource),
+and use the more specific `zh-Hans`/`zh-Hant` as the key for the resource with fewer users.
+
+</details>
+
+HMCL requires all pull requests that update documentation and localization resources to also update the resources
+for all **primary** supported languages.
+If the PR author is not familiar with the relevant languages, they can request translation help in the comments,
+and maintainers will help translate these texts before merging the PR.
+
+For **secondary** supported languages, we cannot guarantee that these localization resources will always be updated in sync.
+We need collaborators who are proficient in these languages to help with maintenance.
+
+We will record volunteers willing to help maintain these language resources in the documentation.
+If contributors want to have new localization texts translated into these languages in a timely manner,
+they can @ these volunteers in the PR for help.
+
+If you are willing to help maintain localization resources for any language, please open a PR
+and add your GitHub username to the volunteer list above.
+We greatly appreciate your help.
+
+## Adding Support for a New Language
+
+HMCL welcomes anyone to participate in translation and contribution. 
+However, maintaining translations for more languages requires more maintenance effort, so we have some requirements for newly added languages.
+Please confirm the following requirements before contributing:
+
+- We prioritize [languages officially supported by Minecraft](https://minecraft.wiki/w/Language).
+
+  Unless there are special reasons, we do not provide support for languages not yet supported by Minecraft.
+- We hope to provide long-term maintenance support for all languages.
+
+  Since the maintainers of this project are proficient in only a limited number of languages, 
+  to avoid support for new languages quickly becoming outdated due to lack of maintainers,
+  we hope to find people proficient in the language to help us maintain the newly added localization files in the long term.
+  If there may be a lack of long-term maintainers, we will be more cautious about adding support for that language.
+
+We recommend that contributors submit a [feature request](https://github.com/HMCL-dev/HMCL/issues/new?template=feature.yml) before providing a new language translation,
+discuss with other contributors first, and determine the future maintenance plan before starting the translation work.
+
+### Getting Started with Translation
+
+If you want to add support for a new language to HMCL, please start by translating [`I18N.properties`](../HMCL/src/main/resources/assets/lang/I18N.properties).
+The vast majority of HMCL's texts are in this file, and translating it will translate the entire interface.
+
+This is a Java Properties file, which is very simple in format.
+Before translating, please read the introduction to this format: [Properties file](https://en.wikipedia.org/wiki/.properties).
+
+As the first step of translation, please look up the two- or three-letter language tag for your language in [this table](https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry).
+For example, the language tag for English is `en`.
+
+After determining the language tag, please create a file named `I18N_<localization file suffix>.properties` (e.g., `I18N_en.properties`) next to the [`I18N.properties` file](../HMCL/src/main/resources/assets/lang).
+Then you can start translating in this file.
+
+The `I18N.properties` file follows the [resource fallback mechanism](#resource-fallback-mechanism) to look up missing translations.
+That is, you can translate entry by entry, and any untranslated entries will automatically fall back to English.
+
+After translating part of the file, you can [build HMCL yourself](./README.md#compilation), 
+and your translations will be included in the compiled HMCL.
+If your computer's default environment is not the target language,
+you can set the environment variable `HMCL_LANGUAGE` to the language tag you just found from the table,
+and HMCL will automatically switch to that language.
+
+At this point, you can push the file to GitHub and submit a PR to HMCL.
+The maintainers of HMCL will complete the remaining steps for you.
+
+## Localization Resources
+
+All documentation and localization resource files follow the naming rule `<resource name><localization file suffix>.<extension>`.
+
+For example, for `README.md`, the localized versions in different languages are named as follows:
+
+- English: `README.md`
+- Chinese (Simplified): `README_zh.md`
+- Chinese (Traditional): `README_zh_Hant.md`
+- Chinese (Classical): `README_lzh.md`
+
+In addition to localized files, HMCL also supports localizing certain text fields in JSON. Localized text in JSON uses the following format:
+
+```json5
+{
+    "<Localization Key 1>": "<Localized Text 1>",
+    "<Localization Key 2>": "<Localized Text 2>",
+    // ...
+    "<Localization Key N>": "<Localized Text N>"
+}
+```
+
+For example, for the following text field:
+
+```json
+{
+    "meow": "Meow"
+}
+```
+
+It can be rewritten as localized text:
+
+```json
+{
+    "meow": {
+        "default": "Meow",
+        "zh": "喵呜",
+        "zh-Hant": "喵嗚"
+    }
+}
+```
+
+## Resource Fallback Mechanism
+
+For missing resources in a certain language, HMCL supports a resource fallback mechanism,
+which derives a search list based on different language tags and searches for resources in order according to this list.
+
+Before searching, we first refine the language tag through the following steps.
+
+1. Normalize Language Codes
+
+   If the language code subtag in the current language tag is not registered in the IANA Language Subtag Registry, 
+   HMCL will try to map it to a registered tag.
+
+   For example, HMCL will replace the language code `eng` with `en`.
+
+2. Map Macrolanguages to Individual Languages
+
+   If the current language code is an [ISO 639 macrolanguage](https://en.wikipedia.org/wiki/ISO_639_macrolanguage), 
+   and the macrolanguage usually refers to a specific individual language, HMCL will replace it with that individual language.
+
+   For example, `zh` (Chinese) usually actually refers to `cmn` (Mandarin), so we replace the language code `zh` with `cmn`.
+
+3. Derive Script
+
+   If the current language tag does not specify a script, HMCL will try to derive the script according to the following rules in order:
+
+    1. If the current language tag specifies a variant, and the variant is registered in the IANA Language Subtag Registry, 
+       and all its `Prefix` entries in the registry contain the same script, then set the current script to that script.
+
+       For example, if the current variant is `pinyin` (Chinese Pinyin), the script will be set to `Latn` (Latin).
+
+    2. If the current language code is assigned a `Suppress-Script` in the IANA Language Subtag Registry, set the current script to that script.
+
+       For example, if the current language code is `en` (English), the script will be set to `Latn` (Latin); 
+       if the code is `ru` (Russian), the script will be set to `Cyrl` (Cyrillic).
+
+    3. If the current language code is `lzh` (Classical Chinese), set the script to `Hant` (Traditional Chinese Characters).
+
+    4. If the current language code is `zh` or a sublanguage of `zh`, check if the current region code is one of `TW`, `HK`, or `MO`. 
+       If true, set the script to `Hant` (Traditional Chinese Characters);
+       otherwise, set it to `Hans` (Simplified Chinese Characters).
+
+After refining the language code, HMCL will derive a list of language tags based on this language tag.
+
+For example, for the language tag `en-US`, HMCL will refine it to `en-Latn-US` and derive the following search list:
+
+1. `en-Latn-US`
+2. `en-Latn`
+3. `en-US`
+4. `en`
+5. `und`
+
+For the language tag `zh-CN`, HMCL will refine it to `cmn-Hans-CN` and derive the following search list:
+
+1. `cmn-Hans-CN`
+2. `cmn-Hans`
+3. `cmn-CN`
+4. `cmn`
+5. `zh-Hans-CN`
+6. `zh-Hans`
+7. `zh-CN`
+8. `zh`
+9. `und`
+
+For resources that can be merged (such as `.properties` files), 
+HMCL will merge resources according to the priority of this list; for resources that are difficult to merge (such as font files), 
+HMCL will load the highest-priority resource found in this list.
+
+If the current language uses a three-letter ISO 639 code, but there is also a corresponding two-letter code, 
+HMCL will map it to the two-letter code before searching for resources.
+
+For example, if the current environment's language tag is `eng-US`, 
+HMCL will map it to `en-US` and then search for localization resources according to the above rules.
+
+### Additional Rules for Chinese
+
+HMCL always adds `zh-CN` to the search list for all Chinese environments, 
+and adds `zh-TW` to the search list for all Traditional Chinese environments.
+
+Below are the localization resource search lists for several common Chinese environments.
+
+- `zh-CN`:
+    1. `cmn-Hans-CN`
+    2. `cmn-Hans`
+    3. `cmn-CN`
+    4. `cmn`
+    5. `zh-Hans-CN`
+    6. `zh-Hans`
+    7. `zh-CN`
+    8. `zh`
+    9. `und`
+- `zh-SG`:
+    1. `cmn-Hans-SG`
+    2. `cmn-Hans`
+    3. `cmn-SG`
+    4. `cmn`
+    5. `zh-Hans-SG`
+    6. `zh-Hans`
+    7. `zh-SG`
+    8. `zh-CN`
+    9. `zh`
+    10. `und`
+- `zh-TW`:
+    1. `zh-Hant-TW`
+    2. `zh-Hant`
+    3. `zh-TW`
+    4. `zh`
+    5. `zh-CN`
+    6. `und`
+- `zh-HK`:
+    1. `cmn-Hant-HK`
+    2. `cmn-Hant`
+    3. `cmn-HK`
+    4. `cmn`
+    5. `zh-Hant-HK`
+    6. `zh-Hant`
+    7. `zh-HK`
+    8. `zh-TW`
+    9. `zh`
+    10. `zh-CN`
+    11. `und`
+- `lzh`:
+    1. `lzh-Hant`
+    2. `lzh`
+    3. `zh-Hant`
+    4. `zh-TW`
+    5. `zh`
+    6. `zh-CN`
+    7. `und`

+## Automatic Synchronization of Documentation Content
+
+<!-- #BEGIN BLOCK -->
+<!-- #PROPERTY PROCESS_LINK=false -->
+To simplify documentation maintenance, HMCL uses a macro mechanism to automatically maintain parts of the documentation content.
+Run the following command in the terminal:
+
+```bash
+./gradlew updateDocuments
+```
+
+This will automatically update all documentation content.
+
+For example, to create links for switching between different language versions of the same document, 
+add the following content under the document title:
+
+```markdown
+<!-- #BEGIN LANGUAGE_SWITCHER -->
+<!-- #END LANGUAGE_SWITCHER -->
+```
+
+After running `./gradlew updateDocuments`, these two lines will be automatically replaced with language switcher links like the following:
+
+```markdown
+**English** (**Standard**, [uʍoᗡ ǝpᴉsd∩](README_en_Qabs.md)) | 中文 ([简体](README_zh.md), [繁體](README_zh_Hant.md), [文言](README_lzh.md)) | [日本語](README_ja.md) | [español](README_es.md) | [русский](README_ru.md) | [українська](README_uk.md)

+在搜索前，我们会先通过以下步骤对语言标签进行细化推导。

-1. `en-US`
+1. 归一化语言代码
+
+   如果当前语言标签中的语言代码子标签未在 IANA 语言子标签注册表中进行注册，HMCL 会先尝试将其映射为注册表中已注册的标签。
+
+   例如，HMCL会将语言代码 `eng` 替换为 `en`。
+
+2. 映射宏语言至子语言
+
+   如果当前语言代码是一个 [ISO 639 宏语言](https://en.wikipedia.org/wiki/ISO_639_macrolanguage)，
+   且该宏语言通常指代某个个体语言，HMCL 会将其替换为该个体语言。

+3. 推导拼写脚本
+

+
+   1. 如果当前语言标签指定了语言变体，该语言变体已在 IANA 语言子标签注册表中，
+      且注册表中其所有 `Prefix` 都包含相同的拼写脚本，则将当前拼写脚本指定为该脚本。
+
+      例如，如果当前语言变体为 `pinyin` (汉语拼音)，则当前拼写脚本会被指定为 `Latn` (拉丁文)。
+

+
+      例如，如果当前语言代码为 `en` (英语)，则当前拼写脚本会被指定为 `Latn` (拉丁文);
+      如果当前语言代码为 `ru` (俄语)，则当前拼写脚本会被指定为 `Cyrl` (西里尔文)。
+
+   3. 如果当前语言代码是 `lzh` (文言)，则将当前拼写脚本指定为 `Hant` (繁体汉字)。
+
+   4. 如果当前语言代码是 `zh` 或 `zh` 的子语言，则检查当前国家/地区代码是否为 `TW`、`HK`、`MO` 之一。
+      如果结果为真，则将当前拼写脚本指定为 `Hant` (繁体汉字)；否则将当前拼写脚本指定为 `Hans` (简体汉字)。
+
+在对语言代码细化推导完成后，HMCL 会开始根据此语言标签推导出一个语言标签列表。
+
+例如，对于语言标签 `en-US`，HMCL 会将其细化为 `en-Latn-US`，并据此推导出以下搜索列表:

 ### 对于中文的额外规则

-对于中文 (以及其子语言标签，例如文言文 (`lzh`)、普通话 (`cmn`)、粤语 (`yue`) 等等)，HMCL 有着额外的支持。

-对于语言为 `lzh` 或地区为 `TW`、`HK`、`MO` 的情况，默认书写脚本为繁体中文 (`Hant`)；
-而对于其他语言和地区，默认书写脚本为简体中文 (`Hans`)。
