# 12.2.2. I18N

We only had documentation in Japanese. We start to support I18N documentation by gettext based Sphinx I18N feature. We’ll use English as base language and translate English into other languages such as Japanese. We’ll put all documentations into doc/source/ and process them by Sphinx.

But we still use Japanese in doc/source/ for now. We need to translate Japanese documentation in doc/source/ into English. We welcome to you help us by translating documentation.

## 12.2.2.1. Translation flow

After doc/source/*.txt are updated, we can start translation.

Here is a translation flow:

1. Install Sphinx, if it is not installed.

2. Clone Groonga repository.

3. Update .po files.

4. Edit .po files.

5. Generate HTML files.

6. Confirm HTML output.

7. Repeat 2.-4. until you get good result.

8. Send your works to us!

Here are command lines to do the above flow. Following sections describes details.

    # Please fork https://github.com/groonga/groonga on GitHub
    % git clone https://github.com/${YOUR_GITHUB_ACCOUNT}/groonga.git
    % ./autogen.sh
    % ./configure --enable-document
    % cd doc/locale/${LANGUAGE}/LC_MESSAGES # ${LANGUAGE} is language code such as 'ja'.
    % make update # *.po are updated
    % editor *.po # translate *.po # you can use your favorite editor
    % cd ..
    % make html
    % browser html/index.html # confirm translation
    % git add LC_MESSAGES/*.po
    % git commit
    % git push

    % ./configure --enable-document

The above steps are just needed at the first setup.

If you have troubles on the above steps, you can use source files available on http://packages.groonga.org/source/groonga/ .

## 12.2.2.4. How to update .po files

You can update .po files by running make update on doc/locale/${LANGUAGE}/LC_MESSAGES. (Please substitute ${LANGUAGE} with your language code such as ‘ja’.):

    % cd doc/locale/ja/LC_MESSAGES
    % make update

## 12.2.2.5. How to edit .po

There are some tools to edit .po files. .po files are just text. So you can use your favorite editor. Here is a specialized editor for .po file edit list.
