Docs for Trusted Committers

There are a couple of things about the way that we maintain this repo that we have not documented yet.
I think that most, if not all of them, are about how we host our patterns in gitbook.

We should document all of them, so that all Trusted Committers (TC) can work independently on this repo.

Things that need further documentation:

• the gitbook setup (incl how to give access to gitbook for further TCs)
• Google Analytics setup (incl how to give access to gitbook for further TCs)
• DNS config for gitbook (dependency to others in the ISC)

ファイルやテストは指定されていません。まず GitBook のセットアップ、Google Analytics へのアクセス、DNS 設定を確認し、ISC 内の他の担当者への依存関係も含めて調査してください。Trusted Committers が文書化された手順を使用して repo を独立して保守できれば完了です。
