Add an FAQ and/or high-level overview of how to integrate TUF

We are often asked the same questions regarding delegations, how to organize TUF metadata, key management, etc. There should be an FAQ page for these sorts of questions.

The Survivable Key Compromise paper provides an overview of TUF's design, and the specification and other documents available here capture most of what it contains. However, the integration side of things is not adequately explained outside of the Diplomat and Mercury papers. The PEP 458 document is also a good resource for how to integrate TUF with an existing software updater and community repository.

We should provide a condensed, high-level document that contains the information in the papers and documents that have been written since the Survivable Key Compromise paper.

Survivable Key Compromise、Diplomat、Mercury の論文に加え、PEP 458 のドキュメントと既存の TUF 仕様資料を確認してください。それらの統合に関するガイダンスを、delegations、メタデータの構成、鍵管理を扱う簡潔な FAQ または高レベルの概要に整理してください。統合に関する繰り返し出てくる質問が、1つのアクセスしやすいドキュメントで説明されていれば完了です。
