Add Capital One as a Known Instance for the InnerSource Ambassador

pattern: InnerSource Ambassadors

@spier This does a great job at capturing all of the elements for IS ambassadors.

To answer your questions, yes it's a good description of what we are doing. Some additions I would suggest are:
a) where you say "are enthusiastic about IS", I would add "and ideally have experience using open source practices".
b) add info on 'what's in it for the ambassadors'. For example, it provides opportunity and topic for ambassadors to reach out and engage beyond their immediate teams. it provides opportunity for learning, enhancing influence, problem-solving, and communication skills, opportunity to share their expertise and passion in a structured way, and to network with like-minded enthusiasts.

re: whether Capital One is an org that has implemented the pattern:
I would not list Capital One yet. What is described in the pattern is our intent, but we are not yet an example of one that has fully implemented the pattern.

The InnerSource Flywheel

從 issue 中連結的 InnerSource Ambassadors 模式開始，並查看所引用的 InnerSource Flywheel 演講以了解背景。釐清是否應該列出 Capital One，因為討論明確表示目前不應將其視為已實作的範例；done 應是一項明確的決定，以及在獲得核准的情況下對相應模式的更新。
