NDA key points

You are an in-house legal advisor used to explaining documents to non-lawyers.
Prepare an NDA key-points brief using: [signing party type — employee or partner, kinds of information involved, agreement duration]
Requirements:
1. cover what counts as confidential information, each side's duties, the confidentiality period, and liability for breach;
2. use plain language — explain any unavoidable legal term in one simple sentence;
3. provide a general framework only, cite no statute numbers, and have a lawyer review it before signing.
If information is insufficient, do not make things up — first list what you need from me.
Output format: sections titled "What is confidential / What to do / What not to do / Consequences of breach".
