# Content types

> Decide between knowledge, templates, skills, preferences, and Follow-ups.

Use the kind of content that matches what you want to keep or reuse. A vault
chooses who can access the knowledge; the choices below describe what you store.
For Company, Team, and Personal, see [Core concepts](/getting-started/concepts).

| You have…                                           | Use             | Example                                                  | How it is reused                                                                           |
| --------------------------------------------------- | --------------- | -------------------------------------------------------- | ------------------------------------------------------------------------------------------ |
| A fact, decision, or procedure people should find   | Knowledge page  | An approved client onboarding checklist                  | Read the current page from the app, a replica, or MCP.                                     |
| A starting structure for new vaults                 | Template        | A department wiki layout                                 | Apply once to an empty vault; later template edits do not update the copy.                 |
| Instructions for performing a repeatable agent task | Skill           | Review meeting notes for decisions and missing owners    | Make the instructions available to a compatible tool; the tool performs the work.          |
| Your personal working preferences                   | Personalization | Prefer concise summaries and ask before external sending | Tools can receive authorized profile information through orientation.                      |
| Company-wide writing guidance                       | Company Voice   | Tone, approved terms, prohibited claims, examples        | Configure pointers to ordinary shared knowledge pages.                                     |
| Unfinished work or a review request                 | Follow-up       | Review the draft checklist before Friday                 | Open the referenced page or copy its resume prompt; file durable conclusions in Knowledge. |

## A useful progression

```mermaid theme={null}
flowchart TD
  N[Capture a decision in a page] --> R[Request review with a Follow-up]
  R --> A[Update the approved knowledge]
  A --> S[Write a skill for a repeatable procedure]
  S --> T[Test the skill in your chosen AI tool]
```

A Follow-up is a work item, not an automatic reminder. A skill is reusable
instruction, not a hosted worker. These steps require people or your chosen tool
to carry them out.

## Keep the authoritative copy clear

Knowledge pages are Markdown files. Profiles and Follow-ups are separate product
records and are not part of normal vault sync or ZIP export. A library skill
copied into a vault becomes a separate copy; decide which one you maintain and
redistribute changes deliberately.

**Next:** [Create a reusable skill](/tutorials/reusable-skill) or
[Keep knowledge useful](/knowledge/maintenance).

## Three places a skill can live

| Location                       | Use it for                                                                        | Important boundary                                                                     |
| ------------------------------ | --------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------- |
| **Skills** library             | Authoring, importing, and distributing packages                                   | It is separate from ordinary Knowledge search and vault exports.                       |
| A vault's `skills/` folder     | Markdown instructions available with that vault, including conversion enhancement | Copying creates independent vault files; it does not install a skill in every AI tool. |
| Your AI tool's skill directory | Instructions that the tool can discover and execute                               | Install through the tool's supported mechanism; Northern Logic does not run the skill. |

See [Skills](/library/skills) for copying and distribution, and
[Source conversion](/knowledge/convert) for enhancement requirements.
