# Knowledge

> Add contextual documentation to help Addison understand your data and business domain.

<Note>
  This feature is under active development. Details on this page may change.
</Note>

Knowledge documents are contextual documentation attached to [projects](/concepts/projects) that help [Addison](/features/addison) understand your data and business domain. They enrich the [catalog](/features/modeler#catalog) and improve the quality of Addison's results.

## What to include

Good knowledge documents cover things that aren't obvious from the raw data:

* **Metric definitions** — how your organization calculates revenue, churn, LTV, etc.
* **Business glossary** — terms and acronyms specific to your domain
* **Data quirks** — known issues, exclusions, or special cases in your data
* **Domain context** — how your business works, what matters, and why

## Adding knowledge to a project

1. Open a project
2. Go to the Knowledge section
3. Upload or create a document

Knowledge documents are scoped to the project they're attached to. When Addison works in that project, it has access to the knowledge context.

## How it helps

Without knowledge documents, Addison relies on table names, column names, and your catalog to understand your data. Knowledge documents fill in the gaps:

* "Revenue" means net revenue after refunds, not gross
* "Active user" means logged in within the last 30 days
* "Region" column uses internal codes — NA = North America, EMEA = Europe/Middle East/Africa
* Q1 starts in February for this business (non-calendar fiscal year)

The more context you provide, the fewer corrections you'll need to make.
