## What Is It?

A standard process for finding and reading existing documents in the system. Ensures team members can quickly locate the right document by number, type, or topic.

---

## Steps

1. **By number** — if you know the ACID number, read it directly:
   ```bash
   af read COR-1001    # read a specific document by PREFIX-ACID
   af read ALF-2100
   ```

2. **By type** — list all documents and filter visually or by type:
   ```bash
   af list             # shows all documents across all layers with type codes
   ```

3. **By keyword** — list and scan titles, or read relevant documents:
   ```bash
   af list             # scan titles for relevant documents
   ```

4. **By prefix** — list shows prefix and layer for each document:
   ```bash
   af list             # PKG layer shows COR docs; PRJ/USR show project-specific docs
   ```

## Document Structure

Every document starts with a header block:

```
# SOP-ACID: Title
Applies to: ...
Last updated: YYYY-MM-DD
```

Read the **What Is It?** section first for a quick summary, then drill into specific sections as needed.
