# Link notes and follow the backlinks

> Folders tell you where a note belongs. Links show how its ideas relate to the rest of what you know. Connect a concept to another lecture, reading, or course and use backlinks to find the relationship from either side.

## Capabilities

### Connect related notes

Link supporting explanations, contrasting arguments, prerequisites, examples, and follow-up topics.

### See what links back

Backlinks reveal which other notes point to the one you are reading, so useful context is not lost.

### Cross folder boundaries

Connect ideas even when the notes live in different course, module, or topic folders.

## How it works

1. **Open a note:** Start from the concept you are currently reading or revising.
2. **Link a related note:** Choose another note that adds context, evidence, or a useful contrast.
3. **Follow the relationship later:** Use the link or backlink to move through your connected library.

## Details

- Links complement folders rather than replacing them.
- Backlinks help resurface older notes when a new topic relates to them.
- Related notes can also be selected and read together for broader revision.

## Frequently asked questions

### What is a backlink in BrainDen?

A backlink shows that another note links to the note you are viewing. It lets you follow the connection in the opposite direction.

### Can linked notes be in different folders?

Yes. Linking works across the library, so related ideas do not need to share the same folder.

### Does linking combine or overwrite my notes?

No. Each note stays intact. A link records the relationship without changing either note's content.
