# Overview

`docs/obsidian.md` calls `knowledge_bundle` the **doorway**. It is the link that `ktl-sidecar` creates at the root of the host (the repository or vault the bundle sits in), beside the sidecar's `.lokf/` folder. The link gives the bundle a name a folder picker can see. ktl-docent's `references/obsidian.md` gives the rule for opening it in Obsidian: open the link itself, never the host root. A vault opened at the root lists neither the dot-folder nor the link, which keeps the [workshop](workshop.md) clean.

A host that commits `.lokf/` commits the link too. A host that gitignores `.lokf/` adds the link to the root `.gitignore` instead ([hosts and doorways](../explanation/hosts-and-doorways.md)).
