# Wiki Links Wiki links are the internal links that connect the files in your knowledge base. To create a wiki link use `[[` and type the name of another file in your repo, for example [[graph-visualization]] You can also create a [[placeholder]]. A placeholder is a wiki link that doesn't have a target file. They can still be helpful to highlight connections. Open the graph with `Foam: Show Graph` command, and look at the placeholder node.
