When creating a link from one page to another, its not the exact same as writing standard markdown. Instead, consider the following folder structure:
/my-package/|-- source| |-- index.md| |-- getting-started.md| -- package.json| -- gatsby-config.js
index.md
---title: Intro---Some Content## Some Anchor
If we wanted to create a link getting-started to link to the anchor tag in the index.md file we would do the below.
getting-started.md
---title: Getting Started---If you haven't read the [introduction](/index/#some-anchor) then go back.
You can also hover over the anchored header when its rendered to get the anchor's name.
