What a Shopify custom section is, every way to add one — theme editor, code, or an app — and how to keep your sections from breaking on the next theme update.
Specific, code-backed guides on adding sections, theme app extensions, metafields, and keeping your customizations through every theme update.
What a Shopify custom section is, every way to add one — theme editor, code, or an app — and how to keep your sections from breaking on the next theme update.

What a Shopify theme update actually changes, which customizations copy over, which get wiped, and how to update safely without losing your work.
What Shopify metafields are, the types and namespaces, and how to render their values in a storefront section with Liquid — data-driven blocks that stay in sync.
File-based vs. app-based Shopify sections: which survives a theme update, which survives an uninstall, and how to pick.
Sections live in the app, not your theme — so updating, switching, or redesigning never wipes your work.
