## What it is
The former home of the import maps proposal, which allowed controlling how browsers resolve JavaScript ES module specifiers via a JSON map in HTML. The feature has been merged into the WHATWG HTML Standard, and this repository now only points to the spec, MDN docs, and archived historical versions of the explainer and reference implementation.

## Use cases
- remap bare module specifiers like 'lodash' to CDN URLs in the browser
- use ES modules without a bundler or build step
- understand how import maps work in HTML
- find the current specification for import maps
- learn about import map integrity metadata and multiple import maps
- resolve module names to different versions per page

## When to choose
- you want to read the archived explainer or history of the import maps proposal
- you need links to the official HTML Standard and MDN documentation for import maps

## When to avoid
- you need an up-to-date reference implementation or explainer - use the HTML Standard and MDN instead
- you want to file issues about import maps behavior - they belong with WHATWG now
- you need a tool or library - this is a specification document repository
