+
+## What is this?
+
+This package provides a (lint) message format.
+
+## When should I use this?
+
+In most cases, you can use `file.message` from `VFile` itself, but in some
+cases you might not have a file, and still want to emit warnings or errors,
+in which case this can be used directly.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 16+), install with [npm][]:
+
+```sh
+npm install vfile-message
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {VFileMessage} from 'https://esm.sh/vfile-message@4'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+<script type="module">
+  import {VFileMessage} from 'https://esm.sh/vfile-message@4?bundle'
+</script>
+```
+
+## Use
+
+```js
+import {VFileMessage} from 'vfile-message'
+
+const message = new VFileMessage(
+  'Unexpected unknown word `braavo`, did you mean `bravo`?',
+  {source: 'spell', ruleId: 'typo', place: {line: 1, column: 8}}
+)
+
+console.log(message)
+```
+
+Yields:
+
+```txt
+[1:8: Unexpected unknown word `braavo`, did you mean `bravo`?] {
+  reason: 'Unexpected unknown word `braavo`, did you mean `bravo`?',
+  line: 1,
+  column: 8,
+  ancestors: undefined,
+  cause: undefined,
+  fatal: undefined,
+  place: {line: 1, column: 8},
+  ruleId: 'typo',
+  source: 'spell'
+}
+```
+
+## API
+
+This package exports the identifier [`VFileMessage`][api-vfile-message].
+There is no default export.
+
+### `VFileMessage(reason[, options])`
+
+Create a message for `reason`.
+
+> 🪦 **Note**: also has obsolete signatures.
+
+###### Parameters
+
+*   `reason` (`string`)
+    — reason for message (should use markdown)
+*   `options` ([`Options`][api-options], optional)
+    — configuration.
+
+###### Extends
+
+[`Error`][mdn-error].
+
+###### Returns
+
+Instance of `VFileMessage`.
+
+###### Fields
+
+*   `ancestors` ([`Array<Node>`][unist-node] or `undefined`)
+    — stack of (inclusive) ancestor nodes surrounding the message
+*   `cause` ([`Error`][mdn-error] or `undefined`)
+    — original error cause of the message
+*   `column` (`number` or `undefined`)
+    — starting column of message
+*   `fatal` (`boolean` or `undefined`)
+    — state of problem; `true`: error, file not usable; `false`: warning,
+    change may be needed; `undefined`: info, change likely not needed
+*   `line` (`number` or `undefined`)
+    — starting line of message
+*   `place` ([`Point`][unist-point], [`Position`][unist-position] or `undefined`)
+    — place of message
+*   `reason` (`string`)
+    — reason for message (should use markdown)
+*   `ruleId` (`string` or `undefined`, example: `'my-rule'`)
+    — category of message
+*   `source` (`string` or `undefined`, example: `'my-package'`)
+    — namespace of message
+
+### `Options`
+
+Configuration (TypeScript type).
+
+###### Fields

+
+### Well-known
+
+It’s OK to store custom data directly on the `VFileMessage`, some of those are
+handled by [utilities][util].
+The following fields are documented and typed here.
+
+###### Fields
+
+*   `actual` (`string`, optional)
+    — specify the source value that’s being reported, which is deemed incorrect
+*   `expected` (`Array<string>`, optional)
+    — suggest acceptable values that can be used instead of `actual`
+*   `url` (`string`, optional)
+    — link to docs for the message (this must be an absolute URL that can be
+    passed as `x` to `new URL(x)`)
+*   `note` (`string`, optional)
+    — long form description of the message (you should use markdown)
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports the additional type [`Options`][api-options].
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with maintained
+versions of Node.js.
+
+When we cut a new major release, we drop support for unmaintained versions of
+Node.
+This means we try to keep the current release line, `vfile-message@^4`,
+compatible with Node.js 16.
