+
+a CSS selector parser
+
+## Example
+
+```js
+const CSSwhat = require("css-what")
+CSSwhat.parse("foo[bar]:baz")
+
+~> [
+    [
+        { type: "tag", name: "foo" },
+        {
+            type: "attribute",
+            name: "bar",
+            action: "exists",
+            value: "",
+            ignoreCase: false
+        },
+        { type: "pseudo", name: "baz", data: null }
+    ]
+]
+```
+
+## API
+
+**`CSSwhat.parse(str, options)` - Parses `str`, optionally with the passed `options`.**
+
+The function returns a two-dimensional array. The first array represents selectors separated by commas (eg. `sub1, sub2`), the second contains the relevant tokens for that selector. Possible token types are:
+
+| name             | attributes                              | example       | output                                                                                   |
+| ---------------- | --------------------------------------- | ------------- | ---------------------------------------------------------------------------------------- |
+| `tag`            | `name`                                  | `div`         | `{ type: 'tag', name: 'div' }`                                                           |
+| `universal`      | -                                       | `*`           | `{ type: 'universal' }`                                                                  |
+| `pseudo`         | `name`, `data`                          | `:name(data)` | `{ type: 'pseudo', name: 'name', data: 'data' }`                                         |
+| `pseudo`         | `name`, `data`                          | `:name`       | `{ type: 'pseudo', name: 'name', data: null }`                                           |
+| `pseudo-element` | `name`                                  | `::name`      | `{ type: 'pseudo-element', name: 'name' }`                                               |
+| `attribute`      | `name`, `action`, `value`, `ignoreCase` | `[attr]`      | `{ type: 'attribute', name: 'attr', action: 'exists', value: '', ignoreCase: false }`    |
+| `attribute`      | `name`, `action`, `value`, `ignoreCase` | `[attr=val]`  | `{ type: 'attribute', name: 'attr', action: 'equals', value: 'val', ignoreCase: false }` |
+| `attribute`      | `name`, `action`, `value`, `ignoreCase` | `[attr^=val]` | `{ type: 'attribute', name: 'attr', action: 'start', value: 'val', ignoreCase: false }`  |
+| `attribute`      | `name`, `action`, `value`, `ignoreCase` | `[attr$=val]` | `{ type: 'attribute', name: 'attr', action: 'end', value: 'val', ignoreCase: false }`    |
+| `child`          | -                                       | `>`           | `{ type: 'child' }`                                                                      |
+| `parent`         | -                                       | `<`           | `{ type: 'parent' }`                                                                     |
+| `sibling`        | -                                       | `~`           | `{ type: 'sibling' }`                                                                    |
+| `adjacent`       | -                                       | `+`           | `{ type: 'adjacent' }`                                                                   |
+| `descendant`     | -                                       |               | `{ type: 'descendant' }`                                                                 |
+
+**Options:**
+
+-   `lowerCaseTags`: When false, tag names will not be lowercased. Defaults to `true`.
+-   `lowerCaseAttributeNames`: When false, attribute names will not be lowercased. Defaults to `true`.
+-   `xmlMode`: When `true`, `xmlMode` implies both `lowerCaseTags` and `lowerCaseAttributeNames` are set to `false`.
+
+**`CSSwhat.stringify(selector)` - Turns `selector` back into a string.**
