+# CC0 1.0 Universal
+
+## Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator and
+subsequent owner(s) (each and all, an “owner”) of an original work of
+authorship and/or a database (each, a “Work”).
+
+Certain owners wish to permanently relinquish those rights to a Work for the
+purpose of contributing to a commons of creative, cultural and scientific works
+(“Commons”) that the public can reliably and without fear of later claims of
+infringement build upon, modify, incorporate in other works, reuse and
+redistribute as freely as possible in any form whatsoever and for any purposes,
+including without limitation commercial purposes. These owners may contribute
+to the Commons to promote the ideal of a free culture and the further
+production of creative, cultural and scientific works, or to gain reputation or
+greater distribution for their Work in part through the use and efforts of
+others.
+
+For these and/or other purposes and motivations, and without any expectation of
+additional consideration or compensation, the person associating CC0 with a
+Work (the “Affirmer”), to the extent that he or she is an owner of Copyright
+and Related Rights in the Work, voluntarily elects to apply CC0 to the Work and
+publicly distribute the Work under its terms, with knowledge of his or her
+Copyright and Related Rights in the Work and the meaning and intended legal
+effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+   protected by copyright and related or neighboring rights (“Copyright and
+   Related Rights”). Copyright and Related Rights include, but are not limited
+   to, the following:
+   1. the right to reproduce, adapt, distribute, perform, display, communicate,
+      and translate a Work;
+   2. moral rights retained by the original author(s) and/or performer(s);
+   3. publicity and privacy rights pertaining to a person’s image or likeness
+      depicted in a Work;
+   4. rights protecting against unfair competition in regards to a Work,
+      subject to the limitations in paragraph 4(i), below;
+   5. rights protecting the extraction, dissemination, use and reuse of data in
+      a Work;
+   6. database rights (such as those arising under Directive 96/9/EC of the
+      European Parliament and of the Council of 11 March 1996 on the legal
+      protection of databases, and under any national implementation thereof,
+      including any amended or successor version of such directive); and
+   7. other similar, equivalent or corresponding rights throughout the world
+      based on applicable law or treaty, and any national implementations
+      thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention of,
+   applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
+   unconditionally waives, abandons, and surrenders all of Affirmer’s Copyright
+   and Related Rights and associated claims and causes of action, whether now
+   known or unknown (including existing as well as future claims and causes of
+   action), in the Work (i) in all territories worldwide, (ii) for the maximum
+   duration provided by applicable law or treaty (including future time
+   extensions), (iii) in any current or future medium and for any number of
+   copies, and (iv) for any purpose whatsoever, including without limitation
+   commercial, advertising or promotional purposes (the “Waiver”). Affirmer
+   makes the Waiver for the benefit of each member of the public at large and
+   to the detriment of Affirmer’s heirs and successors, fully intending that
+   such Waiver shall not be subject to revocation, rescission, cancellation,
+   termination, or any other legal or equitable action to disrupt the quiet
+   enjoyment of the Work by the public as contemplated by Affirmer’s express
+   Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason be
+   judged legally invalid or ineffective under applicable law, then the Waiver
+   shall be preserved to the maximum extent permitted taking into account
+   Affirmer’s express Statement of Purpose. In addition, to the extent the
+   Waiver is so judged Affirmer hereby grants to each affected person a
+   royalty-free, non transferable, non sublicensable, non exclusive,
+   irrevocable and unconditional license to exercise Affirmer’s Copyright and
+   Related Rights in the Work (i) in all territories worldwide, (ii) for the
+   maximum duration provided by applicable law or treaty (including future time
+   extensions), (iii) in any current or future medium and for any number of
+   copies, and (iv) for any purpose whatsoever, including without limitation
+   commercial, advertising or promotional purposes (the “License”). The License
+   shall be deemed effective as of the date CC0 was applied by Affirmer to the
+   Work. Should any part of the License for any reason be judged legally
+   invalid or ineffective under applicable law, such partial invalidity or
+   ineffectiveness shall not invalidate the remainder of the License, and in
+   such case Affirmer hereby affirms that he or she will not (i) exercise any
+   of his or her remaining Copyright and Related Rights in the Work or (ii)
+   assert any associated claims and causes of action with respect to the Work,
+   in either case contrary to Affirmer’s express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+   1. No trademark or patent rights held by Affirmer are waived, abandoned,
+      surrendered, licensed or otherwise affected by this document.
+   2. Affirmer offers the Work as-is and makes no representations or warranties
+      of any kind concerning the Work, express, implied, statutory or
+      otherwise, including without limitation warranties of title,
+      merchantability, fitness for a particular purpose, non infringement, or
+      the absence of latent or other defects, accuracy, or the present or
+      absence of errors, whether or not discoverable, all to the greatest
+      extent permissible under applicable law.
+   3. Affirmer disclaims responsibility for clearing rights of other persons
+      that may apply to the Work or any use thereof, including without
+      limitation any person’s Copyright and Related Rights in the Work.
+      Further, Affirmer disclaims responsibility for obtaining any necessary
+      consents, permissions or other rights required for any use of the Work.
+   4. Affirmer understands and acknowledges that Creative Commons is not a
+      party to this document and has no duty or obligation with respect to this
+      CC0 or use of the Work.

+[<img alt="Discord" src="https://shields.io/badge/Discord-5865F2?logo=discord&logoColor=white">][discord]
+
+[PostCSS Nesting] lets you nest style rules inside each other, following the
+[CSS Nesting] specification. If you want nested rules the same way [Sass] works
+you might want to use [PostCSS Nested] instead.
+
+```pcss
+a, b {
+	color: red;
+
+	/* "&" comes first */
+	& c, & d {
+		color: white;
+	}
+
+	/* "&" comes later, requiring "@nest" */
+	@nest e & {
+		color: yellow;
+	}
+}
+
+/* becomes */
+
+a, b {
+	color: red;
+}
+
+a c, a d, b c, b d {
+	color: white;
+}
+
+e a, e b {
+	color: yellow;
+}
+```
+
+## Usage
+
+Add [PostCSS Nesting] to your project:
+
+```bash
+npm install postcss-nesting --save-dev
+```
+
+Use [PostCSS Nesting] as a [PostCSS] plugin:
+
+```js
+import postcss from 'postcss';
+import postcssNesting from 'postcss-nesting';
+
+postcss([
+  postcssNesting(/* pluginOptions */)
+]).process(YOUR_CSS /*, processOptions */);
+```
+
+[PostCSS Nesting] runs in all Node environments, with special instructions for:
+
+| [Node](INSTALL.md#node) | [Webpack](INSTALL.md#webpack) | [Create React App](INSTALL.md#create-react-app) | [Gulp](INSTALL.md#gulp) | [Grunt](INSTALL.md#grunt) |
+| --- | --- | --- | --- | --- |
+
+### Deno
+
+You can also use [PostCSS Nesting] on [Deno]:
+
+```js
+import postcss from "https://deno.land/x/postcss/mod.js";
+import postcssNesting from "https://cdn.jsdelivr.net/npm/postcss-nesting@10/mod.js";
+
+await postcss([postcssNesting]).process(YOUR_CSS /*, processOptions */);
+```
+
+## Options
+
+### noIsPseudoSelector
+
+#### Specificity
+
+Before :
+
+```css
+#alpha,
+.beta {
+	&:hover {
+		order: 1;
+	}
+}
+```
+
+After **without** the option :
+
+```js
+postcssNesting()
+```
+
+```css
+:is(#alpha,.beta):hover {
+	order: 1;
+}
+```
+
+_`.beta:hover` has specificity as if `.beta` where an id selector, matching the specification._
+
+[specificity: 1, 1, 0](https://polypane.app/css-specificity-calculator/#selector=%3Ais(%23alpha%2C.beta)%3Ahover)
+
+After **with** the option :
+
+```js
+postcssNesting({
+	noIsPseudoSelector: true
+})
+```
+
+```css
+#alpha:hover, .beta:hover {
+	order: 1;
+}
+```
+
+_`.beta:hover` has specificity as if `.beta` where a class selector, conflicting with the specification._
+
+[specificity: 0, 2, 0](https://polypane.app/css-specificity-calculator/#selector=.beta%3Ahover)
+
+
+#### Complex selectors
+
+Before :
+
+```css
+.alpha > .beta {
+	& + & {
+		order: 2;
+	}
+}
+```
+
+After **without** the option :
+
+```js
+postcssNesting()
+```
+
+```css
+:is(.alpha > .beta) + :is(.alpha > .beta) {
+	order: 2;
+}
+```
+
+After **with** the option :
+
+```js
+postcssNesting({
+	noIsPseudoSelector: true
+})
+```
+
+```css
+.alpha > .beta + .alpha > .beta {
+	order: 2;
+}
+```
+
+_this is a different selector than expected as `.beta + .alpha` matches `.beta` followed by `.alpha`._<br>
+_avoid these cases when you disable `:is()`_<br>
+_writing the selector without nesting is advised here_
+
+```css
+/* without nesting */
+.alpha > .beta + .beta {
+	order: 2;
+}
+```
+
+### ⚠️ Spec disclaimer
+
+The [CSS Nesting Module] spec states on nesting that "Declarations occurring after a nested rule are invalid and ignored.".
+While we think it makes sense on browsers, enforcing this at the plugin level introduces several constraints that would
+interfere with PostCSS' plugin nature such as with `@mixin`
