+# ICSS Utils
+
+## replaceSymbols
+
+Governs the way tokens are searched & replaced during the linking stage of ICSS loading.
+
+This is broken into its own module in case the behaviour needs to be replicated in other PostCSS plugins
+(i.e. [CSS Modules Values](https://github.com/css-modules/postcss-modules-values))
+
+```js
+import { replaceSymbols, replaceValueSymbols } from "icss-utils";
+
+replaceSymbols(css, replacements);
+replaceValueSymbols(string, replacements);
+```
+
+Where:
+
+- `css` is the PostCSS tree you're working with
+- `replacements` is an JS object of `symbol: "replacement"` pairs, where all occurrences of `symbol` are replaced with `replacement`.
+
+A symbol is a string of alphanumeric, `-` or `_` characters. A replacement can be any string. They are replaced in the following places:
+
+- In the value of a declaration, i.e. `color: my_symbol;` or `box-shadow: 0 0 blur spread shadow-color`
+- In a media expression i.e. `@media small {}` or `@media screen and not-large {}`
+
+## extractICSS(css, removeRules = true, mode = 'auto')
+
+Extracts and remove (if removeRules is equal true) from PostCSS tree `:import`, `@icss-import`, `:export` and `@icss-export` statements.
+
+```js
+import postcss from "postcss";
+import { extractICSS } from "icss-utils";
+
+const css = postcss.parse(`
+  :import(colors) {
+    a: b;
+  }
+  :export {
+    c: d;
+  }
+`);
+
+extractICSS(css);
+/*
+  {
+    icssImports: {
+      colors: {
+        a: 'b'
+      }
+    },
+    icssExports: {
+      c: 'd'
+    }
+  }
+*/
+```
+
+By default both the pseudo and at-rule form of the import and export statements
+will be removed. Pass the `mode` option to limit to only one type.
+
+## createICSSRules(icssImports, icssExports, mode = 'rule')
+
+Converts icss imports and exports definitions to postcss ast
+
+```js
+createICSSRules(
+  {
+    colors: {
+      a: "b",
+    },
+  },
+  {
+    c: "d",
+  },
+  // Need pass `rule` and `decl` from postcss
+  // Please look at `Step 4` https://evilmartians.com/chronicles/postcss-8-plugin-migration
+  postcss
+);
+```
+
+By default it will create pseudo selector rules (`:import` and `:export`). Pass
+`at-rule` for `mode` to instead generate `@icss-import` and `@icss-export`, which
+may be more resilient to post processing by other tools.
