+# 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)
+
+Extracts and remove (if removeRules is equal true) from PostCSS tree `:import` and `: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'
+    }
+  }
+*/
+```
+
+## createICSSRules(icssImports, icssExports)
+
+Converts icss imports and exports definitions to postcss ast
+
+```js
+createICSSRules({
+  colors: {
+    a: 'b'
+  }
+}, {
+  c: 'd'
+})
+```
