+# ICSS — Replace Symbols
+
+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 Constants](https://github.com/css-modules/postcss-modules-constants))
+
+## API
+
+```js
+import replaceSymbols from "icss-replace-symbols"
+replaceSymbols(css, translations)
+```
+
+Where:
+
+- `css` is the PostCSS tree you're working with
+- `translations` is an JS object of `symbol: "replacement"` pairs, where all occurrences of `symbol` are replaced with `replacement`.
+
+## Behaviour
+
+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 {}`
