+# Diplodoc utils
+
+[![NPM version](https://img.shields.io/npm/v/@diplodoc/utils.svg?style=flat)](https://www.npmjs.org/package/@diplodoc/utils)
+
+Diplodoc cross-packages utils.
+
+## Motivation 
+
+The Diplodoc ecosystem consists of many packages that have similar problems and needs. This package will contain all the general logic that is duplicated in our code base.
+
+## Table of contents
+
+### AttrsParser 
+
+### Purpose
+
+Support [markdown-it-attrs](https://github.com/arve0/markdown-it-attrs)-like attributes parser. Used in custom Diplodoc MarkdownIt plugins to add classes and anchors, enabling subsequent customization through CSS.
+
+### Interface 
+
+```typescript
+    /* 
+        optional first query
+        if provided parser will parse it imminently
+        each 'parse' call is pure
+    */
+    const attrs = new AttrsParser('{.class #id data-name=diplodoc}');
+
+    attrs.state /* { class: ['class'], id: ['id'], 'data-name': ['diplodoc'] } */
+
+    const other = attrs.parse('{data-wide title="Support quotes too"}')
+
+    other /* { attr: ['data-wide'], title: ['Support quotes too'] }
+```
