+
+## API-first. Fast. Easy.
+
+Our HTTP API gives you control over your content stored in the Google Drive folder. Create files, work with Documents and Spreadsheets to deliver content with our Edge network.
+
+The published content is headless which allows different architecture parts to be composed with doc2.site to build a custom and unique solution to fit your requirements.
+
+### Unstructured and structured content
+
+Unstructured content stored in Google Docs is transformed into Structured Content powered by the open-source Unified ecosystem.
+
+First, any representation data in the content is stripped off then the content is structured into smaller reasonable pieces. Delivered is hast for consumption by developers ranging from beginners to experts for any type of application. References can be linked together to build reusable content following the write once, use everywhere mantra.  
+
+Structured content in Google Sheets is parsed and represented as data models delivered in JSON format. Authors can link Spreadsheets in Documents to express relations of unstructured content with structured content and vice versa. For example, in the context of a restaurant, an author can store the menu with price, description etc. in a Spreadsheet and link it to a Menu Document.
+
+Filter and query content by leveraging the powerful JSON query language JMESPath via our API on any published JSON content. For documents, use the more natural DOM query selector to retrieve fragments of content.
