-[Usage examples](../examples)
+SPARQL Blockly is a library for visualising and building SPARQL.
+
+## Usage
+- **[Try it online](https://langsamu.github.io/sparql-blockly/)**
+- See the [examples](../examples)
+
+## Features
+
+SPARQL Blockly implements the [SPARQL](https://www.w3.org/TR/sparql11-query/) grammar in [Blockly](https://developers.google.com/blockly).
+
+It supports SPARQL 1.1 Query, Update and SPARQL*.
+
+![screenshot](../screenshot.png)
+
+It enables several ways of visual interaction with SPARQL:
+- Dragging blocks from a toolbox unto a canvas to assemble valid queries.
+- Adding clauses and patterns to query blocks using a context menu.
+- Parsing SPARQL query text into blocks.
+- Collapsing/expanding parts of a query assemblage.
+- Sharing URLs of visual representations.
+
+SPARQL is parsed using [SPARQL.js](https://github.com/RubenVerborgh/SPARQL.js/).
