-Quartz is a container app template for visualizing corpus data from Sketch Engine servers. It's a portable alternate interface that focuses on graphing quantitative data for linguistic analysis. Set up access to your corpora, make API queries to a Sketch Engine or NoSketch Engine server, and view results with interactive graphs.
+Quartz is a container app template for visualizing corpus data from Sketch Engine servers. It's a portable alternate interface that focuses on graphing quantitative data for linguistic analysis. Set up access to your corpora, make queries via API requests to a Sketch Engine or NoSketch Engine server, and view results with interactive graphs.
 
 Some default graphing features are included, but the repo is designed for adaptation to specific projects. Quartz is made with Python, the Dash framework and Docker. To use it you'll need API access to a Sketch Engine or NoSketch Engine server.

 ### Development
 
-API-based data collection requires understanding the [Sketch Grammar Explorer](https://github.com/engisalor/sketch-grammar-explorer) package (SGEX, a Sketch Engine API wrapper); try it out as a standalone tool if you plan on doing custom data processing. Also see [pages/freqs_viz.py](/pages/freqs_viz.py) for examples of how to make custom visualizations.
