 Today, we are announcing the open and public availability of "Data Literacy with Data Commons" which comprises curriculum/course materials for instructors, students and other practitioners working on or helping others become _data literate_. This includes detailed modules with pedagogical narratives, explanations of key concepts, examples, and suggestions for exercises/projects focused on advancing the _consumption_, _understanding_ and _interpretation_ of data in the contemporary world. In our quest to expand the reach and utility of this material, we assume no background in computer science or programming, thereby removing a key obstacle to many such endeavors.
 
-This material can be accessed on our [courseware page](/courseware/data_literacy/course_materials.html) and it is open for anyone to take advantage of. If you use any of this material, we would love to hear from you!

 ### What is it?
 
-A set of [modules](/courseware/data_literacy/course_materials.html#modules) focusing on several [key concepts](/courseware/data_literacy/topics.html#key-themes) focusing on data modeling, analysis, visualization and the (ab)use of data to tell (false) narratives. Each module lists its objectives and builds on a pedagogical narrative around the explanation of key concepts, e.g. the differences between correlations and causation. We extensively use the Data Commons platform to point to _real world_ examples without needing to write a single line of code!

 ### Who is this for?
 
-Anyone and everyone. Instructors, students, aspiring data scientists and anyone interested in advancing their data comprehension and analysis skills without needing to code. For instructors, the [curriculum page](/courseware/data_literacy/course_materials.html) details the curriculum organization and how to find key concepts/ideas to use.
