 ## Features
 
-- Simplicity: Dust is designed to be easy to learn and powerful to use, without compromising either.
+- Simplicity: Dust is designed to be easy to learn.
 - Speed: Dust is built on [Tree Sitter] and [Rust] to prioritize performance and correctness.
-- Data format: Dust is data-oriented, so first and foremost it makes a great language for defining data.
+- Data format: Dust is data-oriented, making it a great language for defining data.
-- Pipelines: Like a pipe in bash, dust features the yield `->` operator.
 - Format conversion: Effortlessly convert between dust and formats like JSON, CSV and TOML.
 - Structured data: Dust can represent data with more than just strings. Lists, maps and tables are easy to make and manage.

 ### Lists
 
-Lists are sequential collections. They can be built by grouping values with square brackets. Commas are optional. Values can be indexed by their position to access their contents. Their contents can be indexed using dot notation with an integer. Dust lists are zero-indexed.
