 # Fast, accurate and scalable probabilistic data linkage
 
@@ -15,11 +16,11 @@ Splink is a Python package for probabilistic record linkage (entity resolution)
 
 ## Key Features
 
-⚡ **Speed:** Capable of linking a million records on a laptop in around a minute.  
-🎯 **Accuracy:** Support for term frequency adjustments and user-defined fuzzy matching logic.  
-🌐 **Scalability:** Execute linkage in Python (using DuckDB) or big-data backends like AWS Athena or Spark for 100+ million records.  
-🎓 **Unsupervised Learning:** No training data is required for model training.  
-📊 **Interactive Outputs:** A suite of interactive visualisations help users understand their model and diagnose problems.
