 # Reaction SMILES Dataset
 
-A curated dataset of 3.4M unique chemical reaction SMILES strings compiled from multiple public sources for use in pre-training and fine-tuning chemical language models.
+A collated dataset of 3.4M unique chemical reaction SMILES strings compiled from multiple public sources for use in pre-training and fine-tuning chemical language models.
 
 Reaction SMILES (Simplified Molecular Input Line Entry System) extend the standard SMILES notation to represent complete chemical reactions. They encode reactants, reagents/catalysts, and products in a single text string using the `>` delimiter:
 
-```
+```text
 reactants>reagents>products
 ```
 
 For example: `CC(=O)O.CCO>[H+]>CC(=O)OCC.O` represents the esterification of acetic acid with ethanol to form ethyl acetate.
