 /**
- * Step 1: Update URLs in chain.json and assetlist.json files
- * Example:
- * "https://raw.githubusercontent.com/initia-labs/initia-registry/main/initia/images/INIT.png"
- * will be replaced with
- * "https://registry.initia.xyz/initia/images/INIT.png"
+ * Main script for processing network registry files.
+ * 
+ * The process consists of three steps:
+ * 1. Updating URLs in chain.json and assetlist.json files.
+ *    Example transformation:
+ *    - From: https://raw.githubusercontent.com/initia-labs/initia-registry/main/initia/images/INIT.png
+ *    - To: https://registry.initia.xyz/initia/images/INIT.png
  *
- * Step 2: Aggregate all chains into a single chains.json file
- * Only specific properties are included in the aggregation.
+ * 2. Aggregating all chain.json files into a single chains.json file.
+ *    Only specific properties from each chain are included.
  *
- * Step 3: Optimize images in the directory
+ * 3. Optimizing images in the directory.
