 ### Dive Deeper into the Architecture
 
 For those interested in gaining a deeper understanding of Erigon's underlying architecture, visit the following resources:
+
 - **[DB Walk-through](https://github.com/erigontech/erigon/blob/release/2.60/docs/programmers_guide/db_walkthrough.MD)**: This document provides a detailed walk-through of Erigon's database structure. It explains how Erigon organizes persistent data into tables like PlainState for accounts and storage, History Of Accounts for tracking account changes, and Change Sets for optimized binary searches on changes. It contrasts Erigon's approach with go-ethereum's use of the Merkle Patricia Trie.
 - **[Database FAQ](https://github.com/erigontech/erigon/blob/release/2.60/docs/programmers_guide/db_faq.md)**: The Database FAQ addresses common questions and concerns related to Erigon's database design. It covers how to directly read the database via gRPC or while Erigon is running, details on the MDBX storage engine and RAM usage model, and points to further resources on the database interface rationale and architecture.

 ### Feature Exploration
+
 Erigon introduces several innovative features that contributors may find interesting to explore and contribute to:
+
 - **[DupSort Feature Explanation](https://github.com/erigontech/erigon/blob/release/2.60/docs/programmers_guide/dupsort.md)**: Erigon's DupSort feature optimizes storage and retrieval of duplicate data by utilizing prefixes for keys in databases without the concept of "Buckets/Tables/Collections" or by creating tables for efficient storage with named "Buckets/Tables/Collections."
 - **[EVM without Opcodes](https://github.com/erigontech/erigon/blob/release/2.60/docs/evm_semantics.md)** (Ether Transfers Only): Erigon explores a simplified version of the Ethereum Virtual Machine (EVM) focusing solely on ether transfers, offering an efficient execution environment for specific use cases.
