The placeholder address 0x... in the code example should be replaced with a complete valid Ethereum address format or a more descriptive placeholder like 0x1234...5678 to show the expected format.

[nitpick] The comment mentions 'stable state' but doesn't explain what makes this specific block number stable or how developers should choose their own block number. Consider adding guidance on selecting appropriate fork blocks.
| forkBlockNumber: 18500000, // Use a known good block with stable state | |
| forkBlockNumber: 18500000, // Use a recent, finalized block where the protocol state is stable. | |
| // Choose a block that is not during a major upgrade or reorg, and ideally after all relevant transactions have settled. | |
| // You can find suitable block numbers using a block explorer (e.g., Etherscan) by looking for blocks just before or after important events. |

[nitpick] Using a specific NFT collection (BAYC) in the example may become outdated or unavailable. Consider using a more generic example or explaining how developers should substitute their own collection URLs.

| // Replace <your-nft-collection> with your desired NFT collection slug | |

The comment suggests that using a specific block number reduces memory usage, but this isn't necessarily accurate. Specific block numbers provide reproducibility, while using 'latest' might actually use more memory due to ongoing state changes. The comment should clarify this distinction.
| forkBlockNumber: 18500000, // Specific block reduces memory | |
| forkBlockNumber: 18500000, // Specific block ensures reproducibility and may use less memory than 'latest' |
This PR significantly improves the fork mode documentation to make blockchain forking concepts more accessible to developers. The enhancements focus on clarity, practical examples, and comprehensive troubleshooting support.
What's Changed
Plain-English Explanations
Enhanced Real-World Examples
Comprehensive Troubleshooting
Expanded the troubleshooting section from 6 to 10 common issues:
Improved Navigation
Before/After Comparison
Before: Fork mode documentation was technically accurate but assumed deep blockchain knowledge
After: Documentation now guides developers from basic concepts to advanced troubleshooting with practical examples
The changes maintain all existing functionality while making the toolkit significantly more approachable for developers new to blockchain testing. All code examples are syntactically correct and follow established patterns in the codebase.
