This will require re-indexing the site
Also, the content will require another revision as there have been updates (such as refactors) to some of the mentioned portions

EVM Equivalence section:

• Let's change this – make it more about how Omni validators are running exactly the same EVM code as L1 validators. So developers need to make zero changes to their smart contracts or worry about opcode compatibility issues. All developer tooling that works on L1 works with the Omni EVM. Often, EVM chains will be "EVM compatible" but they will have small differences in how the EVM works that developers need to be aware of, they won't support all opcodes, and/or won't include the latest EVM upgrades. Since omni validators run an unmodified EVM client, developers don't need to think about any of these problems on the Omni evm.
