+  - Why v12.0.0? Because this is the first LTS release of Node.js v12 and is the earliest version Ganache supports.
   - recommendation: use [nvm](https://github.com/nvm-sh/nvm) on Linux and macOS, and [nvm-windows](https://github.com/coreybutler/nvm-windows) on
     Windows, to configure your node version.

 These are guidelines, not rules. :-)
 
-- Use Node.js v10.13.0 for most local development.
+- Use Node.js v12.0.0 for most local development.
 - Use `bigint` literals, e.g., `123n`; if the number is externally configurable and/or could exceed
   `Number.MAX_SAFE_INTEGER`.
 - Write tests.
