 ### Troubleshooting
 
 The above commands may fail with various errors, depending on your operating system and dependency versions. Some troubleshooting steps to follow:
 
 - Uninstall global versions of the Ignite CLI via `npm uninstall -g ignite-cli` and use the CLI via `npx ignite-cli`
-- Make sure you are using a reasonably recent version of Node. This can be checked via the `node --version` command. If you require multiple Node versions on your system, install `nvm`, and then run `nvm install --lts`. At the time of writing, Node LTS is v16.x.x.
+- Make sure you are using a reasonably recent version of Node. This can be checked via the `node --version` command. If you require multiple Node versions on your system, install `nvm`, and then run `nvm install --lts`. At the time of writing, Node LTS is v20.x.x.
 - If the installation fails because of an Xcode error (missing Xcode command line tools), the easiest way to install them is to run `sudo xcode-select --install` in your terminal.
 - If Xcode and command line tools are already installed, but the installation complains about missing patch dependencies, you may need to switch the Xcode location to something else: `sudo xcode-select -s /Applications/Xcode.app/Contents/Developer`
 - Opening the project in Xcode can give you other insights into what's happening: `open ./ios/<yourapp>.xcworkspace`
 - Add the `--debug` switch to the Ignite CLI new command to provide additional output during project initialization
 
-Note:
-
-- Navigation persistence is OFF by default in production.
-- Error boundary is set to 'always' display by default.
