 Note: package-lock.json file was generated by Node version 18 and npm version 9. The app supports Node 18 as well as multiple versions of npm, but we should always use those versions when updating package-lock.json, unless it is decided to upgrade those, and in this case the readme should be updated as well. If using a different version for node OR npm, please delete the package-lock.json file prior to installing node packages and also prior to pushing to github.
 
-If updating or adding a dependency, please double check that you are working on Node version 9 and npm version 9 and run ```npm update <package_name>```  or ```npm install <package_name>``` (avoid running npm install for updating a package). After updating the package, please make sure that the changes in the package-lock.json reflect only the updated/new package prior to pushing the changes to github.
