This configuration is intended mainly for use with versions of the SAPUI5 SDK prior to 1.76.
Simply extract the resource folder to ../ui5/<version>/ (relative to your ui5 project),
change the <strings> accordingly, install NodeJS and execute npm install in this folder.
For details on how to use this repo, see the ui5-tooling documentation.
Starting with SAPUI5 1.76, you might also consume SAPUI5 libraries directly via npm. In this case, the package ui5-middleware-servestatic isn't needed anymore.
