+Optimized for DevOps, architects and engineers to quickly see a cost breakdown and compare different options upfront:
+
+* Mapping of resource usage is done in easy to learn **YAML** usage files
+* Price information is read from a local file
+* Calculation is done via `gcosts` **Linux command line (CLI)** program
+* Calculated costs are saved in **CSV** files
+
 Full control and no disclosure of any information and costs to third parties.
 Everything tested and matched against the actual invoice in large Google Cloud migration projects.
