+
+### Configuration
+
+The configuration controls all aspects of EOS: optimization, prediction, measurement, and energy management.
+
+### Energy Management
+
+Energy management is the overall process to provide planning data for scheduling the different devices in your system in an optimal way. Energy management cares for the update of predictions and the optimization of the planning based on the simulated behavior of the devices. The planning is on the hour. Sub-hour energy management is left
+
+### Optimization
+
+### Device Simulations
+
+Device simulations simulate devices' behavior based on internal logic and predicted data. They provide the data needed for optimization.
+
+### Predictions
+
+Predictions provide predicted future data to be used by the optimization.
+
+### Measurements
+
+Measurements are utilized to refine predictions using real data from your system, thereby enhancing accuracy.
+
+### EOS Server
+
+EOS operates as a [REST](https://en.wikipedia.org/wiki/REST) [API](https://restfulapi.net/) server.
+
+### EOSdash
+
+`EOSdash` is a lightweight support dashboard for EOS. It is pre-integrated with EOS. When enabled,
+it can be accessed by navigating to [http://localhost:8503](http://localhost:8503) in your browser.
