+This page provides pointers to high-level information for WRENCH users who
+want to build simulators. The examples provided  in the  ```example/```
+directory are a great first start. This page goes further by detailing what
+possibilities are available to users beyond what  is shown in the examples.
 
-WRENCH currently provide the following (simulated) CyberInfrastructure Service implementations:

+
+## Simulated Platform Hardware Configurations
+
+A WRENCH simulator must specify the hardware configuration of the platform
+to be simulator (i.e., compute resources, storage resources, network
+resources). WRENCH does not do anything specific and accepts any valid
+[SimGrid platform description in
+XML](https://simgrid.org/doc/latest/platform.html).  The documentation is
+extensive, as many options are possible. We strongly suggest users to
+inspect the platform  files provided  with the  WRENCH examples (in
+directory ```examples/simple-example/platform_files/```). These  files are
+simply passed to the ```wrench::Simulation::instantiatePlatform()```
+method.

+## Simulated CyberInfrastructure Services
+
+A WRENCH simulation consists in a WMS  (Workflow Management System) that interacts with CyberInfrastructure Service. Several such (simulated) services are implemented in WRENCH and can thus be instantiated on the simulation platform out-of-the-box.  The examples in the ```examples``` directory showcase the use of some of these services, but there are others! WRENCH currently provide the following CyberInfrastructure services:

+## Simulation Output
+
+The goal of any simulator is to generate output that describes a simulated
+execution, the outcomes of which can be analyzed for whatever purposes. The
+class ```wrench::SimulationOutput``` contains all relevant information
+(once the simulation has completed). This information can be accessed via
+this class' API (see the relevant documentation in the API Reference
+section). Note that there are also  methods to configure the type  and amount of
+output generated (see the
+```wrench::SimulationOutput::enable*Timestamps()``` methods).
+
+The simulation output can be exported to a JSON file,  using one of the
+```wrench::SimulationOutput::dump*JSON()``` methods. See the documentation of each method to see the structure of the JSON output, in case  you want to parse/process the JSON yourself. Alternately, you  can use the 
+**WRENCH dashboard** to open the JSON and gain access to interactive  visualization/inspection tools. To do so simple  run ```tools/wrench/wrench-dashboard```.
