+## Example application for {shiny.telemetry}
+
+These 2 folders contain an example application that tracks all inputs using `shiny.telemtry` and the accompanying analytics dashboard.
+
+To run the application, install the necessary dependencies:
+
+```R
+install.packages(
+  c(
+    "shiny", "semantic.dashboard", "shiny.semantic", "shiny.telemetry",
+    "dplyr", "config", "shiny.telemtry"
+  ),
+  dependencies = c("Depends", "Imports", "Suggests")
+)
+```
+
+And start the R/Shiny app by: `shiny::runApp("instrumentation")`
+
+Afterwards, the analytics application will have access to the data and can be started by: `shiny::runApp("instrumentation")`
+
+For more information, visit the [documentation](https://appsilon.github.io/shiny.telemetry/) of `shiny.telemetry`
