Once the [installation](A1_installation.html) is completed the (shiny) app can be started locally which is described below.

## Case 1) First app launch or force data update

If you start the app for the first time you need to set the parameter "use_live_data = TRUE", so that the:


1. Latest operational data is downloaded from the mySQL Database and


2. Analytics data is imported from the file 'analytics.xlsx' (see [Installation, Step 4.2](A1_installation.html#analytics-spreadsheet-file-analytics-xlsx))


```r
aquanes.report::run_app(use_live_data = TRUE)
```


***This step also always needs to be performed in case you want to import the latest operational and analytical data!***



## Case 2) Subsequent app launch (without data update)

If you start the app for at least a second time (i.e. after having at least
once performed step 5.1) and do not need up-to-date operational and analytical
data, it is sufficient to run the following code (i.e. with "use_live_data = FALSE"):

```r
aquanes.report::run_app()
```
