-
-First, you need to download all records of the current legislative period.
-```r
-fetch_all("../inst/records/") # path to directory where records should be stored
-```
-Second, those `.xml` files, need to be parsed into `R` `tibbles`. This is accomplished by:

-read_all("../inst/records/") %>% repair() -> res
