+
+## Preparation of data
+
+First, you need to download all records of the current legislative period.
+```r
+fetch_all("../records/") # path to directory where records should be stored
+```
+Second, those `.xml` files, need to be parsed into `R` `tibbles`. This is accomplished by:
+```r
+read_all("../records/") %>% repair() -> res
+
+reden <- res$reden
+redner <- res$redner
+talks <- res$talks
+```
+We also used `repair` to fix a bunch of formatting issues in the records and unpacked
+the result into more descriptive variables.
+
+For development purposes, we load the tables from csv files.
+```{r}
+tables <- read_from_csv('../csv/')
+
+comments <- tables$comments
+reden <- tables$reden
+redner <- tables$redner
+talks <- tables$talks
+```
+
+Further, we need to load a list of words that were used by Hitler but not by standard German texts.
+```{r}
+fil <- file('../hitler_texts/hitler_words')
+Worte <- readLines(fil)
+hitlerwords <- tibble(Worte)
+```
+
+## Analysis
+
+Now we extract the words that were used with higher frequency by one party and compare them with `hitlerwords`.
+```{r}
+talks %>% 
+  left_join(redner, by=c(redner='id')) %>% 
+  group_by(fraktion) %>%
+  summarize(full_text=str_c(content, collapse="\n")) -> talks_by_fraktion
+talks_by_fraktion
+```
+For each party, we want to get a tibble of words with frequency.
+```{r}
