 ## Dependencies
 
 To build the R package, you first need to install the dependencies:
 
-```r
+``` r
 # install.packages("pak", repos = sprintf("https://r-lib.github.io/p/pak/stable/%s/%s/%s", .Platform$pkgType, R.Version()$os, R.Version()$arch))
 pak::pak()
 ```
 
 ### Developing with Extensions
-If you wish to build or add extensions to the R package you first need to build duckdb with the 
-`extension_static_build` flag. The following commands allow you to add the httpfs extension to 
-a duckdb R build. See the [extension ReadMe](https://github.com/duckdb/duckdb/tree/master/extension#readme) for more 
-information about extensions

 Then in R
-```r
+
+``` r
 library(duckdb)
 con <- DBI::dbConnect(duckdb(config=list('allow_unsigned_extensions'='true')))
 dbExecute(con, "LOAD '{{path_to_duckdb}}/build/release/extension/httpfs/httpfs.duckdb_extension'")
 ```
