+The `install-arrow.R` file also includes the `download_optional_dependencies()`
+function. Normally, when installing on a computer with internet access, the
+build process will download third-party dependencies as needed. This function
+provides a way to download them in advance. Relevant environment variables are
+`ARROW_THIRDPARTY_DEPENDENCY_DIR` for the directory of downloaded dependencies
+and `TEST_OFFLINE_BUILD` to force the build process not to download.
Review comment:
Should I also remove it from the summary at the end of this vignette? It
seems helpful to mention it somewhere, but I could also move the comment to the
Developing vignette.
