-# Apache Arrow
+# Apache Arrow 0.14.0
 
-Backported with https://github.com/r-windows/rtools-backports
+Backports for the R legacy toolchain [lib-4.9.3](lib-4.9.3) built with [rtools-backports](https://github.com/r-windows/rtools-backports/blob/master/mingw-w64-arrow/PKGBUILD).
 
-Now fully supports parquet (compile with `-DARROW_R_WITH_PARQUET`).
+Now supports parquet (thrift) and snappy. Example flags to compile and link the R bindings:
+
+```
+PKG_CPPFLAGS = -I$(ARROW_INCLUDE) \
+	-DARROW_R_WITH_ARROW -DARROW_R_WITH_PARQUET \
+	-DARROW_STATIC -DPARQUET_STATIC
+
+CXX_STD = CXX11
+
+PKG_LIBS = \
+	-L$(ARROW_LIBS) \
+	-lparquet -larrow -lthrift \
+	-lboost_system-mt-s -lboost_filesystem-mt-s -lboost_regex-mt-s \
+	-ldouble-conversion -lsnappy -lz -lws2_32
+```
+
+The easiest way to test this is using the R package from the [arrow-r-dev](https://github.com/jeroen/arrow-r-dev) repository:
+
+```r
+remotes::install_github("jeroen/arrow-r-dev")
+```
+
+The upstream R bindings require the libarrow verion from the master branch so it is typically broken.
