+## Extracting binaries
+
+Hints for extracting binaries from https://wkhtmltopdf.org/downloads.html (dpkg and rpm2cpio is available on Homebrew).
+
+Debian/Ubuntu
+
+    dpkg -x wkhtmltox_0.12.5-1.trusty_amd64.deb .
+
+CentOS
+
+    rpm2cpio wkhtmltox-0.12.5-1.centos7.x86_64.rpm | cpio -idmv
+
+macOS
+
+    xar -xf wkhtmltox-0.12.5-1.macos-cocoa.pkg
+    cat Payload | gunzip -dc | cpio -i
+
+## Compression
+
+Binaries should be compressed with `gzip --best` after extracting. The matching binary will be extracted on first
+execution of `bin/wkhtmltopdf`.
+
+## Testing with Docker
+
+Make sure you have Docker and Docker Compose installed (see https://docs.docker.com/compose/install/ for more
+information).
+
+There are Dockerfiles for the supported Linux based distributions under `.docker`. You can build them all with
+`docker-compose build` and run each individually with e.g. `docker-compose run ubuntu_18.04`.
+
+There also is a rudimentary minitest test that simply invokes `docker-compose run` for each distribution and
+expects to see the output of `wkhtmltopdf --version`. Just run `rake` to run it. 
+
+You can clean up after testing with `docker-compose down --rmi all`.
