+# wkhtmltox
+
+## Running within a container
+
+To use the `wkhtmltopdf` or `wkhtmltoimage` binaries within a container, ensure that the
+environment variable `FONTCONFIG_FILE` is pointed at a `fonts.conf` file that indicates at
+least one fonts directory.
+
+A dummy `fonts.conf` pointing at an empty included `fonts/` directory that can be used to
+avoid the segfault that results from none being available:
+
+    export FONTCONFIG_FILE="`hab pkg path jarvus/wkhtmltox`/fonts.conf"
