+### Using goma (Googlers only)
+
+If you would like to build using goma, pass `use_goma=1` to `gyp_pdfium`. If
+you installed goma in a non-standard location, you will also need to set
+`gomadir`. e.g.
+
+```
+build/gyp_pdfium -D use_goma=1 -D gomadir=path/to/goma
+```

 ## Building the code
 
 If you used Ninja, you can build the sample program by: `ninja -C out/Debug
