+### dnsviz print
+
+`dnsviz print` takes serialized query results in JSON format (i.e., output from
+`dnsviz probe`) as input and assesses specified domain names based on their
+corresponding content in the input.  The output is textual output suitable for
+file or terminal display.
+
+
+#### Examples
+
+Process the query/response output produced by `dnsviz probe`, and output the
+results to the terminal:
+```
+$ dnsviz print < example.com.json
+```
+
+Add DNSSEC trust anchors to the graph:
+```
+$ dig +noall +answer . dnskey | awk '$5 % 2 { print $0 }' > tk.txt
+$ dnsviz print -r example.com.json -t tk.txt
+```
+
+Pipe `dnsviz probe` output directly to `dnsviz print`:
+```
+$ dnsviz probe example.com | \
+      dnsviz print -t tk.txt
+```
+
+Same thing, but save the raw output (for re-use) along the way:
+```
+$ dnsviz probe example.com | tee example.com.json | \
+      dnsviz print -t tk.txt
+```

 ### dnsviz query
 
-`dnsviz query` is a wrapper that couples the functionality of `dnsviz probe` and `dnsviz print` into
-a tool with minimal dig-like usage, used to make analysis queries and return
-the textual output to terminal or file output in one go.
