+# Seeds
 
 Utility to generate the seeds.txt list that is compiled into the client
 (see [src/chainparamsseeds.h](/src/chainparamsseeds.h) and other utilities in [contrib/seeds](/contrib/seeds)).
 
+Be sure to update `PATTERN_AGENT` in `makeseeds.py` to include the current version,
+and remove old versions as necessary.
+
 The seeds compiled into the release are created from sipa's DNS seed data, like this:
 
     curl -s http://bitcoin.sipa.be/seeds.txt > seeds_main.txt
-    python makeseeds.py < seeds_main.txt > nodes_main.txt
-    python generate-seeds.py . > ../../src/chainparamsseeds.h
+    python3 makeseeds.py < seeds_main.txt > nodes_main.txt
+    python3 generate-seeds.py . > ../../src/chainparamsseeds.h
+
+## Dependencies

+Ubuntu:
 
+    sudo apt-get install python3-dnspython
