 We have been computing these web graphs since 2018, and currently every crawl has
 a web graph covering the previous 3 crawls.

 This repo contains both instructions for using the graphs in neo4j form, and also code to convert from Web Graph
 Framework format to neo4j.

+This project is in beta-testing. Please give it a try with the one Web Graph we've converted: we provide both the domain and host version.
 
-Eventually we will provide all of our web graphs in neo4j format.
+The host Web Graph contains each hostname as a separate node, and links between them as edges.
+The domain Web Graph is built by aggregating the host graph at the pay-level domain (PLD) level based on the public suffix
+list maintained on publicsuffix.org.
+
+> [!TIP]
+> We are collecting feedback on the instructions and the code, and will be making improvements based on your needs and suggestions.
