 ### Config.
@@ -157,13 +124,15 @@ The script sets the following keys in Redis:
 * `bitcoin-to-neo4j` - This stores the number of the current blk.dat file, and it's position in that file.
 * `bitcoin-to-neo4j:orphans` - This stores the blockhashes of orphan blocks. You see, the blocks in the blk.dat files are not stored in order (based on their height), so by saving blocks that we cannot calculate a height for yet (because we haven't encountered the block it builds upon), we are able set the height later on.
 * `bitcoin-to-neo4j:tip` - This is the height of the current longest chain we have got in Neo4j. It's not needed for the script to work, but it's useful for seeing the progress of the script.
+* `bitcoin-to-neo4j:log` - Logs showing the amount of time that the blkXXXXX.dat files took to be imported.
 
 When Redis is installed, you can look at each of these with:
 
 ```bash
 redis-cli hgetall bitcoin-to-neo4j
 redis-cli hgetall bitcoin-to-neo4j:orphans
 redis-cli hgetall bitcoin-to-neo4j:tip
+redis-cli hgetall bitcoin-to-neo4j:log
