+## Pruning
+
+As of May 2020, the full Monero blockchain file is about 80 GB. One can store a pruned blockchain, which is about 28 GB.
+A pruned blockchain can only serve part of the historical chain data to other peers, but is otherwise identical in
+functionality to the full blockchain.
+To use a pruned blockchain, it is best to start the initial sync with --prune-blockchain. However, it is also possible
+to prune an existing blockchain using the monero-blockchain-prune tool or using the --prune-blockchain monerod option
+with an existing chain. If an existing chain exists, pruning will temporarily require disk space to store both the full
+and pruned blockchains.

 ## Debugging
 
 This section contains general instructions for debugging failed installs or problems encountered with Monero. First, ensure you are running the latest version built from the Github repo.
