# Install Regen
The following instructions are for building the regen
binary from source, also available at Install Regen alongside general information about the regen
binary.
A significant difference here is that the genesis binary is used for each chain because a validator node needs to start from genesis (unless Using State Sync).
The following instructions also assume that you have already completed Initial Setup.
