This guide assumes you have successfully compiled Accumulate and installed the binary to your path. If the binary is not installed to your path, replace accumulate ... with ./accumulate ..., assuming the binary is in the current directory.
Choose the directory to store configuration and state in, such as .nodes
Choose the base IP address for the first node, such as 127.0.25.1
Choose the number of BVNs to create
Choose the number of validators and followers to create for each subnet
Execute accumulate init devnet [flags]
On macOS, you need to create loopback aliases before you will be able to listen on 127.x.y.z (except 127.0.0.1). To create an alias for 127.0.25.1, execute sudo ifconfig lo0 alias 127.0.25.1.
