There's no mining software. Waves has LPoS. There are two ways to become a miner in Waves Platform:
1. You can run your own fullnode. You can find all important information related to the process of setting up a node by reading the following docs:
https://docs.wavesplatform.com/waves-full-node/how-to-install-a-node/how-to-install-a-node.html
https://docs.wavesplatform.com/waves-full-node/how-to-configure-a-node.html
Also in case if you have any certain questions about nodes - then feel free to join our Discord server: https://discord.gg/cnFmDyA channel #fullnode and the same thread on our official forum: https://forum.wavesplatform.com/c/full-node
2. You can lease your WAVES. Here's a guide about how to get started with it: https://docs.wavesplatform.com/en/waves-client/account-management/waves-leasing.html
