# Required Software
Prepare to deploy Petro.ai by following the following steps in order:
Install a supported browser (for Petro.ai server and portal)
- If your organization hasn’t installed Spotfire, either install Petro.ai Desktop (from Ruths.ai) or Spotfire Client (v7.10 or later).
Download the MongoDB (for Prod and Test environments)
If you are deploying the database on-prem, navigate to MongoDB’s website and download Community Server (4.0.x or above) on the appropriate machines. These machines are where the replica set will be deployed.
If you are deploying on the cloud, deploy a new cluster and save the connection string.
Install PetroCore (described below)
