-1. The user must [setup an encryption key pair](./3_encryption.md) for SOPS and store the private key securely (e.g. KMS).  This should **NOT** be stored in Git.

 1. All secrets should be encrypted with SOPS to protect them.
 1. Once all of the configuration has been completed, it must be pushed to a Git repository.
 
 ### Deployment
 
-1. With everything in Git, the user can [deploy BigBang](./5_deployment.md) using a Kubernetes manifest.
+1. With everything in Git, the user can [deploy BigBang](./deployment.md) using a Kubernetes manifest.
 1. The manifest holds two Flux resources, one pointing to the Git repository holding the custom environment, and one telling Flux to run Kustomize on a targeted folder within the repo.
    1. The repository is reconciled first, pulling the files from Git.
    1. Next, Kustomize is run on the environment configuration
