-> Note: if you do not wish to run the `install.sh` wizard but want to use Docker commands directly, follow the [manual setup guide](advanced/manual-setup.md). We do however encourage the use of `install.sh` as it will guide you through all configuration steps and allow for easy updating your AliasVault instance later.
