=== Installing Distribution Files The Keycloak Server has two downloadable distributions: * 'keycloak-{project_version}.[zip|tar.gz]' * 'keycloak-overlay-{project_version}.[zip|tar.gz]' The 'keycloak-{project_version}.[zip|tar.gz]' file is the server only distribution. It contains nothing other than the scripts and binaries to run the Keycloak Server. To unpack this file just run your operating system's `unzip` or `gunzip` and `tar` utilities. The 'keycloak-overlay-{project_version}.[zip|tar.gz]' file is a WildFly add-on that allows you to install Keycloak Server on top of an existing WildFly distribution. We do not support users that want to run their applications and Keycloak on the same server instance. To install the Keycloak Service Pack, just unzip it in the root directory of your WildFly distribution, open the bin directory in a shell and run `./jboss-cli.[sh|bat] --file=keycloak-install.cli`. To unpack of these files run the `unzip` or `gunzip` and `tar` utilities.
