 The third major subsystem in Vespa is responsible for managing configuration, clusters, application deployment and similar.
 It is implemented in Java.
 
+- [configserver](https://github.com/vespa-engine/vespa/tree/master/configserver) - the server to which applications are deployed, and nodes send requests for the configuration derived from these deployments.
+- [config-model](https://github.com/vespa-engine/vespa/tree/master/config-model) - a model of the running system specified by a deployed application, which returns config instances on request given a config type name and config id (associated with a role).
+- [config](https://github.com/vespa-engine/vespa/tree/master/config) - client-side library on both Java and C++ for subscribing to configs (by type name and id) and reading config payloads.
+- [configgen](https://github.com/vespa-engine/vespa/tree/master/configgen) - generation of config classes in C++ and Java for reading (and building) a config given its type.
+- [config-proxy](https://github.com/vespa-engine/vespa/tree/master/config-proxy) - client node-side proxy between config subscriptions (issued by config) and the config server.
+- [configdefinitions](https://github.com/vespa-engine/vespa/tree/master/configdefinitions) - config type definitions which are referenced by multiple modules.
