+Building systems with SERV
+**************************
+
+A CPU is only as good as its eosystem. In order to make use of SERV, it needs to be combined with other components such as memories, accelerators and peripheral controllers.
+
+Welcome to the reservoir, a pool of ready-made designs and subsystems for different purpsoses that you can use to quickly get started with SERV or integrate it into larger designs.
