 ### Installing TimescaleDB
 To install TimescaleDB, you need to include it in the server's shared preload libraries. A change to Postgres's `shared_preload_libraries` parameter requires a **server restart** to take effect. You can change parameters using the [Azure portal](howto-configure-server-parameters-using-portal.md) or the [Azure CLI](howto-configure-server-parameters-using-cli.md).
