+  def caveats
+    <<~EOS
+      If you intend to run ClickHouse server:
+
+        - Familiarize yourself with the usage recommendations:
+            https://clickhouse.com/docs/en/operations/tips/
+
+        - Increase the maximum number of open files limit in the system:
+            macOS: https://clickhouse.com/docs/en/development/build-osx/#caveats
+            Linux: man limits.conf
+
+        - Set the 'net_admin', 'ipc_lock', and 'sys_nice' capabilities on #{opt_bin}/clickhouse binary. If the capabilities are not set the taskstats accounting will be disabled. You can enable taskstats accounting by setting those capabilities manually later.
+            Linux: sudo setcap 'cap_net_admin,cap_ipc_lock,cap_sys_nice+ep' #{opt_bin}/clickhouse
+
+        - By default, the pre-configured 'default' user has an empty password. Consider setting a real password for it:
+            https://clickhouse.com/docs/en/operations/settings/settings-users/
+
+        - By default, ClickHouse server is configured to listen for local connections only. Adjust 'listen_host' configuration parameter to allow wider range of addresses for incoming connections:
+            https://clickhouse.com/docs/en/operations/server-configuration-parameters/settings/#server_configuration_parameters-listen_host
