+# Clickhouse
+
+## Getting Started
+
+```nix
+# In `perSystem.process-compose.<name>`
+{
+  services.clickhouse."clickhouse-1".enable = true;
+}
+```
+
+## Tips & Tricks
+
+### Change the HTTP default port
+
+Clickhouse has [HTTP Interface](https://clickhouse.com/docs/en/interfaces/http) that is enabled by default on port 8123. To change the default port, use the `extraConfig` option:
+
+```nix
+{
+  services.clickhouse."clickhouse-1" = {
+    enable = true;
+    extraConfig = ''
+      http_port: 9050
+    '';
+  };
+}
+```
