+# Configuration structure
+
+All configuration options defined in one YAML file, ex `config.yaml`, that has some sections, represented below.
+
+## *Server*
+
+```yaml
+Server:
+  bind_address: '0.0.0.0'
+  port: 8800
+  refresh_time: 20
+```
+**`bind address`** - Ipv4 or DSN for binding http server with metrics
+
+**`port`** - Port for http server
+
+**`refresh_time`** (seconds) - Time of updating data in prometheus endpoint. This is independent from collectors of these metrics
+
+## *Global*
+```yaml
+Global:
+  unit: 'ms'
+```
+**`unit`** - Unit of Round-Trip-Time (RTT) in collected metrics
+
+## *Local*
+```yaml
+Local:
+  src_addr: '0.0.0.0' 
+  timeout: 1
+  ttl: 64
+  size: 56
