+> Port mapping must not be used with `network_mode: host`. Doing so causes a runtime error because `network_mode: host` already exposes container ports directly to the host network, so port mapping isn’t needed.

 #### Long syntax
 
 The long form syntax lets you configure additional fields that can't be
 expressed in the short form.
 
-- `target`: The container port
+- `target`: The container port.
 - `published`: The publicly exposed port. It is defined as a string and can be set as a range using syntax `start-end`. It means the actual port is assigned a remaining available port, within the set range.
-- `host_ip`: The Host IP mapping, unspecified means all network interfaces (`0.0.0.0`).
+- `host_ip`: The host IP mapping. If it is not set, it binds to all network interfaces (`0.0.0.0`).
 - `protocol`: The port protocol (`tcp` or `udp`). Defaults to `tcp`.
 - `app_protocol`: The application protocol (TCP/IP level 4 / OSI level 7) this port is used for. This is optional and can be used as a hint for Compose to offer richer behavior for protocols that it understands. Introduced in Docker Compose version [2.26.0](/manuals/compose/releases/release-notes.md#2260).
-- `mode`: `host`: For publishing a host port on each node, or `ingress` for a port to be load balanced. Defaults to `ingress`.
+- `mode`: Specifies how the port is published in a Swarm setup. If set to `host`, it publishes the port on every node in Swarm. If set to `ingress`, it allows load balancing across the nodes in Swarm. Defaults to `ingress`.
 - `name`: A human-readable name for the port, used to document it's usage within the service.
