-communication.
+This project, hosted on
+[git.cryptic.systems](https://git.cryptic.systems/volker.raschek/network-tools),
+contains only files to build to container image. The container image contains
+network tools to analyse or monitor network communication. This can be helpful
+in a containerized environment.
+
+## Usage
+
+To use this image execute the following command.
+
+```bash
+$ docker run \
+    --rm \
+    volkerraschek/network-tools:latest \
+      bash
+```
