+## Using the scripts in Docker images
+
+You can download the scripts on the fly, like this:
+
+```Dockerfile
+ADD https://raw.githubusercontent.com/concrete5/cli/master/c5 /usr/bin/
+
+RUN chmod +x /usr/bin/c5
+```
+
+You can also copy them from a Docker image, so that your build process doesn't have to download the scripts every time you need them:
+
+```Dockerfile
+COPY --from=concrete5/cli /usr/bin/c5 /usr/bin/
+```
