+Dockerfile examples
+===================
+
+This directory contains example Dockerfiles that demonstrate how to use the image with a Dockerfile and `docker build`.
+
+For demonstration, we use an application code available at https://github.com/sclorg/nodejs-ex.git.
+
+Pull the source to the local machine first:
+```
+git clone https://github.com/sclorg/nodejs-ex.git app-src
+```
+
+Then, build a new image from a Dockerfile in this directory:
+```
+docker build -f Dockerfile -t node-app .
+```
+
+And run the resulting image with the final application:
+```
+docker run -ti --rm node-app
+```
+
