+## Creating and running a simple image (without Docker compose)
+
+Create the Dockerfile in the root of the project.
+
+Then build the image from root.
+
+```
+docker build -t image-name .
+```
+
+The image name is defined at this point, not pre-defined.
+
+If successful, run the image:
+
+```
+docker run --name your-container-name image-name
+```
+
+Again, the container-name is defined at the point of the `run` declaration.
