+# Docker Usage
+
+This repository includes Docker support for building and running the various projects.
+
+## Building a Docker Image
+
+To build a Docker image for a specific project, use the following command from the root directory:
+
+```bash
+# Build image for the image filter project
+docker build --build-arg PROJECT_PATH=src/project/image-filter-udagram-app -t udacity-image-filter .
+
+# Build image for microservices frontend
+docker build --build-arg PROJECT_PATH=src/project/c2-microservices-v1/udacity-c2-frontend -t udacity-c2-frontend .
+
+# Build image for microservices REST API feed service
+docker build --build-arg PROJECT_PATH=src/project/c2-microservices-v1/udacity-c2-restapi-feed -t udacity-c2-restapi-feed .
+```
+
+## Running a Docker Container
+
+After building an image, run it with:
+
+```bash
+docker run -p 8080:8080 udacity-image-filter
+```
+
+## GitHub Actions
+
+The repository includes GitHub Actions workflows that automatically build and publish Docker images to GitHub Container Registry when code is pushed to main branches.
+
+### Available Images
