+# Running PCP using containers
+
+You can run `pcp` using container orchestrators
+
+* Docker
+* podman
+* [TODO] Kubernetes
+
+## Building container image using docker/podman
+
+
+```sh
+    # Build the pcp container
+    docker build -t pcp .
+```
+
+## Using pcp container
+
+You can run the container as is:
+
+```sh
+    # Use the container using the default site
+    docker run --rm -ti -p 3000:3000 pcp
+
+    # Mount your site in the container. Once it starts, you can edit files and refresh.
+    docker run --rm -ti -p 3000:3000 -v examples/netdava-test/public:/usr/share/pcp-site pcp
+```
+
+You can build a custom container from pcp with your site.
+
+```sh
+
+cat > mysite.dockerfile << EOF
+FROM pcp:latest
+COPY my-webiste /usr/share/pcp-site
+EOF
+
+# Build the custom image
+docker build -t my-pcp-site:latest -f mysite.dockerfile .
+# Run your website
+
+docker run --name my-pcp-site -p 3000:3000 my-pcp-site:latest
+```
