 # Docker Run Action
 
-- run a specific step in docker.
-- run an image built by a previous step.
-- See https://github.com/addnab/docker-run-action/blob/main/action.yml for all the available inputs.
+This action targets a very specific use-case that is not currently supported by Github Workflows. This action gives you the capability to run built containers.
 
-## Examples
+Docker already supports running commands inside a docker image. See [jobs.<jobs_id>.container](https://help.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idcontainer). But it doesn't give you a clean way to run an image from a private repo or an image built on a previous step.
 
-#### Typical Use Case
+### Example Usage
 
+#### Standard use-case
 ```yaml
-- name: Checkout 
-  uses: actions/checkout@v2 # Required to mount the Github Workspace to a volume 
-- uses: addnab/docker-run-action@v3
-  with:
-    username: ${{ secrets.DOCKER_USERNAME }}
-    password: ${{ secrets.DOCKER_PASSWORD }}
-    registry: gcr.io
-    image: private-image:latest
-    options: -v ${{ github.workspace }}:/work -e ABC=123
-    run: |
-      echo "Running Script"
-      /work/run-script
-```
-
-#### run a privately-owned image
-```yaml
-- uses: addnab/docker-run-action@v3
-  with:
-    username: ${{ secrets.DOCKER_USERNAME }}
-    password: ${{ secrets.DOCKER_PASSWORD }}
-    registry: gcr.io
-    image: test-image:latest
-    run: echo "hello world"
-```
-
-#### run an image built by a previous step
-```yaml
-- uses: docker/build-push-action@v2
-  with:
-    tags: test-image:latest
-    push: false
-- uses: addnab/docker-run-action@v3
-  with:
-    image: test-image:latest
-    run: echo "hello world"
-```
-
-
-#### use a specific shell (default: sh). 
-*Note: The shell must be installed in the container*
-```yaml
-- uses: addnab/docker-run-action@v3
+- uses: addnab/docker-run-action@v1
   with:
     image: docker:latest
-    shell: bash
-    run: |
-      echo "first line"
-      echo "second line"
+    command: echo "hello world"
+```
+
+### Supported Inputs

+  image:
+    description: 'Image'
+    required: true
+  options:
