 ## Usage
 
-```
-action "Update Docker Hub Repository Description" {
-  uses = "peter-evans/dockerhub-description@master"
-  secrets = ["DOCKERHUB_USERNAME", "DOCKERHUB_PASSWORD", "DOCKERHUB_REPOSITORY"]
-}
+```yml
+    - name: Docker Hub Description
+      uses: peter-evans/dockerhub-description@v2.0.0
+      env:
+        DOCKERHUB_USERNAME: ${{ secrets.DOCKERHUB_USERNAME }}
+        DOCKERHUB_PASSWORD: ${{ secrets.DOCKERHUB_PASSWORD }}
+        DOCKERHUB_REPOSITORY: peterevans/dockerhub-description
 ```
 
-#### Required secrets
+#### Required environment variables
 
-- `DOCKERHUB_USERNAME` - Docker Hub username
-- `DOCKERHUB_PASSWORD` - Docker Hub password
-- `DOCKERHUB_REPOSITORY` - The name of the Docker Hub repository to update. (This may also be an environment variable if not considered sensitive)
+- `DOCKERHUB_USERNAME` - Docker Hub username. If updating a Docker Hub repository belonging to an organization, this user must have `Admin` permissions for the repository.
+- `DOCKERHUB_PASSWORD` - Docker Hub password.
+- `DOCKERHUB_REPOSITORY` - The Docker Hub repository to update in the format `<namespace>/<name>`.
+
+Note that `DOCKERHUB_REPOSITORY` may also be passed as a secret if considered sensitive.
 
 #### Optionally specifying the file path
 
 The action assumes that there is a file called `README.md` located at the root of the repository.
 If this is not the case, the path can be overridden with an environment variable.
 
-```
-action "Update Docker Hub Repository Description" {
-  uses = "peter-evans/dockerhub-description@master"
-  secrets = ["DOCKERHUB_USERNAME", "DOCKERHUB_PASSWORD", "DOCKERHUB_REPOSITORY"]
-  env = {
-    README_FILEPATH = "./some-path/README.md"
-  }
-}
+```yml
+    - name: Docker Hub Description
+      uses: peter-evans/dockerhub-description@v2.0.0
+      env:
+        DOCKERHUB_USERNAME: ${{ secrets.DOCKERHUB_USERNAME }}
+        DOCKERHUB_PASSWORD: ${{ secrets.DOCKERHUB_PASSWORD }}
+        DOCKERHUB_REPOSITORY: peterevans/dockerhub-description
+        README_FILEPATH: ./some-path/README.md
 ```

 Updates the Docker Hub repository description whenever there is a `git push` to the `master` branch.

+docker run -v $PWD:/workspace \
+  -e DOCKERHUB_USERNAME='user1' \
