 ## Usage
 
-```
+```yml
-action "Docker Hub Description" {
+    - name: Docker Hub Description
-  uses = "peter-evans/dockerhub-description@v1.0.0"
+      uses: peter-evans/dockerhub-description@v2.0.0
-  secrets = ["DOCKERHUB_USERNAME", "DOCKERHUB_PASSWORD", "DOCKERHUB_REPOSITORY"]
+      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_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_PASSWORD` - Docker Hub password.
-- `DOCKERHUB_REPOSITORY` - The name of the Docker Hub repository to update. The action combines this with the username to locate the repository. i.e. `username/repository`
+- `DOCKERHUB_REPOSITORY` - The Docker Hub repository to update in the format `<namespace>/<name>`.
 
-Note that `DOCKERHUB_USERNAME` and `DOCKERHUB_REPOSITORY` may also be environment variables if not considered sensitive.
+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.
 
-```
+```yml
-action "Docker Hub Description" {
+    - name: Docker Hub Description
-  uses = "peter-evans/dockerhub-description@v1.0.0"
+      uses: peter-evans/dockerhub-description@v2.0.0
-  secrets = ["DOCKERHUB_USERNAME", "DOCKERHUB_PASSWORD", "DOCKERHUB_REPOSITORY"]
+      env:
-  env = {
+        DOCKERHUB_USERNAME: ${{ secrets.DOCKERHUB_USERNAME }}
-    README_FILEPATH = "./some-path/README.md"
+        DOCKERHUB_PASSWORD: ${{ secrets.DOCKERHUB_PASSWORD }}
-  }
+        DOCKERHUB_REPOSITORY: peterevans/dockerhub-description
-}
+        README_FILEPATH: ./some-path/README.md
 ```
 
 #### Examples
 
 Updates the Docker Hub repository description whenever there is a `git push` to the `master` branch.
-```
+```yml
-workflow "Update Docker Hub Description" {
+name: Update Docker Hub Description
-  resolves = ["Docker Hub Description"]
+on:
-  on = "push"
+  push:

-  secrets = ["DOCKERHUB_USERNAME", "DOCKERHUB_PASSWORD", "DOCKERHUB_REPOSITORY"]

-}
+        DOCKERHUB_PASSWORD: ${{ secrets.DOCKERHUB_PASSWORD }}
+        DOCKERHUB_REPOSITORY: peterevans/dockerhub-description
 ```
 
 Updates the Docker Hub repository description whenever a new release is created.
+```yml
+name: Update Docker Hub Description
+on: release
+jobs:
+  dockerHubDescription:
+    runs-on: ubuntu-latest
+    steps:
