+## Additions
+
+* New `command` input
+    * This allows you to specify the Wrangler command you would like to run.
+    For example, if you want to publish the production version of your Worker you may run `publish --env=production`.
+    * This opens up other possibilities too like publishing a Pages project: `pages publish <directory> --project-name=<name>`.
+* New `accountId` input
+  * This allows you to specify your account ID.
+
+## Removals
+
+* Removed `publish` input (refer to [Breaking changes](#breaking-changes)).
+
+## Changes
+
+-- no changes --
+
+## __Breaking changes__
+
+* `publish` has been removed.
+  * You should instead do `command: publish`.

 # Wrangler GitHub Action
 
-✨ Zero-config [Cloudflare Workers](https://workers.cloudflare.com) deployment using [Wrangler](https://github.com/cloudflare/wrangler) and [GitHub Actions](https://github.com/actions)
+Easy-to-use GitHub Action to use [Wrangler](https://developers.cloudflare.com/workers/cli-wrangler/). Makes deploying Workers, Pages or modifying R2 easy to do.
+
+[Refer to Changelog for more information](CHANGELOG.md).
 
 ## Usage
 
-Add `wrangler-action` to the workflow for your Workers application. The below example will publish your application on pushes to the `master` branch:
+Add `wrangler-action` to the workflow for your Workers/Pages application. The below example will publish a Worker on a `git push` to the `main` branch:
+
+```yaml
+name: Deploy
+
+on:
+  push:
+    branches:
+      - main
+
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    name: Deploy
+    steps:
+      - uses: actions/checkout@v2
+      - name: Publish
+        uses: cloudflare/wrangler-action@2.0.0
+        with:
+          apiToken: ${{ secrets.CF_API_TOKEN }}
+```
+
+## Authentication
+
+You'll need to configure Wrangler using GitHub's Secrets feature - go to "Settings -> Secrets" and add your Cloudflare API token (for help finding this, see the [Workers documentation](https://developers.cloudflare.com/workers/quickstart/#api-token)). Your API token is encrypted by GitHub, and the action won't print it into logs, so it should be safe!
+
+With your API token set as a secret for your repository, pass it to the action in the `with` block of your workflow. Below, I've set the secret name to `CF_API_TOKEN`:
+
+```yaml
+jobs:
+  deploy:
+    name: Deploy
+    steps:
+      uses: cloudflare/wrangler-action@2.0.0
+      with:
+        apiToken: ${{ secrets.CF_API_TOKEN }}
+```
+
+`wrangler-action` also supports using your [global API key and email](https://developers.cloudflare.com/workers/quickstart/#global-api-key) as an authentication method, although API tokens are preferred. Pass in `apiKey` and `email` to the GitHub Action to use this method:
+
+```yaml
+jobs:
+  deploy:
+    name: Deploy
+    steps:
+      uses: cloudflare/wrangler-action@2.0.0
+      with:
+        apiKey: ${{ secrets.CF_API_KEY }}
+        email: ${{ secrets.CF_EMAIL }}
+```
+
+## Configuration
+
+If you need to install a specific version of Wrangler to use for deployment, you can also pass the input `wranglerVersion` to install a specific version of Wrangler from NPM. This should be a [SemVer](https://semver.org/)-style version number, such as `1.6.0`:
+
+```yaml
+jobs:
+  deploy:
+    steps:
+      uses: cloudflare/wrangler-action@2.0.0
+      with:
+        apiToken: ${{ secrets.CF_API_TOKEN }}
+        wranglerVersion: '1.6.0'
+```
+
+Optionally, you can also pass a `workingDirectory` key to the action. This will allow you to specify a subdirectory of the repo to run the Wrangler command from.
+
+```yaml
+jobs:
+  deploy:
+    steps:
+      uses: cloudflare/wrangler-action@2.0.0
+      with:
+        apiToken: ${{ secrets.CF_API_TOKEN }}
+        workingDirectory: 'subfoldername'
+```
+
+[Worker secrets](https://developers.cloudflare.com/workers/tooling/wrangler/secrets/) can be optionally passed as a new line deliminated string of names in `secrets`.  Each secret name must match an environment variable name specified in the `env` attribute.  Creates or replaces the value for the Worker secret using the `wrangler secret put` command.
+
+```yaml
+jobs:
+  deploy:
+    steps:
+      uses: cloudflare/wrangler-action@2.0.0
+      with:
+        apiToken: ${{ secrets.CF_API_TOKEN }}
+        secrets: |
+            SECRET1
+            SECRET2
+      env:
+        SECRET1: ${{ secrets.SECRET1 }}
+        SECRET2: ${{ secrets.SECRET2 }}
+```
+
+If you need to run additional shell commands before or after your command, you can specify them as input to `preCommands` (before `publish`) or `postCommands` (after `publish`). These can include additional `wrangler` commands (that is, `whoami`, `kv:key put`) or any other commands available inside the `wrangler-action` context.
+
+```yaml
+jobs:
+  deploy:
+    steps:
+      uses: cloudflare/wrangler-action@2.0.0
+      with:
+        apiToken: ${{ secrets.CF_API_TOKEN }}
+        preCommands: echo "*** pre command ***"
+        postCommands: |
+          echo "*** post commands ***"
+          wrangler kv:key put --binding=MY_KV key2 value2
+          echo "******"
+```
+
+You can use the `command` option to do specific actions such as running `wrangler whoami` against your project:
+
+```yaml
+jobs:
+  deploy:
+    steps:
+      uses: cloudflare/wrangler-action@2.0.0
+      with:
+        apiToken: ${{ secrets.CF_API_TOKEN }}
+        command: whoami
+```
+
+## Use cases
+
+### Deploy when commits are merged to main
+
+The above workflow examples have already shown how to run `wrangler-action` when new commits are merged to the main branch. For most developers, this workflow will easily replace manual deploys and be a great first integration step with `wrangler-action`:
 
 ```yaml
 on:
   push:
     branches:
-    - master
+      - main
 
 jobs:
   deploy:
     runs-on: ubuntu-latest
     name: Deploy
     steps:
-    - uses: actions/checkout@master
-    - name: Publish
-      uses: signalnerve/wrangler-action@0.1.0
-      with:
-        apiKey: ${{ secrets.CLOUDFLARE_API_KEY }}
-        email: ${{ secrets.CLOUDFLARE_EMAIL }}
+      - uses: actions/checkout@v3
+      - name: Publish
+        uses: cloudflare/wrangler-action@2.0.0
+        with:
+          apiToken: ${{ secrets.CF_API_TOKEN }}
 ```
 
-## Configuration
+Note that there are a number of possible events, like `push`, that can be used to trigger a workflow. For more details on the events available, refer to the [GitHub Actions documentation](https://help.github.com/en/articles/workflow-syntax-for-github-actions#on).
 
-You'll need to configure Wrangler using GitHub's Secrets feature - go to "Settings -> Secrets" and add your Cloudflare API key and email (for help finding these, see the [Workers documentation](https://developers.cloudflare.com/workers/quickstart/#finding-your-cloudflare-api-keys)). Your API key and email are encrypted by GitHub, and the action won't print them into logs, so they should be safe!
+### Deploy your Pages site (production & preview)
 
-With your API key and email set as secrets for your repository, pass them to the action in the `with` block of your workflow:
+If you want to deploy your Pages project with GitHub Actions rather than the built-in continous integration (CI), then this is a great way to do it. Wrangler 2 will populate the commit message and branch for you. You only need to pass the project name. If a push to a non-production branch is done, it will publish as a preview deployment:
 
 ```yaml
+on: [push]
+
 jobs:
   deploy:
+    runs-on: ubuntu-latest
     name: Deploy
     steps:
-      uses: signalnerve/wrangler-action@0.1.0
-      with:
-        apiKey: ${{ secrets.CLOUDFLARE_API_KEY }}
-        email: ${{ secrets.CLOUDFLARE_EMAIL }}
+      - uses: actions/checkout@v3
+      - name: Publish
+        uses: cloudflare/wrangler-action@2.0.0
+        with:
+          apiToken: ${{ secrets.CF_API_TOKEN }}
+          accountId: ${{ secrets.CF_ACCOUNT_ID }}
+          command: pages publish --project-name=example
 ```
 
-Optionally, you can also pass an `environment` key to the action. If you're using Wrangler's [environments](https://github.com/cloudflare/wrangler/blob/master/docs/content/environments.md) feature, you can customize _where_ the action deploys to by passing the matching environment in the `with` block of your workflow:
+### Deploying on a schedule
+
+If you would like to deploy your Workers application on a recurring basis – for example, every hour, or daily – the `schedule` trigger allows you to use cron syntax to define a workflow schedule. The below example will deploy at the beginning of every hour:
 
 ```yaml
+on:
+  schedule:
+    - cron: '0 * * * *'
+
 jobs:
   deploy:
-    # ... previous configuration ...
+    runs-on: ubuntu-latest
+    name: Deploy
     steps:
-      uses: signalnerve/wrangler-action@0.1.0
-      with:
-        # ... api key and email ...
-        environment: "production"
+      - uses: actions/checkout@v3
+      - name: Publish app
+        uses: cloudflare/wrangler-action@2.0.0
+        with:
+          apiToken: ${{ secrets.CF_API_TOKEN }}
 ```
 
+If you need help defining the correct cron syntax, check out [crontab.guru](https://crontab.guru/), which provides a friendly user interface for validating your cron schedule.
+
+### Manually triggering a deployment
+
+If you need to trigger a workflow at-will, you can use GitHub's `workflow_dispatch` [event](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#workflow_dispatch) in your workflow file. By setting your workflow to trigger on that event, you will be able to deploy your application via the GitHub UI. The UI also accepts inputs that can be used to configure the action:
+
+```yaml
+on:
+  workflow_dispatch:
+    inputs:
+      environment:
+        description: 'Choose an environment to deploy to: <dev|staging|prod>'
+        required: true
+        default: 'dev'
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    name: Deploy
+    steps:
+      - uses: actions/checkout@v3
+      - name: Publish app
+        uses: cloudflare/wrangler-action@2.0.0
+        with:
+          apiToken: ${{ secrets.CF_API_TOKEN }}
+          command: publish --env ${{ github.event.inputs.environment }}
+```
+
+For more advanced usage or to programmatically trigger the workflow from scripts, refer to [the GitHub documentation](https://docs.github.com/en/rest/reference/actions#create-a-workflow-dispatch-event) for making API calls.

 ## Troubleshooting
 
-This action is in beta, and I'm looking for folks to use it! If something goes wrong, please file an issue! That being said, there's a couple things you should know:
-
 ### "I just started using Workers/Wrangler and I don't know what this is!"
 
-No problem! Check out the [Quick Start guide](https://developers.cloudflare.com/workers/quickstart) in our docs to get started. Once you have a Workers application, you may want to set it up to automatically deploy from GitHub whenever you change your project. That's where this action comes in - nice!
+Refer to the [Quick Start guide](https://developers.cloudflare.com/workers/quickstart) to get started. Once you have a Workers application, you may want to set it up to automatically deploy from GitHub whenever you change your project.
 
-### "I'm trying to deploy my static site but it isn't working!"
+### "[ERROR] No account id found, quitting.."
 
-To deploy static sites and frontend applications to Workers, check out the documentation for [Workers Sites](https://developers.cloudflare.com/workers/sites).
-
-Note that this action makes no assumptions about _how_ your project is built! **If you need to run a pre-publish step, like building your application, you need to specify a build step in your Workflow.** For instance, if I have an NPM command called `build`, my workflow TOML might resemble the following:
+You will need to add `account_id = ""` in your `wrangler.toml` file or set `accountId` in this GitHub Action.
