-A GitHub Action to deploy your static site to GitHub Pages with [Static Site Generators] (Hugo, MkDocs, Gatsby, GitBook, etc.)
+This is a **GitHub Action** to deploy your static files to **GitHub Pages**.
+This deploy action can be combined simply and freely with [Static Site Generators]. (Hugo, MkDocs, Gatsby, GitBook, etc.)
 
 [Static Site Generators]: https://www.staticgen.com/

+
+
+
+## Options
+
+### ⭐️ Pull action image from Docker Hub
+
+You can pull a public docker image from Docker Hub.
+By pulling docker images, you can reduce the overall execution time of your workflow. In addition, `latest` tag is provided.
+
+```diff
+- uses: peaceiris/actions-gh-pages@v2.5.0
++ uses: docker://peaceiris/gh-pages:v2.5.0
+```
+
+- [peaceiris/gh-pages - Docker Hub](https://hub.docker.com/r/peaceiris/gh-pages)
+
+### ⭐️ `PERSONAL_TOKEN`
+
+[Generate a personal access token (`repo`)](https://github.com/settings/tokens) and add it to Secrets as `PERSONAL_TOKEN`, it works as well as `ACTIONS_DEPLOY_KEY`.
+
+```diff
+- ACTIONS_DEPLOY_KEY: ${{ secrets.ACTIONS_DEPLOY_KEY }}
++ PERSONAL_TOKEN: ${{ secrets.PERSONAL_TOKEN }}
+```
+
+### ⭐️ `GITHUB_TOKEN`
+
+> ⚠️ **NOTES**: `GITHUB_TOKEN` works only on a **private** repository.
+>
+> This action supports `GITHUB_TOKEN` but it has some problems to deploy to GitHub Pages. GitHub team is investigating that. See [Issue #9]
+
+[Issue #9]: https://github.com/peaceiris/actions-gh-pages/issues/9
+
+```diff
+- ACTIONS_DEPLOY_KEY: ${{ secrets.ACTIONS_DEPLOY_KEY }}
++ GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+```
+
+### ⭐️ Suppressing empty commits
+
+By default, a commit will always be generated and pushed to the `PUBLISH_BRANCH`, even if nothing changed. If you want to suppress this behavior, set the optional parameter `emptyCommits` to `false`. cf. [Issue #21]
+
+[Issue #21]: https://github.com/peaceiris/actions-gh-pages/issues/21
+
+For example:
+
+```yaml
+- name: Deploy
+  uses: peaceiris/actions-gh-pages@v2.5.0
+  env:
+    ACTIONS_DEPLOY_KEY: ${{ secrets.ACTIONS_DEPLOY_KEY }}
+    PUBLISH_BRANCH: gh-pages
+    PUBLISH_DIR: ./public
+  with:
+    emptyCommits: false
+```
+
+### ⭐️ Keeping existing files
+
+By default, existing files in the publish branch are removed before adding the ones from publish dir. If you want the action to add new files but leave existing ones untouched, set the optional parameter `keepFiles` to `true`.
+
+For example:
+
+```yaml
+- name: Deploy
+  uses: peaceiris/actions-gh-pages@v2.5.0
+  env:
+    ACTIONS_DEPLOY_KEY: ${{ secrets.ACTIONS_DEPLOY_KEY }}
+    PUBLISH_BRANCH: gh-pages
+    PUBLISH_DIR: ./public
+  with:
+    keepFiles: true
+```
+
+### ⭐️ Deploy to external repository
+
+By default, your files are published to the repository which is running this action.
+If you want to publish to another repository on GitHub, set the environment variable `EXTERNAL_REPOSITORY` to `<username>/<external-repository>`.
+This option is available from `v2.5.0`.
+
+For example:
+
+```yaml
+- name: Deploy
+  uses: peaceiris/actions-gh-pages@v2.5.0
+  env:
+    ACTIONS_DEPLOY_KEY: ${{ secrets.ACTIONS_DEPLOY_KEY }}
+    EXTERNAL_REPOSITORY: username/external-repository
+    PUBLISH_BRANCH: gh-pages
+    PUBLISH_DIR: ./public
+```
+
+You can use `ACTIONS_DEPLOY_KEY` or `PERSONAL_TOKEN`.
+When you use `ACTIONS_DEPLOY_KEY`, set your private key to the repository which includes this action and set your public key to your external repository.
+
+Be careful, `GITHUB_TOKEN` has no permission to access to external repositories.
+
+### ⭐️ Script mode
+
+From `v2.5.0`, we can run this action as a shell script.
+There is no Docker build or pull step, so it will start immediately.
+
+- `ACTIONS_DEPLOY_KEY` requires `SCRIPT_MODE: true`
+- `*_TOKEN` do not require `SCRIPT_MODE`
+
+```yaml
+- name: Deploy
+  env:
+    ACTIONS_DEPLOY_KEY: ${{ secrets.ACTIONS_DEPLOY_KEY }}
+    PUBLISH_BRANCH: gh-pages
+    PUBLISH_DIR: ./public
+    SCRIPT_MODE: true
+  run: |
+    wget https://raw.githubusercontent.com/peaceiris/actions-gh-pages/v2.5.0/entrypoint.sh
+    bash ./entrypoint.sh
+```
+
+<div align="right">

+</div>
+
+
+
+## Tips and FAQ
+
+### ⭐️ Use the latest and specific release
+
+We recommend you to use the latest and specific release of this action for stable CI/CD.
+It is useful to watch this repository (release only) to check the [latest release] of this action.
+
+[latest release]: https://github.com/peaceiris/actions-gh-pages/releases
+
+### ⭐️ How to add `CNAME`
+
+Most of the Static Site Generators support `CNAME` as a static file.
+
+- [Use a Custom Domain | Hugo](https://gohugo.io/hosting-and-deployment/hosting-on-github/#use-a-custom-domain)
+- [Using the Static folder | GatsbyJS](https://www.gatsbyjs.org/docs/static-folder/)
+
+The same may be said of other files (`.nojekyll`, `BingSiteAuth.xml`, `robots.txt`, etc.). It is better to manage those files by Static Site Generators.
+
+Does not your static site generator deal with the static files? No problem, you can add the file like the following.
+
+```yaml
+- name: Build
+  run: |
+    buildcommand
+    cp ./path/to/CNAME ./public/CNAME
+
+- name: Deploy
+```
+
+### ⭐️ Deployment completed but you cannot read
+
+Does your `PUBLISH_DIR` contain files or directories that name starts with an underscore? (`_modules`, `_sources` and `_next`, etc.)
+GitHub Pages does not read those by default.
+Please add `.nojekyll` file to `PUBLISH_DIR`.
+
+- [Bypassing Jekyll on GitHub Pages - The GitHub Blog](https://github.blog/2009-12-29-bypassing-jekyll-on-github-pages/)
+
+> It is now possible to completely bypass Jekyll processing on GitHub Pages by creating a file named `.nojekyll` in the root of your pages repo and pushing it to GitHub. This should only be necessary if your site uses files or directories that start with underscores since Jekyll considers these to be special resources and does not copy them to the final site.
+
+Does not your static site generator deal with the static files? No problem, you can add the file like the following.
+
+```yaml
+- name: Build
+  run: |
+    buildcommand
+    touch ./public/.nojekyll
