+## GitHub Actions for deploying to GitHub Pages
+
+A GitHub Action to deploy your static site to GitHub Pages with [Static Site Generators] (Hugo, MkDocs, Gatsby, GitBook, etc.)
+
+[Static Site Generators]: https://www.staticgen.com/
+
+
+
+## Getting started
+
+### (1) Add deploy Key
+
+1. Generate deploy key `ssh-keygen -t rsa -b 4096 -C "[email protected]" -f gh-pages -N ""`
+2. Go to "Settings > Deploy Keys" of repository.
+3. Add your public key within "Allow write access" option.
+4. Go to "Settings > Secrets" of repository.
+5. Add your private deploy key as `ACTIONS_DEPLOY_KEY`
+
+### (2) Create `main.workflow`
+
+An example with Hugo action.
