 - **repo**: repository to deploy to. Must be readable and writable. The default of "origin" will not work on Travis CI, since it uses the read-only git protocol. In that case, it is recommended to store a [GitHub token](https://help.github.com/articles/creating-an-access-token-for-command-line-use) in a [secure environment variable](http://about.travis-ci.org/docs/user/build-configuration/#Secure-environment-variables) and use it in an HTTPS URL like this: <code>repo=https://$GITHUB_TOKEN@github.com/<i>user</i>/<i>repo</i>.git</code>
 
 ## setup
-Do this once to set up a deploy branch if you don't already have one. This could be implemented in the script, but I don’t feel like doing it. Replace "dist" with your deploy_directory and "gh-pages" with your deploy_branch.
-
-1. `git --work-tree dist checkout --orphan gh-pages`
-	- this will disconnect the gh-pages branch’s history from the current commit
-	- in my app, the project root and dist had no files in common. If yours do, be careful if you don’t want to overwrite any existing files in dist
-2. `git --work-tree dist rm -r "*"`
-	- remove the source files we just checked out; these aren’t the files we’re looking for
-	- the quotes are required to prevent the shell from globbing in the current directory; we want git to glob in dist
-3. `git --work-tree dist add --all`
-4. `git --work-tree dist commit -m "initial publish"`
-5. `git push origin gh-pages`
-6. `git symbolic-ref HEAD refs/heads/master && git reset --mixed`
-	- switch back to master branch
+Ensure configuration variables are correct in `deploy.sh` and run `./deploy.sh -s`
 
 ## run
 Do this every time you want to deploy, or have your CI server do it.
