To set up a static blog in Github Pages using the Racket package Frog, you need to do the following:

• download and install Racket (duh!)
• install Frog with raco:

$ raco install frog

• create a folder and initialize a Frog project there:

$ mkdir new-blog
$ cd new-blog
$ raco frog --init

• customize the .frogrc file. Set at least scheme/host to https://your-username.github.io, and title & author to whatever you want.

• add some content of your own:

$ raco frog -n "New post"
# ... output says something like:
~/new-blog/_src/posts/2016-10-03-new-post.md
# ... edit that file with your preferred editor ...
when you are finished editing, preview your glorious site with

$ raco frog -bp

• initialize an empty Git repository on the project folder, and tell git to ignore the Frog machinery and your source directory

$ git init .
$ cat << EOF > .gitignore
/.frog/
/.frogrc
/_src/
EOF

• commit everything, except for what we just ignored

$ git add .
$ git commit

• on github.com, create a new repository with the name your-username.github.io. Once created, add it as a remote to your local repo, and push your local master to it.

$ git remote add origin <your new repo>
$ git push -u origin master

• after some seconds, your new blog should be available as http://your-username.github.io

Now, each time that you want to add a new post, it’s just a matter of

$ raco frog -n "Another post"
# ... edit that post ...
$ raco frog -b
$ git add .
$ git commit -a
$ git push
