To write a new post, add a file in the _posts directory with the following
naming scheme:
YYYY-MM-DD-write-title-like-this.markdown
Look in _posts for examples. Then write markdown in that file. Commit and
push. If the post is any more than a couple of sentences long, or has
photos, etc. put four (4) new lines after the first paragraph to denote an
excerpt. This will keep the front page from getting to detailed.
See kramdown for markup help. (This is the particular parser we use here).
