+To install:
+1. put it wherever you want and just add it to path
+2. make sure you modify `make_globals()` and `build_entries()` in the script to

 To use:
-1. write your post in .gmi format  
-   the script will display all posts starting with a number in reverse
-   alphabetical order, so I recommend naming your post in the format

+   `YYYY-MM-DD-title-here.gmi` so you get them sorted nicely in reverse
+   chronological order.
+3. make sure you're in your gemlog directory then run `gemlog.sh` to build the
+   index page and the atom feed
+4. if you want your atom feed to be accessible over the web as well as gemini,
+   symlink the atom.xml file to your web server directory
