+# Fediverse Nose Ears bot
+
+Posts the [Nose Ears](https://wuzzy.neocities.org/) comics to the
+fediverse. It supports comic titles, images and alt texts. 
+
+## Configuration
+
+To configure this bot, customize the first lines in the `noseears.py`
+script to your needs, such as by setting the `instance` varible and
+the `datadir` and `credfile` variables to indicate the position where
+the bot should store its data and the credentials file
+respectively. The credentials file can be generated using the
+`mastodon.log_in` method.
+
+## Usage
+
+When supplied with no arguments, `noseears.py` tries to fetch the
+latest nose ears comic. When supplied with a number as an argument, it
+tries to fetch the comic with said number, and if "random" is passed
+as an argument, it tries to fetch a random comic.
