+Atmosphere generates dynamic ANSI-powered weather for ASCII landscapes. It's
+based on ~iajrz's `climate` program that generates randomized weather prompts.
+
+Using that generated weather, Atmosphere grabs an ASCII landscape and some
+specially-made metadata about it and paints weather over the top. Time of day,
+cloudiness, fogginess, windiness, and raininess are all supported.
+
+Atmosphere periodically polls for weather changes, and if the weather has been
+updated the scene will transition out and back in with the new weather.
+
+## Plans/ideas
+
+Maybe periodically cycle through different scenes, not just when the weather
+has been updated? Would also make like "close up" scenes where the sky isn't
+visible feasible if it'll just transition out after a few minutes.
+
+## Installation
+
+`go get git.tilde.town/diff/Atmosphere`
+
+## Usage
+
+Just run the compiled executable file.
