-# Installation
+## Project Status
+
+gemget is in maintenance mode. See my [blog post](https://www.makeworld.space/2023/08/bye_gemini.html) for details.
+
+## Installation
 Install a binary of the most recent release from the [releases page](https://github.com/makeworld-the-better-one/gemget/releases/). On Unix-based systems you will have to make the file executable with `chmod +x <filename>`. You can rename the file to just `gemget` for easy access, and move it to `/usr/local/bin/`.
 
 If you have Go installed, you can also install it using the Makefile. Make sure to use GNU Make.
