+# Archive imgur images
+
+A set of scripts for finding and downloading imgur images linked in messages.
+
+Since imgur announced to remove anonymously posted content soon, I decided to
+write some scripts to download and preserve all imgur images ever posted to
+euphoria. Run at your own risk :P
+
+## Usage
+
+First, install [requests](https://pypi.org/project/requests/) or use the flake
+with `nix develop`. Then execute the following commands:
+
+```
+$ cove export -o - -f json-stream -a | ./find_images.py
+$ ./download_images.py
+```
+
+For more info and available arguments, consult `cove export --help`,
+`./find_images.py --help`, and `./download_images.py --help`.
