-# key-emojipack-generator
+Janky Python script to generate the requisite meta.json file to make an emoji pack that can be imported by a *key instance.
 
-Procedurally generate a meta.json file for importing a folder of emojis on a *key instance
\ No newline at end of file
+# Usage
+
+Provide the script with a directory and it will generate a meta.json file listing every PNG/JPG/GIF/WEBP file, extrapolating the emoji name from the filename, and the category name from the directory name.
+
+- Pass `--host` to optionally customize the hostname used as the `host` property.
+- Pass `-p` to print the JSON to stdout instead of saving it.
