+    echo "Usage: $0 <message>"
+    exit
+fi

+     -H 'Content-Type: application/json' \
+     --data "{\"token\":\"$TOKEN\",\"message\":\"$MESSAGE\"}" \
+     --connect-timeout 10 --retry 3
+```
+
+This script requires [cURL](https://curl.se/), which is shipped with almost all linux distros by default.
+Place your API token in `$TOKEN`, then execute the script like this:
+
+```shell
+./kimikuri.sh "Hello, world!"
+```
