+## freebox
+
+Scripts to interact with a Freebox OS using the official API.
+
+### get_token.sh
+
+Registers a new application with the Freebox and requests authorisation.  
+After approving the request on the Freebox, the generated app token is saved to `freebox_app_token.txt`.  
+By default generates a token for the `APP_ID` `fr.bash.reboot`  
+curl and jq are needed.
+
+### freebox_reboot.sh
+
+Authenticates using the app token from `freebox_app_token.txt` and sends a reboot request to the Freebox over the HTTPS Freebox OS API.  
+Requires the Freebox ECC Root CA certificate (`freebox_ecc_root_ca.pem`) to be in the same directory as the script.  
+By default the token should be for the `APP_ID` `fr.bash.reboot`.  
+curl, openssl and jq are needed.  
+By default an app is not allowed to reboot the freebox, to allow it, go in "paramètre de la freebox -> gestion des accès -> application", then modify the permissions for your app and check "modification des réglages de la Freebox".
