 ### Installation
 If you are using [Nix](https://nixos.org/) with [flakes enabled](https://nixos.wiki/wiki/Flakes#Enable_flakes), you can directly run the latest version of this code without any installation:
 ```sh
-nix run git+https://gitlab.irit.fr/poquet/lflex-celcat-survival\?ref=main#fetch-ics -- request-file.csv -o out.ics
+nix run git+https://gitlab.irit.fr/poquet/millian/lflex-celcat-survival\?ref=main#fetch-celcat -- request-file.csv credentials.json --ics /tmp/calendar.ics
 ```
 
 If you are using [Nix](https://nixos.org/), you can enter a shell where the program is available by typing this command:
 ```sh
-nix-shell https://gitlab.irit.fr/poquet/lflex-celcat-survival/-/archive/main/lflex-celcat-survival-main.tar.gz -A user-shell
-# then, inside the temporary shell: fetch-ics request-file.csv -o out.ics
+nix-shell https://gitlab.irit.fr/poquet/millian/lflex-celcat-survival/-/archive/main/lflex-celcat-survival-main.tar.gz -A user-shell
+# then, inside the temporary shell: fetch-celcat request-file.csv credentials.json --ics /tmp/calendar.ics
 ```
 
 If you are using [Nix](https://nixos.org/) but want to install this software instead:
 ```sh
-nix-env -f https://gitlab.irit.fr/poquet/lflex-celcat-survival/-/archive/main/lflex-celcat-survival-main.tar.gz -iA lflex_celcat_survival
-# then, whenever you want: fetch-ics request-file.csv -o out.ics
+nix-env -f https://gitlab.irit.fr/poquet/millian/lflex-celcat-survival/-/archive/main/lflex-celcat-survival-main.tar.gz -iA lflex_celcat_survival
+# then, whenever you want: fetch-celcat request-file.csv credentials.json --ics /tmp/calendar.ics
 ```
 
 If you are not using [Nix](https://nixos.org/), you can do a local installation via [pip](https://pip.pypa.io/en/stable/):
 ```sh
-pip install git+https://gitlab.irit.fr/poquet/lflex-celcat-survival
-# then, whenever you want: fetch-ics request-file.csv -o out.ics
+pip install git+https://gitlab.irit.fr/poquet/millian/lflex-celcat-survival
+# then, whenever you want: fetch-celcat request-file.csv credentials.json --ics /tmp/calendar.ics
