+**It4Innovations participating in DICE. DICE using iRods software**
+
+The integrated Rule-Oriented Data System (iRODS) is open source data management software used by research organizations and government agencies worldwide. iRODS is released as a production-level distribution aimed at deployment in mission critical environments. It virtualizes data storage resources, so users can take control of their data, regardless of where and on what device the data is stored. As data volumes grow and data services become more complex, iRODS is serving an increasingly important role in data management.

+[root@icommand .irods]# pwd
+/root/.irods
+[root@icommand .irods]# ls -la
+total 16
+drwx------. 2 root root 136 Sep 29 08:53 .
+dr-xr-x---. 6 root root 206 Sep 29 08:53 ..
+-rw-r--r--. 1 root root 253 Sep 29 08:14 irods_environment.json
+```
+
+How to start:
+
+step 1:
+```
+[root@icommand .irods]# iinit
+```
+
+step 2:
+
+copy the link (second one) which you got from terminal to the browser or just ctrl+left_mousebutton
+
+example:
+
+https://keycloak-dev.it4i.cz:8443/auth/realms/IT4i_AAI/protocol/openid-connect/auth?nonce=1cc259e35a0043fb871abb79185d6d838d2b99060baa5bf635515181df9c942b&state=701842d9867655918ca165f6d7635a155723afb4d37afff0cf550e77114bc519&redirect_uri=https://irods-api.it4i.cz:8443/authcallback&client_id=IT4I_IRODS_AUTH&&scope=openid&response_type=code&access_type=offline&prompt=login%20consent
+
+click to B2ACCESS atorization and continue autentication flow
+
+you have to see this output `Successfully authenticated user. The browser tab can be safely closed.` in browser
+current problem is: - after validating authorization token, it becomes passed and any new command, such as ils creates new authorization at keycloak.
