 # Introduction
 
+This section provides basic information on accounts required for access to IT4I services.
+These are the accounts used for communication with IT4I support and accessing the SCS information system.
+
+Creating an account does not automatically grant you access to IT4I clusters and computational resources.
+However, with this account, you can apply for computational resources and manage your project and project members (project owner)
+or request a project membership (project collaborator).
+
+!!! important
+    Be sure to request project or project membership once your account is created.
+    Accounts that are not assigned to a project will be deactivated.
+
+## Account Types
+
+There are two types of accounts on IT4I:
+
+* [**e-INFRA CZ Account**][1]
+    Intended for all persons affiliated with an academic institution from the Czech Republic (eduID.cz[a]).
+
+* **IT4I Account**
+    Intended for all persons who are not eligible for e-INFRA CZ account.
