+# Introduction
+
+This section provides basic information on how to gain access to IT4Innovations Information systems and project membership.
+
+## Account Types
+
+There are two types of accounts on IT4Innovations:
+
+* [**e-INFRA CZ Account**][1]
+    Intended for all persons affiliated with an academic institution from the Czech Republic ([eduID.cz][a]).
+
+* [**IT4I Account**][2]
+    Intended for all persons who are not eligible for e-INFRA CZ account.
+
+Once you create an account, you can use it only for communication with IT4I support and accessing the SCS information system.
+If you want to access IT4I clusters, your account must also be **assigned to a project**.
+
+For more information, see the section:
+
+* [**Get Project Membership**][3]
+    if you want to become a collaborator on a project, or
+
+* [**Get Project**][4]
+    if you want to become a project owner.

+# e-INFRA CZ Account
+
+[e-INFRA CZ][1] is a unique research and development e-infrastructure in the Czech Republic,
+which provides capacities and resources for the transmission, storage and processing of scientific and research data.
+IT4Innovations has become a member of e-INFRA CZ on January 2022.
+
+!!! important
+    Only persons affiliated with an academic institution from the Czech Republic ([eduID.cz][6]) are eligible for an e-INFRA CZ account.
+
+## Request e-INFRA CZ Account
+
+1. Go to [https://signup.e-infra.cz/fed/registrar/?vo=IT4Innovations][2]
+1. Select a member academic institution you are affiliated with.
+1. Fill out the e-INFRA CZ Account information (username, password and ssh key(s)).
+
+Your account should be created in a few minutes after submitting the request.
+
+Once your e-INFRA CZ account is created, it is propagated into IT4I systems
+and can be used to access [SCS portal][3] and [Request Tracker][4].
+
+Continue with requesting a project or project membership.
+
+## Logging Into IT4I Services
+
+The table below shows how different IT4I services are accessed:
+
+| Services | Access  |
+| -------- | ------- |
+| Clusters | SSH key |
+| IS, RT, web, VPN | e-INFRA CZ login |
+| Profile<br>Change&nbsp;password<br>Change&nbsp;SSH&nbsp;key | Academic institution's credentials<br>e-INFRA CZ / eduID |
+
+You can change you profile settings at any time.

+# Get Project Membership
+
+!!! note
+    You need to be named as a collaborator by a Primary Investigator (PI) in order to access and use the clusters.
+
+## Authorization by Web
+
+This is a preferred method if you have an IT4I or e-INFRA CZ account.
+
+Log in to the [IT4I SCS portal][e] and go to the **Authorization Requests** section. Here you can submit your requests for becoming a project member. You will have to wait until the project PI authorizes your request.
+
+## Authorization by Email
+
+An alternative way to become a project member is on request sent via [email by the project PI][8].

-# SSH Key Management
+# SSH

-When you first create an account with IT4Innovations, you receive an SSH key with your credentials. However, you can manage your own SSH key for authentication to clusters.
+Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network.
+SSH uses public-private key pair for authentication, allowing users to log in without having to specify a password. The public key is placed on all computers that must allow access to the owner of the matching private key (the private key must be kept **secret**).

-## Managing Your Own Key
+## Private Key

-1. Generate your SSH key (see the [OpenSSH Keys (UNIX)][1] or [PuTTY (Windows)][2] section).
+!!! note
+    The path to a private key is usually /home/username/.ssh/

-1. Go to [https://extranet.it4i.cz/ssp/index.php?action=changesshkey][a]
+A private key file in the `id_rsa` or `*.ppk` format is present locally on local side and used for example in the Pageant SSH agent (for Windows users). The private key should always be kept in a safe place.

-1. Enter your username, password and public SSH key.
+An example of private key format:

-1. Changes will take effect immediately.

+The computational resources of IT4I are allocated by the Allocation Committee via several [allocation mechanisms][a] to a project investigated by a Primary Investigator. By allocating the computational resources, the Allocation Committee is authorizing the PI to access and use the clusters.

 * Academic researchers may apply via Open Access Competitions.
 * Commercial and non-commercial institutions may also apply via the Directors Discretion.
@@ -8,11 +12,63 @@ Computational resources may be allocated via several [allocation mechanisms][a]:

 In all cases, IT4Innovations’ access mechanisms are aimed at distributing computational resources while taking into account the development and application of supercomputing methods and their benefits and usefulness for society. The applicants are expected to submit a proposal. In the proposal, the applicants **apply for a particular amount of core-hours** of computational resources. The requested core-hours should be substantiated by scientific excellence of the proposal, its computational maturity and expected impacts. The allocation decision is based on the scientific, technical, and economic evaluation of the proposal.

-For more information, see [Computing resources allocation][a] and [Obtaining Login Credentials][1].
+## Becoming Primary Investigator
+
+Once you create an account, log in to the [IT4I Information System][e] and apply for a project.
+You will be informed by IT4I about the Allocation Committee decision.
+Once approved by the Allocation Committee, you become the Primary Investigator (PI) for the project
+and are authorized to use the clusters and any allocated resources as well as authorize collaborators for your project.
+
+## Authorize Collaborators for Your Project
+
+As a PI, you can approve or deny users' requests to join your project. There are two methods of authorizing collaborators:
+
+### Authorization by Web
+
+This is a preferred method if you have an IT4I or e-INFRA CZ account.
+
+Log in to the [IT4I SCS portal][e] using your credentials and go to the **Authorization Requests** section.
+Here you can authorize collaborators for your project.
+
+### Authorization by Email (An Alternative Approach)
+
+In order to authorize a Collaborator to utilize the allocated resources, the PI should contact the [IT4I support][f] (email: [support\[at\]it4i.cz][g]) and provide the following information:
+
+1. Identify their project by project ID.
+1. Provide a list of people, including themself, who are authorized to use the resources allocated to the project. The list must include the full name, email and affiliation. If collaborators' login access already exists in the IT4I systems, provide their usernames as well.
+1. Include "Authorization to IT4Innovations" into the subject line.
+
+!!! warning
+    Should the above information be provided by email, the email **must be** digitally signed. Read more on [digital signatures][2] below.
+
+Example (except the subject line which must be in English, you may use Czech or Slovak language for communication with us):
+
+```console
+Subject: Authorization to IT4Innovations
+
+Dear support,
+
+Please include my collaborators to project OPEN-0-0.
+
+John Smith, john.smith@myemail.com, Department of Chemistry, MIT, US
+Jonas Johansson, jjohansson@otheremail.se, Department of Physics, RIT, Sweden
+Luisa Fibonacci, lf@emailitalia.it, Department of Mathematics, National Research Council, Italy
+
+Thank you,
+PI
+(Digitally signed)
+```
+
+!!! note
+    Web-based email interfaces cannot be used for secure communication; external application, such as Thunderbird or Outlook must be used. This way, your new credentials will be visible only in applications that have access to your certificate.

 ## Certificates for Digital Signatures

 We accept personal certificates issued by any widely respected certification authority (CA). This includes certificates by CAs organized in [International Grid Trust Federation][f], its European branch [EUGridPMA][g] and its member organizations, e.g. the [CESNET certification authority][h]. The Czech _"Qualified certificate" (Kvalifikovaný certifikát)_ provided by [PostSignum][i] or [I.CA][j], which is used in electronic contact with Czech authorities, is accepted as well.

-## End of User Account Lifecycle
-
-A user account that is not attached to an active project is deleted 1 year after the last project expires to which it was attached.
