+# Prerequisites for using Snowy
+
+To be allowed to [log in to Snowy](../getting_started/login_snowy.md),
+one needs all of these:
+
+- [An active research project](#an-active-research-project)
+- [An UPPMAX account](#an-uppmax-user-account)
+- [An UPPMAX password](#an-uppmax-password)
+
+These prerequisites are discussed in detail below.
+
+## An active research project
+
+One [prerequisite for using Snowy](#prerequisites-for-using-snowy)
+is that you need to be a member of an active SNIC
+or SIMPLER research project (these can have many names such as `uppmax[number]`,
+`snic[number]` or`naiss[number]`),
+where `[number]` represent a number, for example `uppmax2021-2-1`, `snic2022-6-230` or `naiss2023-6-382`).
+
+???- question "Forgot your Snowy projects?"
+
+    How to see you [research projects](project.md) is described at [research projects](project.md).
+
+    Spoiler: go to [https://supr.naiss.se](https://supr.naiss.se)
+
+[SUPR](https://supr.naiss.se/) (the 'Swedish User and Project Repository')
+is the website that allows one to request access to Snowy
+and to get an overview of the requested resources.
+
+???- question "How does the SUPR website look like?"
+
+    ![First SUPR page](./img/supr_first_page.png)
+
+    > First SUPR page
+
+    ![SUPR 2FA login](./img/supr_2fa.png)
+
+    > SUPR 2FA login. Use the SUPR 2FA (i.e. **not** UPPMAX)
+
+After logging in, the [SUPR](https://supr.naiss.se/)
+website will show all projects you are a member of,
+under the 'Projects' tab.
+
+???- question "How does the 'Projects' tab of the SUPR website look like?"
+
+    ![Example overview of SUPR projects](./img/supr_projects.png)
+
+    > Example overview of SUPR projects
+
+To see if a project has access to Snowy, click on the
+project and scroll to the 'Resources' section. In the 'Compute' subsection,
+there is a table. Under 'Resource' it should state 'Snowy @ UPPMAX'.
+
+???- question "How does the 'Resources' page of an example project look like?"
+
+    ![The 'Resources' page of an example project](./img/supr_project_naiss2024-22-49_resources.png)
+
+    > The 'Resources' page of an example project. This project has two compute
+    > resources and two storage resources. 
+    > A Snowy project would show the word 'Snowy' somewhere,
+    > so this is not a Snowy project.
+
+Note that the 'Accounts' tab can be useful to verify your username.
+
+???- question "How does the 'Accounts' tab help me find my username?"
+
+    ![An example of a SUPR 'Accounts' tab](./img/supr_accounts.png)
+
+    > An example of a SUPR 'Accounts' tab.
+    > The example user has username `richel-sens2023598`,
+    > which means his/her UPPMAX username is `richel`
+
+You can become a member of an active SNIC SENS by:
+
+- request membership to an existing project in SUPR
+- create a project. See the UPPMAX page on
+  how to submit a project application [here](project_apply.md)
+
+## An UPPMAX user account
+
+Another [prerequisite for using Snowy](#prerequisites-for-using-snowy)
+is that you must have a personal [UPPMAX user account](../getting_started/user_account.md).
+
+## An UPPMAX password
+
+Another [prerequisite for using Snowy](#prerequisites-for-using-snowy)
+is that you need to know your UPPMAX password.
+If you change it, it may take up to an hour before changes are reflected in Snowy.
+
+For advice on handling sensitive personal data correctly on Snowy, see our FAQ page.
