 How to manage the credentials store
 ===================================
 
-.. todo::
-   This page is a work in progress. For now, please refer to the `existing documentation
-   <https://intranet.softwareheritage.org/wiki/Credential_storage>`_.
+.. admonition:: Intended audience
+   :class: important
 
+   Staff members
+
+We use `pass <https://www.passwordstore.org/>`_, lightweight directory-based password
+manager, as our password manager.
+
+Repository
+----------
+
+https://forge.softwareheritage.org/source/credentials/
+
+Configuration
+^^^^^^^^^^^^^
+
+A ``git diff`` driver is available: it will allow you to run diff/show
+commands on encrypted files transparently. Its configuration is stored
+in the ``.gitconfig`` and ``.gitattributes`` file in the repo. To enable
+it you should configure your local copy to read ``.gitconfig`` from the
+repository, as it is not done by default for security reasons.
+
+The following will both clone your repo and set it up to use the diff
+driver:
+
+::
+
+   git clone ssh://git@forge.softwareheritage.org/diffusion/PWD/credentials.git
+   git config --local include.path ../.gitconfig
+
+(yes, it's really ``../``, because the path is relative to the ``.git/``
+directory)
+
+Information
+^^^^^^^^^^^

+More information can be found at `the repository <https://forge.softwareheritage.org/source/credentials/browse/master/README>`_.
