+    all access to external update sites and their artifacts during installation and updates is tracked and reported so that you are made aware of the source of the content being installed and can decide whether to trust content from that source.
+    This provides an additional level of security in addition to the signing of artifacts.
+    Simply installing content, even without actually installing any associated artifacts, can in general reconfigure the installation and that could potentially be used for malicious purposes.
+    Also, simply because an artifact is signed, doesn't imply the artifact is necessarily trustworthy.
+    It is important to take into account the source of installed content before installing that content.
+    <p>
+    When installing new content as well as when installing updates,
+    the following <b>Trust Authorities</b> dialog is displayed showing the sites that have been contacted,
+    details about those sites,
+    and details about the specific content being installed from each site:
+    </p>
+    <p>
+    <img src="images/TrustAuthoritiesDialog.png" alt="Trust Authorities Dialog" style="max-width: 100%;"/>
+    </p>
+    <p>
+    All content must originate from sites explicitly accepted as trusted before installation proceeds and before library artifacts are downloaded.
+    The trusted authorities can be remembered in the preferences to avoid being prompted repeatedly for authorities that have already been considered as trusted.
+    Those recorded preferences are available for review and modification via the <b>Authorities</b> tab of the <b>Install/Update &rarr; Trust</b> preferences:

+    </p>
+    <p>
+    The system property <code>p2.trustedAuthorities</code> can be used to specify a (comma or space separated) list of authorities considered trusted.
+    The default value is effectively <code>-Dp2.trustedAuthorities=https://download.eclipse.org,https://archive.eclipse.org</code>,

+    In the event that a PGP key is compromised, the key may be revoked.
+    Artifacts signed before the revocation date are generally still valid, 
+    but an attacker can create back-dated signatures.
+    Therefore, any artifact signed with a revoked key, 
+    and any internal exception that occurs while processing the revocation information of the key,
+    will result in that artifact being treated as a suspicious artifact,
+    leading to a <b>Trust Artifacts</b> prompt:
