+NAME
+    RTIR-Extension-MISP - Integrate RTIR with MISP
+
+DESCRIPTION
+    MISP <https://www.misp-project.org/> is a platform for sharing threat
+    intelligence among security teams, and this extension provides
+    integration from "https://bestpractical.com/rtir" in RTIR.
+
+RTIR VERSION
+    Works with RTIR 5.0
+
+INSTALLATION
+    perl Makefile.PL
+    make
+    make install
+        May need root permissions
+
+    Edit your /opt/rt4/etc/RT_SiteConfig.pm
+        Add this line:
+
+            Plugin('RTIR::Extension::MISP');
+
+    Clear your mason cache
+            rm -rf /opt/rt4/var/mason_data/obj
+
+    Restart your webserver
+
+CONFIGURATION
+    Set the following in your RT_SiteConfig.pm with details for the MISP
+    instance you want RTIR to integrate with.
+
+        Set(%ExternalFeeds,
+            'MISP' => [
+                {   Name        => 'MISP',
+                    URI         => 'https://mymisp.example.com',  # Change to your MISP
+                    Description => 'My MISP Feed',
+                    DaysToFetch => 5,  # For the feed page, how many days back to fetch
+                },
+            ],
+        );
+
+DETAILS
+    This integration adds several different ways to work between the MISP
+    and RTIR systems as described below.
+
+  Consume Feed from MISP
+    After adding the MISP configuration described above, the Feeds page in
+    RTIR at RTIR > Tools > External Feeds will have a new MISP option
+    listed. This feed pulls in events for the past X number of days based on
+    the DaysToFetch configuration. From the feed display page, you can click
+    the "Create new ticket" button to create a ticket with information from
+    the MISP event.
+
+  MISP Portlet on Incident Display
+    On the Incident Display page, if the custom field MISP Event ID has a
+    value, a portlet MISP Event Details will be displayed, showing details
+    pulled in from the event via the MISP REST API.
+
+  Update MISP Event
+    On an incident with a MISP Event ID, the Actions menu will have an
+    option "Update MISP Event". If you select this action, RTIR will update
+    the existing MISP event with an RTIR object, including data from the
+    incident ticket.
+
+  Create MISP Event
+    If MISP Event ID has no value, the Actions menu on incidents shows an
+    option to "Create MISP Event". Select this to create an event in MISP
+    with details from the incident ticket.

+=head1 DETAILS
+
+This integration adds several different ways to work between the MISP and
+RTIR systems as described below.
+
+=head2 Consume Feed from MISP
+
+After adding the MISP configuration described above, the Feeds page in RTIR at
+RTIR > Tools > External Feeds will have a new MISP option listed. This feed
+pulls in events for the past X number of days based on the DaysToFetch
+configuration. From the feed display page, you can click the "Create new ticket"
+button to create a ticket with information from the MISP event.
+
+=head2 MISP Portlet on Incident Display
+
+On the Incident Display page, if the custom field MISP Event ID has a value,
+a portlet MISP Event Details will be displayed, showing details pulled in
+from the event via the MISP REST API.
+
+=head2 Update MISP Event
+
+On an incident with a MISP Event ID, the Actions menu will have an option
+"Update MISP Event". If you select this action, RTIR will update the existing
+MISP event with an RTIR object, including data from the incident ticket.
+
+=head2 Create MISP Event
+
+If MISP Event ID has no value, the Actions menu on incidents shows an option to
+"Create MISP Event". Select this to create an event in MISP with details from
+the incident ticket.

+Since you are using Microsoft Windows, you will need the 'nmake' utility
+before installation. It's available at:
+
+  http://download.microsoft.com/download/vc15/Patch/1.52/W95/EN-US/Nmake15.exe
+      or
+  ftp://ftp.microsoft.com/Softlib/MSLFILES/Nmake15.exe
+
+Please download the file manually, save it to a directory in %PATH% (e.g.
+C:\WINDOWS\COMMAND\), then launch the MS-DOS command line shell, "cd" to
+that directory, and run "Nmake15.exe" from there; that will create the
+'nmake.exe' file needed by this module.
+
+You may then resume the installation process described in README.
