   <p>
-    Some text
+    The Bangladesh Core FHIR Implementation Guide defines national base
+    profiles, code systems, and value sets to ensure interoperability across
+    digital health systems under DGHS and MoHFW.
+  </p>
+
+  <h3>Motivation</h3>
+  <p>
+    Bangladesh has multiple health information systems developed over the
+    years, including DHIS2, multiple hospital automation systems, field automation systems, and HRIS. These systems use different data
+    standards, which makes interoperability difficult. This guide aligns
+    national systems with HL7® FHIR® R4 to ensure semantic consistency and
+    facilitate integration with global initiatives.
+  </p>
+
+  <h3>Scope</h3>
+  <ul>
+    <li>Patient identity management (UHID, NID, BRN)</li>
+    <li>Health facility and organization registry</li>
+    <li>Immunization, laboratory, and condition profiles</li>
+    <li>Terminology services (ICD-11, SNOMED subsets, local CodeSystems)</li>
+  </ul>
+
+  <h3>National Digital Health Architecture</h3>
+  <p>
+    The following diagram shows how FHIR-based services are integrated into
+    Bangladesh's national digital health architecture:
