+## Coverage
+
+Code coverage scripts generate a report that details how much of the Matter SDK
+source code has been executed, it also gives information on how often the Matter
+SDK executes segments of code and produces a copy of the source file, annotated
+with execution frequencies.
+
+```
+./scripts/build_coverage.sh
+```
+
+By default, Code coverage is performed at the unit testing level. Unit tests are
+created by developers, thus giving them the best vantage from which to decide
+what tests to include in unit testing. But you can extend the coverage test by
+scope and ways of execution with the following parameters:
+
+```
+  -c, --code                Specify which scope to collect coverage data.
+                            'core': collect coverage data from core stack in Matter SDK. --default
+                            'clusters': collect coverage data from clusters implementation in Matter SDK.
+                            'all': collect coverage data from Matter SDK.
+  -t, --tests               Specify which tools to run the coverage check.
+                            'unit': Run unit test to drive the coverage check. --default
+                            'yaml': Run yaml test to drive the coverage check.
+                            'all': Run unit & yaml test to drive the coverage check.
+```
+
+Also see the up-to-date unit testing coverage report of the Matter SDK
+(collected daily) at:

 ## Maintaining Matter
 
 If you make any change to the GN build system, the next build will regenerate
