-                To find these checksums, you can comment the statements out
+                Ideally, you should locate these checksums from the upstream
+                website and use them in your recipe.
+                However, many websites do not provide the checksums.
+                If such is the case, you can use a "build-fail" method that

+                To use the "build-fail" method, comment the statements out
                 and then attempt to build the software.
                 The build will produce an error for each missing checksum
                 and as part of the error message provide the correct checksum
