 ## Debug
 
-To keep the debug symbols in the resulting OpenTelemetry Collector binary, set the configuration property `debug_compilation` to true.
+### Debug symbols
+
+By default, the LDflags are set to -s -w, which strips debugging symbols to produce a smaller OpenTelemetry Collector binary. To retain debugging symbols and DWARF debugging data in the binary, override the LDflags as shown:
+
+```console 
+ocb --ldflags=" " --config=builder-config.yaml.
+```
+
+### Debugging with Delve
+
+To ensure the code being executed matches the written code exactly, debugging symbols must be preserved, and compiler inlining and optimizations disabled. You can achieve this in two ways:
+
+1. Set the configuration property `debug_compilation` to true.
+2. Manually override the ldflags and gcflags `ocb --ldflags=" " --gcflags="all=-N -l" --config=builder-config.yaml.`
 
 Then install `go-delve` and run OpenTelemetry Collector with `dlv` command as the following example:
