 Summary
 -------
 
-The `dwarf2` plugin is to be a replacement of `pri_dwarf` plugin. The workflow is to run 
-`dwarfdump -dil ${TARGET_PROG} | python -c "import sys;from pandare.extras import dwarfdump;dwarfdump.parse_dwarfdump(sys.stdin.read(), '${TARGET_PROG}')"`.
-This is going to generate 4 json DWARF symbol files including: Line Info, Global Variables, Function Info, and Type Info. Place these json files under debug path for this plugin to read.
+The `dwarf2` plugin is to be a replacement of `pri_dwarf` plugin.
+
+Before running the plugin, you need to extract DWARF debug information from the target binary into json files using the `pandare.extras.dwarfdump` module. You can do this by running the following commands:
+
+This plug-in/script is used for [LAVA](https://github.com/panda-re/lava), so it assumes that the binary has the following CFLAGS `-O0 -g -gdwarf-2 -fno-stack-protector`. 
+This is because these flags ensure all the input needed for Python to parse the dwarf dump is available to plant vulnerabilities.
+
+```bash
+# Assume TARGET_PROG is the path to the target program with DWARF debug info
+dwarfdump -dil ${TARGET_PROG} > tmp.dump
+python3 -m pandare.extras.dwarfdump tmp.dump temp
+
+# Alternatively, you can use the following one-liner to achieve the same result:
+dwarfdump -dil <binary> | python3 -m pandare.extras.dwarfdump <binary-prefix>
+```
+This is going to generate 4 JSON DWARF symbol files including: 
+* Line Info
+* Global Variables
+* Function Info
+* Type Info
+
+Place these JSON files under debug path for this plugin to read.
