+## PProfiling Usage Guide
+
+### Environment Variables
+
+- `PPROF`: Enable or disable profiling. Set to 1 to enable.
+- `MEM_PROFILE_DIR`: Directory to write memory profiles to.
+- `CPU_PROFILE_DIR`: Directory to write CPU profiles to.
+- `PPROF_TIME`: Polling time for CPU and memory profiles (with unit ex: 10s).
+- `MEM_PROFILE_RATE`: Memory profiling rate (default 4096).
+
+
+## How to Use
+
+1. Set the environment variables as per your requirements.
+
+```bash
+export PPROF=1
+export MEM_PROFILE_DIR=/path/to/memprofile
+export CPU_PROFILE_DIR=/path/to/cpuprofile
+export PPROF_TIME=10s
+export MEM_PROFILE_RATE=4096
+```
+
+2. Run your Go application. The profiler will start automatically if PPROF is set to 1.
+
+**Output**
+
+- Memory profiles will be written to the directory specified by MEM_PROFILE_DIR.
+- CPU profiles will be written to the directory specified by CPU_PROFILE_DIR.
+- Profiles will be written at intervals specified by PPROF_TIME.
+- Memory profiling rate is controlled by MEM_PROFILE_RATE.
+
+### Example
+
+```bash
+[+] GOOS: linux
+[+] GOARCH: amd64
+[+] Command: /path/to/your/app
+Available PPROF Config Options:
+MEM_PROFILE_DIR   - directory to write memory profiles to
+CPU_PROFILE_DIR   - directory to write cpu profiles to
+PPROF_TIME        - polling time for cpu and memory profiles (with unit ex: 10s)
+MEM_PROFILE_RATE  - memory profiling rate (default 4096)
+profile: memory profiling enabled (rate 4096), /path/to/memprofile
+profile: ticker enabled (rate 10s)
+profile: cpu profiling enabled (ticker 10s)
+```
+
+### Note
+
+- The polling time (PPROF_TIME) should be set according to your application's performance and profiling needs.
+- The memory profiling rate (MEM_PROFILE_RATE) controls the granularity of the memory profiling. Higher values provide more detail but consume more resources.
