+# Overview
+
+The `pldmtool` for `GetPDR` command lacks to display all PDRs at once. It fetches only
+one PDR at a time. With a lot of sensors/effecters & with a lot of Host FRU pdrs
+coming in due to concurrent maintenance of the system,where the fru's are added/
+removed at runtime, it's really necessary to have a full system view.
+
+`pldm_visualise_pdrs.py` is a python script that can be used to fetch the PDR's
+from the BMC and can parse them to display a full view of available PDR's on system
+at any given point in time.
+
+# Requirements
+- Python 3.6+
+- graphviz
+    - Graphviz is open source graph visualization software. Graph visualization is
+      a way of representing structural information as diagrams of abstract graphs
+      and networks.
+    - There are standard package availabe for graphviz for both rpm based as well
+      as the debian based sytems, it can be installed using :
+
+```bash
+   RPM Distro : sudo dnf install graphviz
+   Debian Distro : sudo apt install graphviz
+   Mac Distro : brew install graphviz
+```
+- The `requirements.txt` file should list all Python libraries that the tool depend
+on, and that can be installed using:
+
+```bash
+    sudo pip3 install -r requirements.txt
+              (or)
+    pip3 install -r requirements.txt --user
+```
+# Usage
+
+```ascii
+usage: pldm_visualise_pdrs.py [-h] --bmc BMC --user USER --password PASSWORD [--port PORT]
+
+optional arguments:
+  -h, --help           show this help message and exit
+  --bmc BMC            BMC IPAddress/BMC Hostname
+  --user USER          BMC username
+  --password PASSWORD  BMC Password
+  --port PORT          BMC SSH port
+
+```
