-##  Step-2: Update the Submodule, To to project area
+##  Step-2: Clone and update the Submodule
 ```bash
+   git clone https://github.com/dineshannayya/riscduino.git
+   cd riscduino
    git submodule init
    git submodule update
 ```
-## Step-3: clone Openlane scripts under workarea
+
+## Note-1: RTL to GDS Docker
+    - Required openlane and pdk are moved inside the riscduino docker to avoid the external dependency. 
+    - flow automatically pull the required docker based on MPW version.
+    - RTL to gds docker is hardcoded inside File: openlane/Makefile
 ```bash
-   git clone https://github.com/The-OpenROAD-Project/OpenLane.git
+     OPENLANE_TAG = mpw6
+     OPENLANE_IMAGE_NAME = riscduino/openlane:$(OPENLANE_TAG)
+```
+## Note-1.1: View the RTL to GDS Docker content
+    - for MPW-6 caravel pdk and openlane avaible inside riscduino/openlane:mpw6 docker 
+    - caravel, openlane and pdk envionment are automatically pointed to internal docker pointer
+    - To view the docker contents
+```bash
+    docker run -ti --rm riscduino/openlane:mpw6  bash
+    cd /opt/pdk_mpw6     -  pdk folder
+    cd /opt/caravel      -  caravel folder 
+    cd /openlane         -  openlane folder

+    - for MPW-6 caravel and pdk avaible inside riscduino/dv_setup:mpw6 docker this is used for RTL to gds flows
+    - caravel and pdk envionment are automatically pointed to internal docker pointer

-```bash
-   source ~/.bashrc
-   cd OpenLane
