-## 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

-```bash
- source ~/.bashrc
