+### Command to build the docker image:
+
+```docker
+docker build -t openfhe-docker .
+```
+Make sure you run this command from the same folder where the Dockerfile is located (in the "docker" folder of the openfhe-python repository).
+
+### Command to check if the image is built:
+
+```docker
+docker images
+```
+
+You should see a "openfhe-docker" in the list
+
+### Command to create the container from the image:
+
+```docker
+docker run -d -p 8888:8888 openfhe-docker
+```
+
+### Command to check if the container is running:
+
+```docker
+docker ps
+```
+
+You should see openfhe-docker running
+
+### This openfhe-docker has jupyterlab installed in it which has access to openfhe installation and is accessible via localhost. To run the jupyterlab use:
+
+```docker
+[http://localhost:8888](http://localhost:8888/)
+```
+
+All the code can be executed through this jupyterlab now
+
+## Alternate way to execute the code in this docker:
+
+### Go inside the docker, use:
+
+```docker
+docker exec -it <container-name> /bin/bash
+```
+
+replace the <container-name> with the name that you see when you use the command "docker run -d -p 8888:8888 openfhe-docker"
+
+This takes you to a terminal interface inside the container which has all the dependencies installed.
+
+You can now clone a github repo that depends on OpenFHE and run the code.
