 First, install [Docker](https://docs.docker.com/get-docker/) and

-Please follow the steps given below to run peaq-network-node parachian on your local machine connected with polkadot
-relaychain running in the PEAQ development environment. It is assumed that you have already downloaded the source code
-for peaq-network-node from the git repository
+Please use following command to run peaq-network-node parachian in the docker container connected with polkadot relaychain running in the PEAQ development environment. 
 
-1. CD into the peaq-network-node directory:
-```bash
-cd peaq-network-node
-```
-
-2. Checkout the appropriate branch:
-```bash
-git checkout run_peaq_dev_parachain_with_docker_commands
-```
-3. Create the following folder:
- ```bash
- mkdir ./.local
- ```
-
- The folder .local is needed because that is where data such as session keys are stored for validators. Also we bind mount from the container folder /root/.local to the host machine project root folder ./.local.
-
-Now run the following script to start a peaq-network-node parachain that will connect to the polkadot relay chain running in peaq development envoirnment:
  ```bash
-./scripts/docker_run.sh 
-./target/release/peaq-node \
---chain ./node/src/chain-specs/peaq-dev-parachain-raw.json \

 --chain ./node/src/chain-specs/rococo-local-relaychain-raw.json \

-```
-This command will first compile your code (if it is not already compiled), and then start a peaq-network-node parachain. The node running on your local machine will take sometime to sync up. Make sure that the parachain blocks are generated.  
-
-You can also replace the default command by appending your own. A few useful ones are as follows:
+ ```
 
-```bash
-# Purge the local dev chain
-./scripts/docker_run.sh ./target/release/peaq-node purge-chain --dev
-```
-```bash
-# Check whether the code is compilable
-./scripts/docker_run.sh cargo check
-```
+Once you run this command, wait for a few second. Now the peaq parachian should be running in the docker container that is connected to relaychain running in PEAQ dev environament.
