+# Getting Started 
+This section is for deployment of ICON-Tezos bridge in the testnet. This file also documents all the dependencies and prerequisits that are necessary for the bridge. 
+
+## Setting up on ICON
+Install `goloop` cli for interacting with the ICON chain. 
+
+```
+    https://github.com/icon-project/goloop/blob/master/doc/build.md
+```
+
+## Setting up on Tezos 
+Install `octez-client`, cli tool in tezos for interacting with the Tezos chain.
+
+```
+https://opentezos.com/tezos-basics/cli-and-rpc/
+```
+Once the `octez-client` is all set, you will have to change the network that your `octez-client` is connected to.
+
+```sh
+octez-client --endpoint https://ghostnet.tezos.marigold.dev config update
+```
+
+## ICON Tezos Bridge Configuration(Testnet)
+For the complete deployment, build and running the relay navigate to 
+```sh
+$ cd $BASE_DIR/devnet/docker/icon-tezos/scripts
+$ bash testnet.i2t.bmr.sh
+```
+When running the script, first wallets are created and we wil have to fund the wallets using the faucet of the respective chains.
+
+For example you will get a message like this.
+```
+Fund the recently created wallet and run the script once again
+icon bmc wallet: hxbc77026b7c3823744d5746507ab5bdb570ef9ca3
+icon bts wallet: hx05256b36068144ec4523fd3943966ea018208ddb
+icon bmr wallet: hx416d86b01f48ffe425a8a8a5f61182b1c17a339d
+icon fa wallet : hxb7d5d680576de816459ad7b4af659886b2b0e4e3
+tz bmr wallet : tz1dxhHuEcZNXoFyX3PX5A8NNpWnJ3MKHDY2
+```
+Fund the icon wallets using the faucet
+```
+https://faucet.iconosphere.io/
+```
+Fund the tezos wallets using the faucet
+```
+https://faucet.marigold.dev/
+```
+
+Rerun the script again and wait for the relay to start. This script will deploy the ICON smart contracts, Tezos smart contracts and register the native coin of the destination chains in its own chain. 
+
+```sh
+$ bash testnet.i2t.bmr.sh
+```
