-## 5. Contributing
+## 5. Deploying Fabric Driver for Weaver
+### 5.1 Setup
+
+Create a `.env` file using `.env.template` as the base and setting suitable environment variable values (see [here](#512-environment-variables)) and `config.json` files need to be checked and updated to match the network and relay that it will be connecting to.
+The .env contains information related to the network and relay. The config.json contains information about the ca admin, user and its org, that is used when connecting to the network.
+
+#### 5.1.1 Enabling TLS
+
+If the relay is TLS-enabled, set the following values in the `.env`:
+```
+RELAY_TLS=true
+RELAY_TLSCA_CERT_PATH=path_to_tls_ca_cert_pem_for_relay
+```
+- `path_to_tls_ca_cert_pem_for_relay` should be set to CA certificate file path
+
+To enforce secure communication over TLS with your driver, set the following values in the `.env`:
+```
+DRIVER_TLS=true
+DRIVER_TLS_CERT_PATH=path_to_tls_cert_pem_for_driver
+DRIVER_TLS_KEY_PATH=path_to_tls_key_pem_for_driver
+```
+- `path_to_tls_cert_pem_for_driver` should be set to driver's TLS certificate file path
+- `path_to_tls_key_pem_for_driver` should be set to driver's TLS private key file path
+
+#### 5.1.2 Environment variables
+
+The connection profile is required to set up the required material to communicate with the network. This should be supplied with the `CONNECTION_PROFILE` environment variable (ex: CONNECTION_PROFILE=path/to/con_profile.json)
+
+`<Hostname>:<Port>` for connecting relay: `RELAY_ENDPOINT` (ex: RELAY_ENDPOINT=localhost:9081 )
+
+Boolean for when to use mocked fabric communication: `MOCK` (ex: MOCK=true)
+
+`<Hostname>:<Port>` for the driver to be run on: `DRIVER_ENDPOINT` (ex: DRIVER_ENDPOINT=localhost:9093) (Not required for docker)
+
+Can pass in a variable 'local' for working with fabric and docker: `local` (ex: local=false)
+
+Can pass in a config file for the driver to be run with: `DRIVER_CONFIG` (ex: DRIVER_CONFIG=./config.json)
+
+`INTEROP_CHAINCODE` stores the name of the interop chaincode installed.
+
+`DB_PATH` stores the path hosting the database files containing the event subscription information.
+
+`WALLET_PATH` stores the path hosting the user wallets to access a network.
+
+NOTE: When specifying ensure that they match the config that the relay is using.
+
+### 5.2 Running
+Running the server: `yarn start-fabric-weaver-driver`
+
+Note: Can also be run in mocked mode by setting environment variable `MOCK=true`
