 # Funding Dev Accounts
 
-As Pop Network uses the Relay chain token as the native token, the dev accounts (alice, bob, etc) are not funded on Pop Network by default.
-Therefore, after network launch there needs to be a reserve transfer from the Relay chain to the dev accounts on Pop Network.
-This script performs these reserve transfers to fund the dev accounts from the Relay chain.

 ## Running the script
 
 1. Spin up a Polkadot Network locally with Pop Network running
-2. In the `main.rs` file change:
-- the `PARA_ID` to the paraId of Pop Network e.g. `9090`
-- change the `relay_api` port number to the port number of the Relay chain running on your machine
-- change the `pop_api` port number to the port number of Pop Network running on your machince
-3. Run the script

-```
+```shell

 ### Troubleshooting
 
-Pop Network is ongoing constant new updates and features to its runtime. It is common for the metadata to be out-dated.
