 The `dependencies` section within the app manifest gives Umbrel a list of app IDs that must be already installed in order for the user to install BTC RPC Explorer and also function.
 
-The `exports.sh` shell script is a simple script to export environmental variables that your `docker-compose.yml` can read. These env. vars. are also accessible when other apps start through their `docker-compose.yml` files.
+The `exports.sh` shell script is a simple script to export environmental variables that your `docker-compose.yml` can read. These env. vars. are also accessible when other apps start through their `docker-compose.yml` files. Most applications will not require this feature.
 
+If we (for example) wanted to share BTC RPC Explorer's Address API with other apps; that would look like this:
 ```sh
-export APP_BTC_RPC_EXPLORER_IP="10.21.21.12"
-export APP_BTC_RPC_EXPLORER_PORT="3002"
+export APP_BTC_RPC_EXPLORER_ADDRESS_API="electrumx"
 ```
 
 4\. For our app, we'll update `<docker-image>` with `getumbrel/btc-rpc-explorer`, `<tag>` with `v2.0.2`, and `<port>` with `3002`. Since BTC RPC Explorer doesn't need to store any persistent data and doesn't require access to Bitcoin Core's or LND's data directories, we can remove the entire `volumes` block.
