+# Modules
+Modules are loaded before services are started. This allows code to hook into services and register classes, event handlers, etc that alter the behaviors of services.
+
+## Example - Syncing BCH
+Let's say we have a node_module, named `bitcore-node-bch` with the following code
+
+```
+// index.js
+
+module.exports = class BitcoinCashModule {
+  constructor(services) {
+    services.Libs.register('BCH', 'bitcore-lib-cash', 'bitcore-p2p-cash');
+    services.P2P.register('BCH', services.P2P.get('BTC'));
+  }
+}
+```
+
+The module has the following dependencies
+```
+// package.json
+
+  "dependencies": {
+    "bitcore-lib-cash": "^8.3.4",
+    "bitcore-p2p-cash": "^8.3.4"
+  }
+
+```
+
+We could add this module by adding `bitcore-node-bch` to the modules array in bitcore.config.json
+
+```
+    modules: ['./bitcoin', 'bitcore-node-bch'],
+```
