 Researching a way to bring java alike OSGi to nodejs for hot swappable modules.   
 This is not an intention to replace nodejs modules but a way to swap certain areas of the application such as bringing new versions without a restart
 
+Usage:
+-------
+Bundle:   
+A bundle should export bundleStart, or bundleActivator object   
+
+This specific bundle it will receive messages from core-shell bundle, execute a shell command and print output   
+Placing the bundle in {app path}/bundles/shell-test/index.js
+```javascript
+var log = require('hlogger').createLogger('shell-test');
+var child = require('child_process');
+
+function bundleStart(context) {
+
+	log.info("Command provider installed");
+
+	// Create a bash and transport commands
+	context.events
+		.channel('core-shell')
+		.after('cmd',(req,res,e) => {
+			if(e.count != 0) return;
+			e.wait();	
+			var shcmd = req.cmd + " " + req.args.join(" ");
+			var proc = child.exec(shcmd);
+			proc.stdout.pipe(res);
+			proc.stderr.pipe(process.stderr);
+			proc.on('close',function() {
+			e.done();
+		});			
+	});
+}
+module.exports.bundleStart = bundleStart;
+```
+
+Main app:   
+```javascript
+var BundleManager = require('node-hci');   // or path to node-hci since is not published in npm yet
+// This will load bundles from the {app path}/bundles
+var manager = new BundleManager({runPath: __dirname + "/bundles"});
+manager.loadDefaultBundles();
+```
+
+
