 # sensorgnome-control
-Master control process for a sensorgnome field computer.
 
-This repo used to hold both control and [support](https://github.com/sensorgnome-org/sensorgnome-support) software, but was split into two repos.
+Main control process for a sensorgnome field computer.
+
+The main control process consists of a JavaScript node.js application found in the src
+directory. Npm is used to install all the dependencies: run `npm install`.
+
+The `gen-package.sh` script produces a debian package that includes the application, the
+systemd service file, and all the javascript dependencies (i.e., `npm install` is run as part
+of the packaging process). The reason to bundle the dependencies is so the deb can be carried to
+a station on a flash stick and used to upgrade without requiring an internet connection.
+
+History: this repo used to hold both control and
+[support](https://github.com/sensorgnome-org/sensorgnome-support)
+software, but was split into two repos.
+Also the term "master" has been replaced by "main".
