+# Cicer
+
+Cicer is a web based software to manage the stock, purchases and balance of a consumer association. It has being created for the needs of the [Garbanzo Negro](http://garbanzonegro.org).
+
+## deploy it
+
+Build a copy using make:
+```
+$ make build
+```
+
+Create a secret for the authentication tokens:
+```
+$ head -c 21 < /dev/urandom | base64
+```
+
+Now you can copy the build folder and the cicer binary to your server and run it like:
+```
+$ ./cicer -assets 'path/to/build' -secret 'scret' -addr ':8000'
+```
+Instead of flags all the params can be passed as env variables see the names between `{` and `}` in:
+```
+$ ./cicer -h
+```
+
+## run for development
+
+To run it in develop mode build and run the backend:
+```
+$ go build
+$ ./cicer
+```
+
+And run the frontend with npm:
+```
+$ npm start
+```
+This will open a browser pointing to `http://localhost:3000` where you will see any changes you do in the javascript side (the backend side needs recompilation).
+
+## Initialize data
+
+When you run cicer it will print an authentication token that we can use to set up some initial data, see `setup.sh`:
+```
+$ ./setup.sh the.hexadecimal.token
+```
