+----------
+Building the systray in linux will produce some `-Wdeprecated-declarations` warnings, like that:
+```
+cgo-gcc-prolog: In function ‘_cgo_3f9f61f961c9_Cfunc_gtk_font_button_get_font_name’:

 bitmask-systray assumes that you already have bitmaskd running.

+Standalone
+-------------
+
+Is also posible to compile the systray to be standalone (don't depend on bitmask):
+```
+  $ go build -tags standalone
+```
+It still requires a helper and openvpn installed to work. For linux the helper is
+[bitmask-root](https://0xacab.org/leap/bitmask-dev/blob/master/src/leap/bitmask/vpn/helpers/linux/bitmask-root)
+for windows and OSX there is [a helper written in go](https://0xacab.org/leap/riseup_vpn/tree/master/helper).
