+
+![](images/full.png)
+
+![](images/short.png)
+
+# Requirements
+
+  - NetworkManager/`nmcli`
+  - `sh`
+  - `awk`
+    - tested on nawk, gawk, mawk, [goawk](https://github.com/benhoyt/goawk), Plan 9 awk and busybox awk.
+
+# Usage
+
+`nm-vpn` gets active connection info from `nmcli`, looks for interface type `tun`, `tap`, `vpn`. A VPN connection is treated as established only when `tun`|`tap` is present, when it's not and a `vpn` connection is listed as active it is treated as initializing.
+
+# Tunables
+
+`init_color` - color used for marking a connection in initializing state, default is '#FFFF00'
+
+`on_color` - color used for marking a connection in established state, default is '#00FF00'
+
+## Output
+
+When `tun`|`tap` is active, `nm-vpn` will print in the following form:
+  - Full: `VPN Name`
+  - Short: `ON`
+  - Color will be set to `on_color` value
+
+When `tun`|`tap` in not active, `nm-vpn` will print in the following form:
+  - Full: `VPN Name`
+  - Short: `INIT`
+  - Color will be set to `init_color` value
+
+# Config
