+# vrr-infoscreen - Infoscreen for Public Transit Departures
+
+[vrr-infoscreen homepage](https://finalrewind.org/projects/vrr-fakedisplay/)
+
+vrr-infoscreen (formerly vrr-fakedisplay) shows departures at a public transit
+stop, serving both as infoscreen / webapp and LED departure monitor look-alike.
+
+It supports most german local transit networks and also some austrian ones.
+
+There's a public [vrr-infoscreen service on
+finalrewind.org](https://vrrf.finalrewind.org/). You can also host your own
+instance, see the Setup notes below.
+
+## Dependencies
+
+ * perl ≥ 5.10
+ * Cache::File (part of the Cache module)
+ * DateTime
+ * DateTime::Format::Strptime
+ * File::ShareDir
+ * GD
+ * Mojolicious
+ * Travel::Status::DE::EFA ≥ 1.15
+ * Travel::Status::DE::HAFAS ≥ 2.03
+ * Travel::Status::DE::URA ≥ 2.01
+
+## Setup
+
+First, build App::VRR::Fakedisplay which is required for the LED frontend:
+
+* perl Build.PL
+* ./Build
+* ./Build manifest
+* sudo ./Build install
+
+vrr-infoscreen is configured via environment variables:
+
+| Variable | Default | Description |
+| :------- | :------ | :---------- |
+| VRRFAKEDISPLAY\_LISTEN | `http://127.0.0.1:8091` | IP and Port for web service |
+| VRRFAKEDISPLAY\_STATS | _None_ | File in which the total count of (non-cached) backend API requests is written |
+| VRRFAKEDISPLAY\_CACHE | `/tmp/vrr-fakedisplay` | Cache directory |
+| VRRFAKEDISPLAY\_WORKERS | 2 | Number of concurrent worker processes |
+
+Set these as needed, create `templates/imprint.html.ep` (imprint) and
+`templates/privacy.html.ep` (privacy policy), and configure your web server to
+pass requests for vrr-infoscreen to the appropriate port.
+
+You can run the app using a Mojo::Server of your choice, e.g.  **perl
+index.pl daemon -m production** (quick&dirty, does not respect all variables)
+or **hypnotad** (recommended). A systemd unit example is provided in
+`examples/vrr-infoscreen.service`.
