+# tango.info plugin for MusicBrainz Picard
+Automatically get *genre, date and singers* from **tango.info**, right inside of MusicBrainz Picard.
+
+## Usage
+Then open Picard, navigate to `Options -> Options -> Plugins` and enable
+the one called `Tango.info Adapter`, then restart and use Picard
+like you usually would.
+
+If(and **only if**) there is a valid `barcode` tag for your files, the plugin
+will try to look up the corresponding album on *tango.info* and fill in the
+`genre`(capitalized), `vocal`(for Singers) and `date` tags for you.
+
+## How it works
+The plugin looks up the barcode of an album, constructs the url for the corresponding
+*tango.info* album('product'/'TINP') page, parses the HTML, looks for the
+`tracks` table and extracts `genre`, `Perf date` and `Vocalist(s)`.
+
+## What is a TINT
+See [tango.info wiki: TINT](https://tango.info/wiki/TINT)
+`<TINP>-<Side#>-<Track#>`, example: `TINT:00743216335725-1-5`.
+
+[tango.info wiki: TINP](https://tango.info/wiki/TINP) - *Tango Info Number
+for a Product* is a 14-digit numeric tango.info code used by tango.info and
+others.
+
+## Future
+Provided tango.info's [Tobias Conradi](https://tango.info/tangoinfo/eng/contact)
+does not change the page structure in a manner that breaks this plugin, you
+might be able to map instrumentalists and vocalists to the id3 tags of your
+liking, or download cover art. Just construct the respective regex and change a
+few lines.
