+## About
+
+*Thekno* is a [Progressive Web App](https://en.wikipedia.org/wiki/Progressive_web_applications) and a reference implementation for a set of APIs formalized as part of this project.
+
+By implementing these APIs any community radio will be able to offer a Web App for their listeners who will be able to install it similar to a native app. *Thekno* offers a variety of configuration options for providers including live streams, social platforms, content suggestions and more.
+
+## Design Goals
+
+* **Familiarity**
+
+  *Thekno* should feel and behave like other apps that people use on their phones and desktops.
+* **Explorable**
+
+  *Thekno* should encourage users to explore the diversity of your community radio. Both new content and content that matches the user’s interest should be easy to find.
+
+* **Privacy**
+
+  *Thekno* aims for client-storage only and embraces the data sovereignty of its users. Personal information should only be stored on the users device.

+      The `width` and `height` parameters are optional and positive integers.
+      If both parameters have been provided the image should be cropped so it fits the specified dimensions.
+      The algorithm that defines the cutout for the image is left to the backend implementation.
+      If the only one parameter is given the image should be scaled to fit the specified width or height
+      while maintaining its aspect ratio. If neither `width` nor `height` have been given that backend
+      SHOULD return the image in its original size preferably not smaller than 1000px.
+
+
+      The `format` query parameter may be `PNG`, `JPEG` or `WEBP`. The backend SHOULD treat the format
+      as preferred by the client but MAY return any other content type. In case `format` has not been
+      provided the image MUST be returned in format the backend finds suitable.
+
+
+      The server SHOULD serve images with an `Access-Control-Allow-Origin` header that allows the client
+      to interact with the resource once it’s loaded.

docs/apis/content/concepts.md

+The API is based on three pillars namely series’, broadcasts, and recordings.
+
+A short nomenclature: 
+
+Series
+: A radio program or show that is usually scheduled to be aired on a regular interval. 
+
+Broadcast
+: An instance of a series or in less technical terms the time and date when a series has been aired.
+
+Recording:
+: A segment, report, or story that encapsulates the actual audio data.
+
+Every series has multiple broadcasts and every broadcast usually has multiple recordings. It may also happen that a recording was aired more than once so that it appears in multiple broadcasts. Vice versa you may find recordings that are not associated to any broadcast. In that case the Recording was never aired and was only submitted for archival purposes.
+

+The Thekno Content API is a REST-like web API that allows a client to implement a 
+media library. It is focused on the needs of community radios. Every application
+that implements the Thekno Content API will be able to use the Thekno Progressive Web App. 
+
+If you plan on implementing the API for your community radio you may use this
+document as a reference. For a reference implementation you can look at the
+[lohrothek-api project](https://git.hack-hro.de/lohro/lohrothek/lohrothek-api).
+In case you already use the lohrothek-api project or any other project that
+provides this API there is probably no good reason to look at this document 🙂.
+
+Most of the low-level concepts like query parameters, request methods, response codes,
+etc. are defined in the [HTTP specification](https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol) and are not part of this document. If you’re
+unfamiliar with these words or struggle with some of the more basic concepts
+of this documentation you may want to read an introduction to the HTTP
+protocol in general and REST APIs in particular first. A good starting point are
+the respective Wikipedia articles and [restfulapi.net](https://restfulapi.net/).
+
+The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", 
+"SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to 
+be interpreted as described in [RFC 2119](https://tools.ietf.org/html/rfc2119).

+
+
+        It must also set the `Access-Control-Allow-Origin` header to the hostname the
+        client is served under or `*` to allow any client. The server SHOULD support
+        the `Range` header to allow clients to request only a part of the content.
