+WebSocket Remote Card (WSRC)
+============================
+
+WSRC (*Web Socket Remote Card*) is a mechanism by which card readers can be made remotely available
+via a computer network.  The transport mechanism is (as the name implies) a WebSocket.  This transport
+method was chosen to be as firewall/NAT friendly as possible.
+
+WSRC Network Architecture
+-------------------------
+
+In a WSRC network, there are three major elements:
+
+* The **WSRC Card Client** which exposes a locally attached smart card (usually via a Smart Card Reader)
+  to a remote *WSRC Server*
+* The **WSRC Server** manges incoming connections from both *WSRC Card Clients* as well as *WSRC User Clients*
+* The **WSRC User Client** is a user application, like for example pySim-shell, which is accessing a remote
+  card by connecting to the *WSRC Server* which relays the information to the selected *WSRC Card Client*
+
+WSRC Protocol
+-------------
+
+The WSRC protocl consits of JSON objects being sent over a websocket.  The websocket communication itself
+is based on HTTP and should usually operate via TLS for security reasons.
+
+The detailed protocol is currently still WIP. The plan is to document it here.

-        # ASN.1 OBJECT IDENTIFIER Decoding Issue:
-        #
-        # In ASN.1 BER/DER encoding, the first two arcs of an OBJECT IDENTIFIER are
-        # combined into a single value: (40 * arc0) + arc1. This is encoded as a base-128
-        # variable-length quantity (and commonly known as VLQ or base-128 encoding)
-        # as specified in ITU-T X.690 §8.19, it can span multiple bytes if
-        # the value is large.
-        #
-        # For arc0 = 0 or 1, arc1 must be in [0, 39]. For arc0 = 2, arc1 can be any non-negative integer.
-        # All subsequent arcs (arc2, arc3, ...) are each encoded as a separate base-128 VLQ.
-        #
-        # The decoding bug occurs when the decoder does not properly split the first
-        # subidentifier for arc0 = 2 and arc1 >= 40. Instead of decoding:
-        #   - arc0 = 2
-        #   - arc1 = (first_subidentifier - 80)
-        # it may incorrectly interpret the first_subidentifier as arc0 = (first_subidentifier // 40),
-        # arc1 = (first_subidentifier % 40), which is only valid for arc1 < 40.
-        #
-        # This patch handles it properly for all valid OBJECT IDENTIFIERs
-        # with large second arcs, by applying the ASN.1 rules:
-        #   - if first_subidentifier < 40: arc0 = 0, arc1 = first_subidentifier
-        #   - elif first_subidentifier < 80: arc0 = 1, arc1 = first_subidentifier - 40
-        #   - else: arc0 = 2, arc1 = first_subidentifier - 80
