+We will first describe some simple JSON values. We will use them later in more complicated
+objects with the Syntax `"filedName" : <name>`. We will write standard JSON types in the same
+way. (For example `<Number>` for a correct JSON number). If there are multiple allowed values we will
+write it with a `|`, for example `"fieldName" : <Number>|<String>` if `"filedName"` may contain a
+`<Number>` or a `<String>`.

+For optional fields we write the corresponding value as `<Maybe name>`. Optional fields

+#### Tick
+A Tick is an Object of the following form:
+```
+{
+"TickType" : <TickType>
+"TickValue" : <Number>
+}
+```
+The TickValue field is only requiered if the "TickType" field contains the Value "Tick"
+
+### Player
+#### UUID
+we encode UUID as Strings of the following form:
+"xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+Where every x represents a character between 0 and f.
+
+#### Player
+A Player is either an UnknownPlayer or a KnownPlayer. Aka `<Player>`
+is a synonym for `<KnownPlayer> | <UnknownPlayer>`. As a client you
+will never generate UUIDs for Player. This is always the job of the Server.
+
+##### KnownPlayer
+```
+{
+"PlayerUUID" : <UUID>
+"PlayerName" : <Maybe String>
+}
+```
+
+If `"PlayerName"` is set, the Player has a new Name. The Server will always use KnownPlayer. If
+you don't know that Player you should add it.
+
+##### UnknownPlayer
+```
+{
+"PlayerUUID" : <Maybe null>
+"PlayerName" : <String>
+}
+```
+Remark: `<Maybe null>` allows you to optionaly include this field with a `null` value. But
+you might omit it.
+
+UnknownPlayer are used to introduce new Player to the Server.
+
+### TickLeiste
+As every Session has exactly one TickLeiste attached to it, we never need to communicate an ID
+for a TickLeiste. But we still have to versions of TickLeiste.
+
+#### KnownTickLieste
+
+```
+[(<Tick>,[<KnownPlayer>])]
+```
+These are mainly used to communicate existing TickLeisten from the server to the client
+
+#### UnknownTickLeiste
+```
+[(<Tick>,[<UnknownPlayer>])]
+```
+These are mainly used so the client can initialize a TickLeiste.
+
+## Requests
+a client is allowed to make the following Requests
+
+### RequestType
+Every Request has a field `"RequestType" : <RequestType>`. For
+the allowed values of `<RequestType>` and the implication for the rest of
+the corresponding fields, look at the documentation of the specific requests.
+
+### SetPlayerTickR
+This request is used to set a player to a specific Tick. If the Player is an
+`UnknownPlayer` it will be added.
+```
+{
+"RequestType" : "SetPlayerTickR",
+"Player" : <Player>
+"Tick" : <Tick>
+}
+```
+
+### InitializeTickLeisteR
+
+Initialize a new TickLeiste, either one saved on the client side,
+to get a new empty one just set `"TickLeiste": []`
+
+```
+{
+"RequestType" : "InitializeTickLeisteR",
+"TickLeiste" : <UnknownTickLeiste>
+}
+```
+
+### TickLeisteR
+Request the current TickLeiste
+```
+{
+"RequestType" : "TickLeisteR",
+}
+```
+This is used to get the current TickLeiste from server. The server on its own will only
+send incremental updates.
+
+
+### ChangeNameR
+This is used to change the name of a Player without moving them.
+```
+{
+"RequestType" : "ChangeNameR",
+"Player" : <KnownPlayer>
+}
+```
+If you don't set the name in KnownPlayer no namechange will occur.
+
+## Events
+A Server might Send the following Events to a client.
+
+### SetPlayerTickE
+```
+{
+"EventType" : "SetPlayerTickE",
+"Player" : <KnownPlayer>
+"Tick" : <Tick>
+}
+```
+
+### InitializeTickLeisteE
+```
+{
+"EventType" : "InitializeTickLeisteE",
+"TickLeiste" : <KnownTickLieste>
+}
+```
