+**Shared Plex servers configuration**
+
+plexPlayer can be configured in multiple ways, achieving the same thing:
+
+```
+entity:
+  plexPlayer: TV 2020
+```
+
+```
+entity:
+  plexPlayer:
+    - TV 2020
+```
+
+```
+entity:
+  plexPlayer:
+    identifier: TV 2020
+```
+
+```
+entity:
+  plexPlayer:
+    - identifier: TV 2020
+```
+
+As can be seen from the last two examples, it is possible to configure it as an object having key "identifier".
+
+That is useful, if you want to stream media from shared or remote Plex server. Add information about your local Plex server which sees your device on which you wish to play content. This is done by including a new key, "server" having additional keys:
+
+Example 1:
+
+```
+entity:
+  plexPlayer:
+    - identifier: TV 2020
+      server:
+        ip: 192.168.13.37 # Mandatory
+        token: QWdsqEXAMPLETOKENqwerty # Mandatory
+        port: 32400
+        protocol: http
+```
+
+Example 2:
+
+```
+entity:
+  plexPlayer:
+    - identifier: TV 2020
+      server:
+        ip: 192.168.13.37 # Mandatory
+        token: QWdsqEXAMPLETOKENqwerty # Mandatory
+        port: 32400
+        protocol: http
+```
+
 ## Sorting
 
 You can use _:desc_ or _:asc_ after every value to change the order from ascending to descending. For example, titlesort would become titleSort:asc, or titleSort:desc.
