+### TA4 Move Controller
+
+Der TA4 Move Controller ist ähnlich zum "Door Controller 2", aber die ausgewählten Blöcke werden nicht entfernt, sondern können bewegt werden.
+Da die bewegten Blöcke Spieler und Mobs mitnehmen können, die auf dem Block stehen, können damit Fahrstühle und ähnliche Transportsysteme gebaut werden.
+
+Anleitung:
+
+- Controller setzen und die Blöcke, die bewegt werden sollen, über das Menü an-trainieren (Es können bis zu 16 Blöcke an-trainiert werden)
+- die "Flugstrecke" muss über eine x,y,z Angabe (relativ) eingegeben werden (die maximale Distanz beträgt 100 m)
+- mit den Menü-Tasten "Bewege A-B" sowie "Bewege B-A" kann die Bewegung getestet werden
+- man kann auch durch Wände oder andere Blöcke fliegen
+- auch die Zielposition für die Blöcke kann belegt sein. Die Blöcke werden in diesem Falle "unsichtbar" gespeichert. Dies ist für Schiebetüren und ähnliches gedacht
+- Über das Gabelschlüssel-Menü kann im Controller auch ein "handover" programmiert werden. Durch Eingabe einer Blocknummer werden die Blöcke dann an den nächsten Move Controller übergeben. So lassen sich auch zusammenhängende Bewegungen über mehrere Move Controller  realisieren.
+
+Der Move Controller unterstützt folgende techage Kommandos:
+
+- `a2b`  Bewege Block von A nach B
+- `b2a`  Bewege Block von B nach A
+- `move` Bewege Block auf die andere Seite

+### TA4 Sequenzer
+
+über den TA4 Sequenzer können ganze Abläufe programmiert werden. Hier ein Beispiel:
+
+```
+-- this is a comment
+[1] send 1234 a2b
+[30] send 1234 b2a
+[60] goto 1
+```
+
+- Jede Zeile beginnt mit einem Nummer, welche einem Zeitpunkt entspricht `[<num>]`
+- Für Zeitpunkte sind Werte von 1 bis 50000 zulässig
+- 1 entspricht 100 ms, 50000 entspricht in etwa 4 Spieltagen
+- Leerzeilen oder Kommentare sind erlaubt (`-- comment`)
+- Mit `send <num> <command> <data>` kann man ein Kommando an einen Block senden
+- Mit `goto <num>` kann man an eine andere Zeile/Zeitpunkt springen
+- Mit `stop` kann man den Sequenzer verzögert stoppen, so dass er kein neues Kommando
+  von einem Taster oder anderem Block annimmt (um eine Bewegung abzuschließen)
+  Ohne `stop` geht der Sequenzer sofort nach dem letzten Kommando in den stopped Modus.
+
+Der TA4 Sequenzer unterstützt folgende techage Kommandos:
+
+- `goto <num>`  Zu einer Kommandozeile springen und damit den Sequenzer starten
+- `stop`  Den Sequenzer anhalten
+

+### TA4 Move Controller
+
+The TA4 Move Controller is similar to "Door Controller 2", but the selected blocks are not removed, but can be moved.
+Since the moving blocks can take players and mobs standing on the block with them, elevators and similar transport systems can be built with them.
+
+Instructions:
+
+- Set the controller and train the blocks to be moved via the menu (up to 16 blocks can be trained)
+- the "flight route" must be entered via an x, y, z specification (relative) (the maximum distance is 100 m)
+- The movement can be tested with the menu buttons "Move A-B" and "Move B-A"
+- you can also fly through walls or other blocks
+- The target position for the blocks can also be occupied. In this case, the blocks are saved "invisibly". This is intended for sliding doors and the like
+- A "handover" can also be programmed in the controller via the open-ended wrench menu. By entering a block number, the blocks are then transferred to the next move controller. In this way, connected movements can also be implemented using several Move Controllers.
+
+The Move Controller supports the following techage commands:
+
+- `a2b` Move block from A to B.
+- `b2a` Move block from B to A.
+- `move` Move block to the other side
+
+[ta4_movecontroller|image]
+
+### TA4 Sequencer
+
+Entire processes can be programmed using the TA4 sequencer. Here's an example:
+
+```
+-- this is a comment
+[1] send 1234 a2b
+[30] send 1234 b2a
+[60] goto 1
+```
+
+- Each line begins with a number which corresponds to a point in time `[<num>]`
+- Values from 1 to 50000 are permitted for times
+- 1 corresponds to 100 ms, 50000 corresponds to about 4 game days
+- Empty lines or comments are allowed (`-- comment`)
+- With `send <num> <command> <data>` you can send a command to a block
+- With `goto <num>` you can jump to another line / point in time
+- With `stop` you can stop the sequencer with a delay so that it does not receive a new command
+  accepts from a button or other block (to complete a movement)
+  Without `stop`, the sequencer goes into stopped mode immediately after the last command.
+
+The TA4 sequencer supports the following techage commands:
+
+- `goto <num>` Jump to a command line and start the sequencer
+- `stop` Stop the sequencer
+
+The `goto` command is only accepted when the sequencer is stopped.
