 Important facts:
 - techage is not backwards compatible and cannot be installed on a server together with TechPack
 - techage is significantly more extensive, since additional mods are integrated
-- techage represents 4 technological ages:
+- techage represents 5 technological ages:
   - Iron Age (TA1) - simple tools like coal pile, coal burner, gravel sieve, hammer for getting ores and making goods
   - Steam Age (TA2) - Simple machines that are powered by steam engines and drive axles
   - Oil Age (TA3) - More modern machines that are powered by electricity.  
-   The electricity is generated by coal & oil power plants. The oil must be explored, extracted and transported.
-  - Future Age (TA4) - Electricity from renewable energy sources such as sun and wind.  
-   Environmentally friendly electricity storage, intelligent machines and means of transport of the future
+  - Present (TA4) - Electricity from renewable energy sources such as sun and wind.
+  - Future (TA5) - Machines to overcome space and time, new sources of energy and other achievements.
 - Since the levels build on each other, all ages have to be run through one after the other
 
 In contrast to TechPack, the resources are more limited and it is much more difficult to pass all levels.
 (no endless ore generation by means of cobble generators)
 
+**Techage blocks store information outside of the block. This is for performance reasons.
+If you move, place, or remove blocks with any tool, at best, only the information is lost.
+In the worst case, the server crashes.**

+
+Techage API function to adapt/prepare techage for other mods/games.
+
+
+
+## Move/Fly Controller
+
+Register node names for nodes allowed to be moved by fly/move controllers.
+
+This is only necessary for undiggable/intelligent nodes with one of the following attributes:
+
+- ```drop = ""```
+- ```diggable = false```
+- ```after_dig_node ~= nil```
+
+```lua
+techage.register_simple_nodes(node_names, is_valid)
+```
+
+- `is_valid = true`  - Add node to the list of simple nodes
+- `is_valid = false`  - Remove node from the list of simple nodes
+
+Example:
+
+```lua
+techage.register_simple_nodes({"techage:power_lineS"}, true)
+```
+
+For door nodes used as sliding doors by means of the move controller, call in addition:
+
+```lua
+techage.flylib.protect_door_from_being_opened(node_name)
+```
+
+
+
+## TA1 Hammer
+
+Register stone/gravel name pair for the hammer blow:
+
+```lua
+techage.register_stone_gravel_pair(stone_name, gravel_name)
+```
+
+Example:
+
+```lua
+techage.register_stone_gravel_pair("default:stone", "default:gravel")
+```
+
+
+
+## TA1 Melting Pot
+
+Register a pot recipe:
+
+```lua
+techage.ironage_register_recipe(recipe)
+```
+
+Examples:
+
+```lua
+techage.ironage_register_recipe({
+	output = "default:obsidian",
+	recipe = {"default:cobble"},
+	heat = 10,	-- Corresponds to the tower height
+	time = 8,	-- Cooking time in seconds
+})
+techage.ironage_register_recipe({
+	output = "default:bronze_ingot 4",
+	recipe = {"default:copper_ingot", "default:copper_ingot", "default:copper_ingot", "default:tin_ingot"},
+	heat = 4,	-- Corresponds to the tower height
+	time = 8,	-- Cooking time in seconds
+})
+```
+
+
+
+## TA2/TA3/TA4 Autocrafter
+
+Register any nodes/items that should not be crafted via the autocrafter.
+
+```lua
+techage.register_uncraftable_items(item_name)
+```
+
+
+
+## TA2/TA3/TA4 Gravel Sieve
+
+Change the probability of ores or register new ores for sieving. 
+
+```lua
+techage.register_ore_for_gravelsieve(ore_name, probability)
+```
+
+Example:
+
+```lua
+techage.register_ore_for_gravelsieve("default:iron_lump", 30)
+```
+
+Default values for MTG are:
+
+```lua
+-- higher value means less frequent occurrence
+techage:baborium_lump    100000  -- hardly ever
+default:mese_crystal     548     -- every 548th time
+default:gold_lump        439

+
+## TA2/TA3/TA4 Gravel Rinser
+
+Add a rinser recipe.
+
+```lua
+techage.add_rinser_recipe(recipe)
+```
+
+Example:
+
+```lua
+techage.add_rinser_recipe({input = "techage:sieved_gravel", output = "techage:usmium_nuggets", probability = 30})
+```
+
+
+
+## TA2/TA3/TA4 Grinder
+
+Add a grinder recipe.
+
+```lua
+techage.add_grinder_recipe(recipe, ta1_permitted)
+```
+
+Examples:
+
+```lua
+echage.add_grinder_recipe({input = "default:cobble", output = "default:gravel"})
+techage.add_grinder_recipe({input = "default:sandstone", output = "default:sand 4"})
+```
+
+
+
+## TA3/TA4 Electronic Fab, TA4 Doser
+
+Add recipes to an electronic fab or doser (chemical reactor):
+
+
+```lua
+techage.recipes.add(rtype, recipe)
+```
+
+`rtype` is one of: `ta2_electronic_fab` , `ta4_doser`
+
+A recipe look like:
+
+```
+{
+    output = "<item-name> <units>",  -- units = 1..n
+    waste = "<item-name> <units>",   -- units = 1..n
+    input = {                        -- up to 4 items
+        "<item-name> <units>",
+        "<item-name> <units>",
+    },
+}
+```

+    "\n"..
+    "  - Isolierte Kabel (TA Stromkabel) für die lokale Verkabelung im Boden oder in Gebäuden. Diese Kabel lassen sich in der Wand oder im Boden verstecken (können mit der Kelle \"verputzt\" werden).\n"..
+    "  - Überlandleitungen (TA Stromleitung) für Freiluftverkabelung über große Strecken. Diese Kabel sind geschützt\\, können also von anderen Spielern nicht entfernt werden.\n"..

+    "Wird zu wenig Strom bereitgestellt\\, gehen die Verbraucher aus.\n"..
+    "In diesem Zusammenhang ist auch wichtig\\, dass die Funktionsweise von Forceload Blöcken verstanden wurde\\, denn bspw. Generatoren liefern nur Strom\\, wenn der entsprechende Map-Block geladen ist. Dies kann mit einen Forceload Block erzwungen werden.\n"..
+    "\n"..
+    "In TA4 kommt noch ein Kabel für die Solaranlage hinzu.\n"..
+    "\n"..
+    "\n"..
+    "\n",
+    "Speichersysteme im Stromnetz erfüllen zwei Aufgaben:\n"..
+    "\n"..
+    "  - Um Bedarfsspitzen abzufangen: Alle Generatoren liefern immer gerade soviel Leistung\\, wie benötigt wird. Werden aber Verbraucher ein/ausgeschaltet oder kommt es aus anderen Gründen zu Bedarfsschwankungen\\, so können Verbraucher kurzzeitig ausfallen. Um dies zu verhindern\\, sollte immer mindestens ein Akkublock in jedem Netzwerk vorhanden sein. Dieser dient als Puffer und gleicht diese Schwankungen im Sekundenbereich aus.\n"..
+    "  - Um regenerative Energie zu speichern: Solar und Wind stehen nicht 24 Stunden am Tag zur Verfügung. Damit die Stromversorgung nicht ausfällt\\, wenn kein Strom produziert wird\\, müssen ein oder mehrere Speichersysteme im Netzwerk verbaut werden. Alternativ können die Lücken auch mit Öl/Kohle-Strom überbrückt werden.\n"..
+    "\n"..
+    "Ein Speichersystem gibt seine Kapazität in kud an\\, also ku pro day (Tag). Bspw. ein Speichersystem mit 100 kud liefert 100 ku einen Spieltag lang\\, oder auch 10 ku für 10 Spieltage.\n"..
+    "\n"..
+    "Alle TA3/TA4 Energiequellen besitzen eine einstellbare Ladecharakteristik. Standardmäßig ist diese auf \"80% - 100%\" eingestellt. Dies bedeutet\\, dass die Leistung ab 80% Füllung des Speichersystems immer weiter reduziert wird\\, bis sie bei 100 % komplett abschaltet. Sofern Strom im Netzwerk benötigt wird\\, werden die 100 % nie erreicht\\, da die Leistung des Generators irgendwann auf den Strombedarf im Netzwerk abgesunken ist und damit das Speichersystem nicht mehr geladen\\, sondern nur noch die Verbraucher bedient werden.\n"..
+    "\n"..
+    "Dies hat mehrere Vorteile:\n"..
+    "\n"..
+    "  - Die Ladecharakteristik ist einstellbar. Damit kann man bspw. Öl/Kohle Energiequellen bei 60% und die regenerativen Energiequellen erst bei 80% zurückfahren. Damit wird nur Öl/Kohle verbrannt\\, wenn nicht ausreichend regenerativen Energiequellen zur Verfügung stehen.\n"..
+    "  - Mehrere Energiequellen können parallel betrieben werden und werden dabei nahezu gleichmäßig belastet\\, denn alle Energiequellen arbeiten bspw. bis 80% Ladekapazität des Speichersystems mit ihrer vollen Leistung und fahren dann gleichzeitig ihre Leistung zurück.\n"..
+    "  - Alle Speichersysteme in einem Netzwerk bilden einen großen Puffer. An jedem Speichersystem aber auch am Strom Terminal kann immer die  Ladekapazität und der Füllungsgrad des gesamten Speichersystems in Prozent abgelesen werden.\n"..

+    "TA3 has 2 types of power cables:\n"..
+    "\n"..
+    "  - Insulated cables (TA power cables) for local wiring in the floor or in buildings. These cables can be hidden in the wall or in the floor (can be \"plastered\" with the trowel).\n"..
+    "  - Overland lines (TA power line) for outdoor cabling over long distances. These cables are protected and cannot be removed by other players.\n"..
+    "\n"..
+    "Several consumers\\, storage systems\\, and generators can be operated together in a power network. Networks can be set up with the help of the junction boxes.\n"..
+    "If too little electricity is provided\\, consumers run out.\n"..
+    "In this context\\, it is also important that the functionality of Forceload blocks is understood\\, because generators\\, for example\\, only supply electricity when the corresponding map block is loaded. This can be enforced with a forceload block.\n"..
+    "\n"..
+    "In TA4 there is also a cable for the solar system.\n"..
+    "\n"..
+    "\n"..
+    "\n",
+    "Storage systems in the power grid fulfill two tasks:\n"..
+    "\n"..
+    "  - To cope with peaks in demand: All generators always deliver just as much power as is needed. However\\, if consumers are switched on/off or there are fluctuations in demand for other reasons\\, consumers can fail for a short time. To prevent this\\, there should always be at least one battery block in every network. This serves as a buffer and compensates for these fluctuations in the seconds range.\n"..
+    "  - To store regenerative energy: Solar and wind are not available 24 hours a day. So that the power supply does not fail when no electricity is produced\\, one or more storage systems must be installed in the network. Alternatively\\, the gaps can also be bridged with oil/coal electricity.\n"..
+    "\n"..
+    "A storage system indicates its capacity in kud\\, i.e. ku per day. For example\\, a storage system with 100 kud delivers 100 ku for one game day\\, or 10 ku for 10 game days.\n"..
+    "\n"..
+    "All TA3/TA4 energy sources have adjustable charging characteristics. By default this is set to \"80% - 100%\". This means that when the storage system is 80% full\\, the output is reduced further and further until it switches off completely at 100%. If electricity is required in the network\\, 100% will never be reached\\, since the power of the generator has at some point dropped to the electricity demand in the network and the storage system is no longer charged\\, but only the consumers are served.\n"..
+    "\n"..
+    "This has several advantages:\n"..
+    "\n"..
+    "  - The charging characteristics are adjustable. This means\\, for example\\, that oil/coal energy sources can be reduced at 60% and regenerative energy sources only at 80%. This means that oil/coal is only burned if there are not enough renewable energy sources available.\n"..
+    "  - Several energy sources can be operated in parallel and are loaded almost evenly\\, because all energy sources work\\, for example\\, up to 80% of the storage system's charging capacity at their full capacity and then reduce their capacity at the same time.\n"..
+    "  - All storage systems in a network form a large buffer. The charging capacity and the filling level of the entire storage system can always be read in percent on every storage system\\, but also on the electricity terminal.\n"..
+    "\n"..
+    " \n"..
+    "\n",
+    "For local wiring in the floor or in buildings.\n"..
+    "Branches can be realized using junction boxes. The maximum cable length between machines or junction boxes is 1000 m. A maximum of 1000 nodes can be connected in a power network. All blocks with power connection\\, including junction boxes\\, count as nodes.\n"..
+    "\n"..
