This is a step by step tutorial for how to craft the new cool items and find the ores 

Step 1 

How to find the ores (you have to smelt ores marked in yellow)

Exploring the end: enderium, rhodonite, maradonyx, moonstone, obsidian nuggets, serpentine, larimar, white diamond, purple diamond, cyber crystal, Xernium, neon Meteorite scraps, cobalt, pearl, orichalcum and pottasium

Exploring the nether: fire opal (nether waste and crimson forest), catseye (warped forest) green catseye (warped forest), pyrite (nether wastes), sulfur (nether wastes), ghoul quartz (soul sand valley), blood quartz (soul sand valley), Sunstone (nether wastes and netherwart forest), blood stone (nether wastes and netherwart forest), Yurium (nether wastes and netherwart forest), palladium (nether wastes), Humoranium (soul sand valley), Anti-Humoranium (soul sand valley), bixbite, red diamond (nether wastes), orange diamond (crimson forest and nether wastes), pink diamond, pelenium (nether wastes) , meteorite scraps (nether wastes)(soul sand valley), seaborgium (nether wastes) and soul quartz (soul sand valley) 

Crafting: dragon scales, obsidian nuggets, Simonium, ikegamium, Ikegamonium, ikegamini, simoganium, blackstone, whitestone, snowflake obsidian, plutonium, meteorite ingot, hydrated pottasium (item,armor,tools,block), neon Meteorite ingot, unoptanium and nether gold 

Smelting: smelt iron to get steel       

Keep smelting zircon to get the color you are looking for        

smelt cinnabar to get quicksilver

Fusing: you can fuse gemstones together in a brewing stand but make sure that you only put one gem in each slot of the bottom row otherwise it will not work!

Thats how to get the ores 

Step 2 weapons 

You can craft a sword with any ore and you can also craft swords now from emerald and lapis but it all works a bit differently:

If you want to make a sword, axe or pickaxe (you can not make a sword with meteorite scrap) (you can't make an axe with cyber crystal, corrupted cyber crystal, cobalt, all new pearls, obsidian nuggets, meteorite scrap, plutonium and unoptanium) (you can not make a pickaxe with meteorite scrap, plutonium, unoptanium, obsidian nuggets, chloronium, cyber crystal, corrupted cyber crystal, cobalt, all new diamonds, all new pearls and all catseye except for normal catseye)

You first need a item called obsidian nuggets there are 2 ways to get obsidian nuggets 

1. Put obsidian in a crafting table
2. Find obsidian ore in the new end dimension

Now put these obsidian nuggets in a vertical line from bottom left to up right in the crafting table and you get obsidian sticks 

 you can make a sword, axe, hoe, shovel or pickaxe of any gem now with the regular minecraft sword recipe except instead of a normal stick you use a obsidian stick. 

There are a few exceptions because metals have a different recipe instead of using obsidian nuggets to make a obsidian stick you use iron nuggets to make a iron stick 

You can know when something is a metal when it has the same shape as iron 

If an ore is found in the nether you need blaze rods to craft a sword or axe out of it (except for green catseye, meteorite, red diamond, orange diamond and pink diamond)

This is how you get galaxy's edge swords (Lightsabers) you can use different gems to get different colours just use a: ruby, sardonyx, citrine, peridot, sapphire, tanzanite, amethyst shard, iolite, onyx, goshenite, kunzite, chrysolite, cyber crystal, rose quartz, smoky quartz, garnet, hackmantite, coal, tourmaline, topaz, quicksilver, prism, spinel, indigolite, bixbite, diamond or jade instead of a peridot. You can also use a corrupted cyber crystal instead of a normal one to get galaxy's edge swords with shadow cores they will also do more damage

These are some extra powerfull swords:

The uranium and titanium sword: you craft it by doing uranium up top titanium in the middle and a iron stick at the bottom 

You can go a step further by obtaining adamantite and mythril with fusion:

catseye + uranium = adamantite and 

soul quartz + titanium = mythril

and with those you can make the adamantite and mythril blade mythril up top adamantite at the middle and a iron stick at the bottom 

Crafting tree for strongest sword:

Step 3 armor 

You can't make armor from every ore 

These are the ores you can not make armor out of: obsidian shard, plutonium, unoptanium, all pearls, all dusts, aluminium, fire opal, soul quartz, all catseye/tigerseye variants, quicksilver, ghoul quartz, blood quartz, cinnabar, (corrupted) cyber crystal, grandidierite, (neon) meteorite scrap, solar diamond, eclipse diamond, sulfur, all star sapphires, star ruby, chalcanthite, stibnite, all zircons, matrix opal, hercynite, radium and seaborgium 

You just craft armor like normally in minecraft. 

Making Blocks: 

Making Blocks is super easy it just works like how it normally works in Minecraft: 9X the item you want to make a block out of in the crafting table. Some ores do not have block variants mainly ores with a lot of different colours and really rare ores

This was the tutorial if you still don't know how to craft something or forget you can always look in the recipe book. 

Some more new things the addon adds: 

New trees that grow in the end.
