+# Section 9: Skin Design and Auto-smelters
+
+## Skin Design
+
+This section is pretty straightforward thanks to the great tools at [Miners Need Cool Shoes](http://www.needcoolshoes.com/). Go to needcoolshoes.com and import your skin or go to the gallery and pick a new one to tweak. Then edit that skin using their editing tools! You can download the png file or change your skin right from the site. You can even combine skins by loading multiple skins as layers in the editing tool.
+
+## Auto-smelters
+
+The concept behind an auto-smelter is pretty simple: smelt a chest full of materials automatically. The build in its most basic is this: Chest (with materials) feeds into a hopper, which in turn feeds into the furnace, then into another hopper, then into the chest with the final product.
+
+![](images/auto-smelt.png)
+
+Think of ways to improve upon this design by making it more efficient, easier to load with raw materials or have more capacity.

+Villagers are passive mobs that live in villages (naturally generated groups of buildings). They work at their jobs, breed, and interact with each other. They spawn unemployed, but can be given jobs by placing a job site block near them (there must be a job site block for every employed villager). To learn more about villagers, check out [the wiki](https://minecraft.fandom.com/wiki/Villager) (https://minecraft.fandom.com/wiki/Villager).

-After placing down some track, you can place a minecart on top and right-click to enter. Once you're in the cart, pressing W will start moving you forward. Pressing the left SHIFT key will make you dismount the minecart, although it will keep moving. The wooden block at the end of this track stops the minecart before it goes too far:
+For 2 villagers to breed, a couple of conditions must be met:
+* The building where the villagers will breed must have at least three beds with two or more empty blocks above them
+* The villagers must have 3 loaves of bread, 12 carrots, 12 potatoes, or 12 beetroots in their inventory (you can give them this food by throwing it to them)
 
-<img src="images/minecart_riding.png" style="width:50%">
+If these conditions are met, the villagers should breed in around 20 minutes. Once they have bred, a new, unemployed baby villager will appear. Baby villagers cannot trade; you will have to wait 20 minutes until they grow up to trade with them.
 
-You can use powered rails to keep the minecart going on long tracks, similar to redstone repeaters. They must be powered with redstone to provide any power to the minecart.

-By using blocks to create tilted rails, we can make handy locations for starting minecarts without having to move manually.
+There are many kinds of villagers who provide different opportunities for trading. The types of villagers and their respective job site blocks and trades are:
 
-<img src="images/minecart_launcher.png" style="width:50%">
+| Villager | Job Site Block | Trades |
+| ----------- | ---------------- | ---- |
+|Nitwit | n/a | n/a |
+|Unemployed | n/a | None until employed |
+|Armorer | Blast Furnance | Trades foundry items and sells chain, iron and enchanted diamond armor tiers|
+|Butcher | Smoker | Trades meats, sweet berries, rabbit stew, and dried kelp blocks |
+|Cartographer | Cartography Table| Trades banners, compasses, banner patterns, papers and various maps, including explorer maps|
+|Cleric | Brewing Stand | Trades magic items like ender pearls, redstone dust, glowstone dust, and other enchanting or potion ingredients|
+|Farmer | Composter | Trades crops and natural foods, such as bread|
+|Fisherman | Barrel | Trades campfires and fishing items|
+|Fletcher | Fletching Table | Trades bows, crossbows, arrows|
+|Leatherworker| Cauldron | Trades scutes, rabbit hide, and leather-related items|
+|Librarian | Lectern | Trades enchanted books, clocks, compasses, name tags, glass, ink sacs, lanterns, and book and quills|
+|Mason | Stonecutter | Trades polished stones, terracotta, clay, glazed terracotta and quartz|
+|Shephard | Loom | Trades shears, wool, dyes, paintings and beds|
+|Toolsmith | Smithing Table | Trades minerals, bells and harvest tools|
+|Weaponsmith | Grindstone | Trades minerals, bells and enchanted melee weapons|
 
-Redstone can also be used to make junctions where you can select which direction the cart will take you. Three-way intersections will flip back and forth as power is supplied or cut off.
+## Example Trades

+### Weaponsmith
 
-We can also make a two-way minecart station where our minecart will stop until we tell it to continue. Dig out a 3x1 trench. Put a detector rail in the middle, and two powered rails on either side (powered rails act as brakes when unpowered).

-<img src="images/stop_initial.png" style="width:50%">
+As you continue to trade with a villager, they will advance in the types of items they will trade. For example, a weaponsmith will start with just trading for two items:
 
-Extend the rails outward to connect to your normal railways. Place two blocks with buttons on them on top of the blocks adjacent to the powered rail segments. When you press the button, the powered rail below it should light up.

+Eventually, more trades open up:
 
-When you are on the railway, you will stop right next to one of the buttons. Press the button to power the rail underneath you, pushing you forward. The detector rail will then power the rail on the other side, pushing you along on your journey.

-# Section 8: Mob Farm/Grinder
+# Section 7: The Nether
 
-Occasionally you will find a monster spawner in a Minecraft dungeon. These cage-like blocks spawn monsters in a cube around them every few seconds. While they can be dangerous, they can also be a valuable source of items and experience. To do so safely and quickly, you can build a structure that serves two purposes. First, it should weaken the monsters using water, lava, or a steep fall so that you can defeat them faster. Second, it should also allow you to attack the spawned monsters from a safe place.
+## Nether Portals
 
-You must locate a monster spawner! They're locating in dungeons and are surrounded by stone brick rather than smooth stone. When you find it, dig out a large space around the spawner (about 8x8) and put torches around it so monsters won't spawn.
+The Nether is an awful place without much to see and a lot to be afraid of, but it also a place one must visit if one is ever to create potions or create beacons. It is also fairly handy when traveling long distances.
 
-<img src="images/section_2/grinder_initial.png" style="width:600px">
+This section is going to focus on placing nether portals for maximum transportation value with maximum safety features.
 
-The goal for this mob grinder is to drop zombies exactly 22 steps (check out the Minecraft wiki to calculate how high you should drop each type of monster). After the drop, they will have low enough health that one hit from a sword will kill them. At the same time, the player must be able to stand near enough the spawner that new zombies will spawn. First, we need to force the monsters into one location so we can control where they go. Dig out some of the stone on one side (see the picture for reference) and then put water at the middle and corners of the other side (underneath the glowstone in the second picture).
+Going through a nether portal will create a linked portal in the nether. If there is already an active portal within range (about 128 blocks) in the other world, the portal will link to it.

-Next, we will dig a shaft upward 22 blocks (we built ours out of glass so you can easily see how it is built). Inside, we will use a water-and-sign checkerboard to get the zombies to swim up to the top. The air pockets will keep the zombies alive while they swim upward.
+* Take flint and steel. Your portal might be damaged by ghasts. In this exercise, you'll need it to light a new portal at the 2nd location.

-Third, we need to build a horizontal tunnel with water at one end to push the zombies to the top of our drop shaft. Place one more water source next to the top sign so that it pushes the zombies over the spawner to the opposite side. Another sign at the end will stop the water where we want it for the drop shaft.
