Introduction and Warning
This Don't Starve Together guide was prepared to help those who are new to the game and find themselves saying "I keep dying instantly" or "Autumn is great but the other seasons totally ruin it."
If you're not saying those things but still playing, keep reading for tips on transitioning between seasons and preparing for them in advance. But I have an important warning first:
Warning! This post contains spoilers about the game!
Dear Don't Starve Together enthusiast, since we've gotten this far, let's dive right in. We'll proceed assuming that none of the game's features have been changed from their defaults.
Gathering Resources in Autumn
You've entered the game and you're standing next to the portal. The season is Autumn, our favorite season, because there are no challenging weather conditions to deal with. First, we start running around to find a grassy area. While running around, we need to collect every flint, grass and twig we come across. 
Don't think 10-15 of each will be enough. Don't even bother reading the rest of this guide until you've collected at least 40 of each, GO! While you're on the move, if you spot any rocks, craft a pickaxe (from the 'tool' tab at the top of the left-hand menu) to break them and collect stone. Once you've done that, we can move on calmly.
You'll notice that running along roads lets you move much faster. The moment you have a flint and 1-2 twigs, craft an axe and start chopping wood. If possible, chop down the larger birchnut trees, since the birchnuts that drop from them are great for filling your stomach early in the game. (You can cook and eat birchnuts over the campfire you'll light in the evening.)
When evening comes, set up a fire somewhere in the middle of the trees to make the most of every hour. During the two hours you'll spend waiting by the fire until morning, keep on chopping wood.
Once you've gathered enough of everything, at least 40 each of wood, flint, grass, twigs, and stone (when collecting stone, prioritize the gold-veined rocks shown below, since they also yield gold) we can start looking for beefalo.
The Ideal Camp Location: Beefalo, Spiders, and Pigs
The ideal camp location is a corner or edge area that isn't too far from beefalo, spiders, and pigs. The reason for choosing a corner or edge is simple: when hounds attack, you'll know which direction they're coming from. This is actually one of the most critical points in this Don't Starve Together guide.
Beefalo because we'll always need their fur and especially their manure. Also, when hounds show up, we run toward the beefalo, and while we're running circles around them, the beefalo take out the hounds. (During nighttime hound attacks, always make sure you have at least 3 torches on hand.)
Spiders are one of our most important resources. Using traps, which we can craft from the survival tab with 2 twigs and 6 grass, we head over near a spider den. It's critical that you never attack the spiders directly. If you do, "warrior spiders" (the green ones) come pouring out of the den; they can leap at you and deal serious damage.
Pay attention to how many tiers the spider den has. However many tiers it has, that's how many black spiders will emerge when you step into its web zone. In the photo below, it's a three-tier den, so we prepare three traps accordingly. (Place the traps at the far edge of the web zone.)
The moment you step into the web, three spiders will come out; if you wait calmly behind the traps, they'll get caught on their own and you'll get silk, monster meat, and glands without lifting a finger. These are essential materials for keeping your camp running, so never destroy spider dens.
The only ones you can destroy are three-tier dens like the one in the photo, because those eventually spawn a spider queen, and she can do quite a bit of damage before she sets up a new den.
Besides beefalo and spiders, there are also pigs near our camp. So what are our little pig friends good for? If you feed them food (monster meat works, as do foods that are starting to spoil...) they'll follow you around and do whatever you're doing.
For example, it's a great solution for chopping wood quickly, but if you chop too many trees, watch out for the treeguards that appear! (To get treeguards to leave you alone, keep pine cones in your inventory; planting 8-9 pine cones will calm them down.)
Also, if you feed flowers to pigs, they'll drop manure for you, which can be really handy if you're running low on beefalo manure. Alright, let's set up camp!
Don't Starve Together Guide: Setting Up Camp
Our first priorities are: a science machine (1 gold, 4 wood, 4 stone), a firepit (2 wood, 12 stone), and a crock pot (9 stone converted to 3 cut stone via the science machine, 6 coal, and 6 twigs). To get coal, you can set fire to trees that don't have anything nearby using a torch. Then when you chop them down with an axe, you'll get at least one coal.
In the crock pot, we can combine 4 types of food to make meals that boost hunger, sanity, and HP. For all recipes, check out the official wiki: Don't Starve Together Crock Pot Recipe Guide
When using monster meat from spiders, put no more than one piece in the crock pot; fill the other three slots with berries or carrots (any fruit or vegetable will do) and you can make meatballs. Meatballs are our staple food, we love meatballs.
Now that you've covered your basic needs, we can move on to more detailed topics. By using the science machine to craft a shovel, you can dig up all the nearby berry bushes by the roots and replant them close to your camp for a steady berry supply. After replanting, don't forget to fertilize them with manure!
Crafting chests out of wood will help you stay far more organized. When you have the materials, if you also build an Alchemy Engine (science tab, 4 boards, 2 cut stone, 6 gold), the number of items you can craft will increase dramatically. For example, the tent (6 silk, 4 twigs, and 3 rope) which is incredibly useful for quickly restoring both sanity and HP, is crafted with the alchemy engine.
Everything's ready, you're comfortable... But do you feel like you're starting to get a little chilly? Don't forget. Winter arrives on Day 20! For other game guides, feel free to check out our gaming articles.
Preparing for Winter
For Winter:
Thermal stones are everything. We craft a thermal stone using 10 stone, a pickaxe, and 3 flint, then heat it up by the fire at night; when we're moving around with a heated (orange-colored) thermal stone, it keeps us warm. Its temperature is indicated by its color. There's a color scale ranging from orange to white (hot to cold): 
Besides the thermal stone, crafting a winter hat from 4 beefalo fur and 4 spider silk will make sure we're well covered in winter. Of course, it's even easier if you shear the beefalo during autumn before winter arrives. To do this, approach the beefalo at night (don't forget your torches!) with a razor in hand and shear their fur. Make sure they're not in mating season. Even if they're asleep, if they're in a mating frenzy they can wake up and attack.
Lastly, since you won't be able to find fruits and vegetables, stock up on plenty of ice. You can use ice alongside monster meat to make meatballs throughout winter.
In hopes that you've already built an ice box (1 board, 1 gear, 2 gold) by this point to keep your ice and produce fresh for longer. Also, build a drying rack (3 twigs, 2 coal, 3 rope) to dry any meat that isn't monster meat, dried meat lasts a very long time and does wonders for your sanity.
Preparing for Spring
For Spring:
If anyone is cheering "the hardest part is behind us" after surviving winter, we can have a good laugh at them right about now. No season in this game is as frustrating as Spring. It will rain constantly and restoring your sanity will be extremely difficult.
The most important thing for this season is building lightning rods around your camp using 3 gold and 1 cut stone each. If you don't, lightning will strike and everything in your camp risks burning to the ground.
There's also a straw hat you can craft with 12 grass that provides at least some protection from the rain. Beyond that, there's also a rain hat and rain coat (you can find them in the dress tab), but the tentacle spots required for the rain coat in particular are a very hard material to come by.
My advice for the whole of Spring: keep your sanity as high as possible and wait for the season to pass. For more on survival mechanics, check out our game guides. The official Don't Starve Together wiki is also always a helpful resource: Don't Starve Together Wiki
Preparing for Summer
For Summer:
Just when you think you're finally free from the rain, you'll realize you can barely move around outside from the heat. Not even a breeze at night...
Your salvation: the endothermic fire pit. You'll need to build an endothermic fire pit at your camp using 2 nitre, 4 cut stone, and 2 electrical doodads. From now on, you'll use this instead of a regular fire all summer long.
While out and about, you can also craft temporary mini endothermic fires using 2 nitre and 3 grass. You can also build a siesta lean-to (2 silk, 4 boards, 3 rope) to use during the day and shield yourself from the sun. Honestly though, as long as you have the endothermic fire pit and manage to keep your sanity in check, it's not strictly necessary.
Thermal stones come into play here as well: once you put your thermal stone in the ice box and it turns white, it drops to -20 degrees and can keep you cool for a while. You can also craft a huge ice cube to wear on your head (2 electrical doodads, 4 rope, 10 ice), though over time it can leave you soaking wet.
Another option is the chilled amulet, craftable with 3 gold and 1 blue gem. But to make that, you'll need to build a prestihatitator first, let's not go down that rabbit hole right now.
With all this knowledge, you can now usher in Autumn again. Autumn, our favorite season. You're doing great, you've made it through a full year! Now you can spread your wings and fly through the world of Don't Starve Together, discovering the million details this Don't Starve Together guide couldn't begin to cover.
Never stop collecting stuff!
