Summarize the following:
This allows you to determine how many pavers to buy, as well as how much of the other supplies you will need. You need to have a clear idea of what you want your patio to look like so you can ensure you buy enough materials. Measure the length and width of the area you want to cover. Multiply the length times the width. This will give you the square footage of your future patio. If the shape of your patio is not square but you will use square pavers, you will need to estimate the square footage. Another option is to use pavers that are designed to be laid in round shapes. These type of pavers will require you to take different types of measurements to determine the amount of pavers needed. If you are building stairs on your patio, you may need to subtract the square footage of the bottom stair and purchase some retaining blocks. Pavers come in a multitude of shapes, sizes, colors, and prices, so you have decisions to make. When determining which pavers to use, compare how much it will cost you to cover the whole patio area. Some pavers are sold by the square foot and some are sold as individual blocks. Small pavers may be cheaper individually but they could end up costing you more in the end to cover your square footage. They are also much more labor-intensive, which can cost you in terms of time and effort. To figure out how many pavers you will need, multiply the square footage of your patio by the stones per square foot of the pavers you are considering (a number that should be on price labels or listed on product specs), this will give you the number of stones needed. For example, if you are making a 100 square foot patio and the pavers you are using are listed as 4 square feet per piece, multiply 100 by 4 and the total number of pieces you will need is 400. Once you have that number, you can figure out how much specific pavers will cost you overall by multiplying the number of pavers needed by the price per paver. Remember, pavers can be arranged in a multitude of different patterns; a sales associate at your home improvement store should be able to make suggestions if you can't decide. Make sure you discuss delivery options with the sales associate. A large number of pavers will weigh quite a lot, and you will likely need them to deliver a pallet to your home. You will need more than pavers to install a patio. The patio should include a layer of gravel and a layer of sand below the pavers, as well as a barrier to keep the pavers in place. All of these supplies should be purchased before you start your project. To determine the amount of gravel and sand you will need to buy, determine the volume of the space you are filling or the cubic feet and cubic yards. The gravel should be at least 4 inches deep, but this will be compacted, so you will want to add another 1.5 inches to your calculation. The sand should be over 1 inch (2.5cm) thick, so these measurements should be multiplied by the square footage of the patio. This will give you the cubic feet you need. You can also use an online calculator, such as the one here: http://www.calculatorsoup.com/calculators/construction/ If all else fails, consult a sales associate at your home improvement store. They should be able to help you figure out how much sand and gravel you will need for the square footage of your patio. Talk to them about your options for buying supplies like sand in bulk to save money. Make sure you buy polymeric sand to fill in the spaces or joints between the pavers. Regular washed sand will not bind together well and your pavers will become loose. Decide if you want to lay a fabric weed barrier between the gravel and the pavers. The sand and gravel is usually enough to keep weeds from growing between your pavers, but this added layer provides additional blockage. Make sure the barrier is porous so that you still get proper drainage through the gravel. When you purchase pavers makes sure you buy at least 10 percent more than you plan to use. Paver blocks can break or you may need to cut some to fit around obstacles. You may also need to rent a gas powered plate compactor as well as a paver wet saw with diamond blade and stand if you need to trim or shape the pavers.

summary: Measure the area where you want your patio. Decide on the pavers to use for your patio. Purchase pavers and other supplies.

Summarize the following:
Combine the chopped onions, olive oil, garlic, cumin, oregano, chiles, cider vinegar, and salt in a blender or food processor. Blend the ingredients together at medium to high speed until a thick puree forms. Do not drain the adobo sauce from the chipotle chiles before adding them. You should pour the sauce into the blender along with the chiles. Spread the sauce into the bottom of your slow cooker. Place the beef on top of it, and pour the beef broth over the meat. Place the bay leaf on top. Coat the beef in the sauce by turning it a few times, dipping all sides in the sauce at least once in the process. Use a 5-qt to 7-qt (5-L to 7-L) slow cooker for best results. Cut the beef into several chunks, if necessary, to fit it into the slow cooker. If you want it done sooner, set the slow cooker to high and cook the beef for 6 hours. Resist the temptation to open the lid and peek at your meal as it cooks. Doing so releases the trapped steam, and that steam is partially responsible for cooking the meat. As a result, the overall cooking time can increase 15 to 30 minutes every time you open the slow cooker. Remove the beef from the slow cooker and place it on a cutting board or rimmed baking sheet. Use two forks to shred the beef into pieces, working from the outside in. While shredding the beef, you should also discard any fat. A rimmed baking sheet or cutting board works best since some of the juices inside the beef can run as you work with it. Without a rimmed surface, these juices can create a big mess. Transfer the shredded beef to a large bowl. Ladle a little of the cooking liquid into the bowl, mixing after each addition. Add enough sauce to keep the beef thoroughly moist, but do not add so much that the beef drown in it or becomes soupy. If you have some cooking liquid left behind after you coat the beef, you can fill a spare ice cube tray with it and freeze the liquid for later use. These cubes of barbacoa sauce can be used to flavor stocks, soups, gravies, and other dishes later on. If you are not ready to serve the barbacoa yet, return it to the slow cooker and switch the appliance to its "warm" setting. You can keep it warm using this method for another 2 to 4 hours. After that point, you should consider transferring any uneaten beef to airtight containers and storing it in the refrigerator. Reheat it in the microwave after refrigerator storage. The beef barbacoa is ready to eat. Serve it to your family or guests while still warm, and offer it with an accompaniment of tortillas, onion, cilantro, and salsa.
summary: Puree the sauce ingredients. Layer the sauce, beef, and broth in the slow cooker. Cover and cook on low for 8 to 10 hours. Shred the beef. Mix the shredded beef with the barbacoa sauce. Keep it warm in the slow cooker. Serve.
