Article: Do not bleach your hair if it has been relaxed, chemically straightened, or texturized, as this can damage your hair beyond repair. You can work on freshly-washed hair, but make sure that it is completely dry before you begin. Bleaching is easier on shorter hair than longer hair. If you have never done this before, or feel uncomfortable, consider going to a stylist. Divide your hair into at least 8 sections first, then twist each section into a 2-strand rope braid. This will help stretch your hair out and make it easier to work with. The exact number of twists does not really matter. If you have short hair (i.e. TWA or Teeny Weeny Afro), you don’t need to twist it. Just comb it out to ensure that there are no knots or tangles. Be sure to apply it all along your hairline, including the sides and back of your head. You could also apply some to the tips and edges of your ears as well. This will help protect your skin against the bleach. The type of oil that you use does not matter. It can be olive oil, coconut oil, etc. A button-up shirt would work the best because it is easier to get in and out of. If you don't have any shirts to spare, then drape an old towel or plastic dyeing cape over your shoulders instead. If you're worried about damaging your floor and/or counter, cover it with paper or plastic bags. Newspaper or plastic tablecloths will also work. You can buy these separately or as a kit, but make sure that they both come from the same brand. Since each brand is a little different read the instructions on the package to find out exactly what proportions you should use. In most cases, however, expect to use a 1-to-1 ratio of powder to developer.  If possible, choose a powder and developer that are safe to use on your scalp. Measure out enough developer to saturate your hair, like a hair mask. About 4 ounces (120 mL) of developer should be enough for shoulder-length hair. 20 volume developer is the safest and least damaging, but you can try a 30 volume developer instead if you feel confident bleaching your hair. Just be aware that a 30 volume developer will lighten your hair 3 levels and do so much more quickly than a 20 volume developer, which will lighten your hair 2 levels at a slower rate. You can do this with the handle of your tinting brush or with a plastic (not metal) spoon. Be sure to scrape the bottom and sides of the bowl often so that everything mixes evenly. The color should be consistent with no streaks or swirls. When mixed, bleach will range from white to blue to purple, depending on the brand you got.
Question: What is a summary of what this article is about?
Start with dry, unprocessed hair. Twist your hair into multiple rope braids if it's long. Apply oil or petroleum jelly to your hairline. Pull on a pair of plastic gloves and a shirt that you don't care about. Measure your lightening powder and developer into a non-metal bowl. Mix the powder and developer until they have a batter-like consistency.

Problem: Article: Now you can start inserting pictures. Use File → Open to open each picture you’d like to insert. Each one will open in a new window. Transfer them onto the collage in one of the following ways:  Drag the file directly into the collage document, without opening it, or open it and drag the image into the collage. Name the new Layer something descriptive. (To select more than one file at a time, hold down Ctrl.)  Or open the file with File → Place Embedded (or just Place in older versions.)  Or open the image and use copy paste functions to transfer it to the collage. See the information on adding a background above for more information. If you only want part of the picture, select the rectangular marquee tool at the top of the Tools panel. Drag it over part of the image, then copy and paste it as described above. If you want to cut out shapes more complicated than a rectangle, use the Lasso tool in the Tools window. Draw carefully around the area you want to remove, then press Delete to get rid of it. For a quicker, less precise job, select the Quick Selection tool by pressing W.  Use Ctrl+Alt+Z to undo a mistake. Press the magnifying glass to zoom in before selecting small or detailed areas. Select an image in your “photoshop collage” document by clicking its name in the Layers panel. Press Ctrl+T to enter Transform mode. You can now edit the image as follows:  To resize the image, drag any corner. Hold down Shift while doing this to make sure the image doesn't distort. To rotate the image, move your cursor farther out from a corner until you see two arrows. Click and hold, then drag the image. To move the image, click and hold anywhere inside the image and drag. When you're done, press Enter or click the check mark near the top right corner. The layer at the top of the Layers panel will be on top of all other images. Click and drag layer names up and down the list to change which picture is on top of another. Make sure your “background” layer is always at the bottom. Anything below it will not be visible. Save your changes using File → Save, then print using File → Print. Or if you think the collage needs some words or styling, read the section below and print once you're done. Use File → Save As instead to change file formats. Choose PDF if you want your collage professionally printed or framed. Choose JPEG to make an image that other photo viewing software can open.
Summary: Insert pictures. Cut out pieces. Edit pictures. Overlap pictures. Save the file and print it.

These are the slots that you can install expansion cards into. PCI slots are typically white, and you may have 1-5 of them. The slots line up with the removable panels on the back of the case. If you're having difficulty identifying the PCI slots, check your motherboard's documentation. You can look this up online if you have the motherboard's model number. If you are replacing an old card, remove the old card first. Having two cards installed will lead to hardware conflicts. Remove the screw securing the card to your case and pull the card directly out of the slot.  You may need to disconnect the sound card from your CD/DVD drive. Make sure that any speakers connected to the old sound card are disconnected before you remove the old card. Remove the corresponding dust guard panel from the back if you are installing the new card. Make sure that the notches in the slot line up with the card, and press the card straight down firmly. Don't force the card into the slot, and ensure that the ports on the back line up with the with the bay opening. Screw a single screw into the metal tab that secures the card to the computer chassis. Don't overtighten, but ensure the card is snugly fastened to the case. Some older sound cards may connect to the CD/DVD drive with a small cable. This is optional on virtually all newer computers, as this connection is now handled by the hardware. Return the side panel to the computer and secure it. Place the computer back at your desk and plug the cables back in.
