+
+Who Uses It
+----------
+
+Find out [who uses SDWebImage](https://github.com/rs/SDWebImage/wiki/Who-Uses-SDWebImage) and add your app to the list.
+
+How To Use
+----------
+
+API documentation is available at [CocoaDocs - SDWebImage](http://cocoadocs.org/docsets/SDWebImage/)
+
+### Using UIImageView+WebCache category with UITableView
+
+Just #import the UIImageView+WebCache.h header, and call the sd_setImageWithURL:placeholderImage:
+method from the tableView:cellForRowAtIndexPath: UITableViewDataSource method. Everything will be
+handled for you, from async downloads to caching management.
+
+```objective-c
+#import <SDWebImage/UIImageView+WebCache.h>
+
+...
+
+- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
+    static NSString *MyIdentifier = @"MyIdentifier";
+
+    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
+    if (cell == nil) {
+        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
+                                       reuseIdentifier:MyIdentifier] autorelease];
+    }
+
+    // Here we use the new provided sd_setImageWithURL: method to load the web image
+    [cell.imageView sd_setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]
+                      placeholderImage:[UIImage imageNamed:@"placeholder.png"]];
+
+    cell.textLabel.text = @"My Text";
+    return cell;
+}
+```
+
+### Using blocks
+
+With blocks, you can be notified about the image download progress and whenever the image retrieval
+has completed with success or not:
+
+```objective-c
+// Here we use the new provided sd_setImageWithURL: method to load the web image
+[cell.imageView sd_setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]
+                      placeholderImage:[UIImage imageNamed:@"placeholder.png"]
+                             completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
+                                ... completion code here ...
+                             }];
+```
+
+Note: neither your success nor failure block will be call if your image request is canceled before completion.
+
+### Using SDWebImageManager
+
+The SDWebImageManager is the class behind the UIImageView+WebCache category. It ties the
+asynchronous downloader with the image cache store. You can use this class directly to benefit
+from web image downloading with caching in another context than a UIView (ie: with Cocoa).
+
+Here is a simple example of how to use SDWebImageManager:
+
+```objective-c
+SDWebImageManager *manager = [SDWebImageManager sharedManager];
+[manager downloadImageWithURL:imageURL
+                      options:0
+                     progress:^(NSInteger receivedSize, NSInteger expectedSize) {
+                         // progression tracking code
+                     }
+                     completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished, NSURL *imageURL) {
+                         if (image) {
+                             // do something with image
+                         }
+                     }];
+```
+
+### Using Asynchronous Image Downloader Independently
+
+It's also possible to use the async image downloader independently:
+
+```objective-c
+SDWebImageDownloader *downloader = [SDWebImageDownloader sharedDownloader];
+[downloader downloadImageWithURL:imageURL
+                         options:0
+                        progress:^(NSInteger receivedSize, NSInteger expectedSize) {
+                            // progression tracking code
+                        }
+                       completed:^(UIImage *image, NSData *data, NSError *error, BOOL finished) {
+                            if (image && finished) {
+                                // do something with image
+                            }
+                        }];
+```
+
+### Using Asynchronous Image Caching Independently
+
+It is also possible to use the async based image cache store independently. SDImageCache
+maintains a memory cache and an optional disk cache. Disk cache write operations are performed
+asynchronous so it doesn't add unnecessary latency to the UI.
+
+The SDImageCache class provides a singleton instance for convenience but you can create your own
+instance if you want to create separated cache namespace.
+
+To lookup the cache, you use the `queryDiskCacheForKey:done:` method. If the method returns nil, it means the cache
+doesn't currently own the image. You are thus responsible for generating and caching it. The cache
+key is an application unique identifier for the image to cache. It is generally the absolute URL of
+the image.
+
+```objective-c
+SDImageCache *imageCache = [[SDImageCache alloc] initWithNamespace:@"myNamespace"];
+[imageCache queryDiskCacheForKey:myCacheKey done:^(UIImage *image) {
+    // image is not nil if image was found
+}];
+```
+
+By default SDImageCache will lookup the disk cache if an image can't be found in the memory cache.
+You can prevent this from happening by calling the alternative method `imageFromMemoryCacheForKey:`.
+
+To store an image into the cache, you use the storeImage:forKey: method:
+
+```objective-c
+[[SDImageCache sharedImageCache] storeImage:myImage forKey:myCacheKey];
+```
+
+By default, the image will be stored in memory cache as well as on disk cache (asynchronously). If
+you want only the memory cache, use the alternative method storeImage:forKey:toDisk: with a negative
+third argument.
+
+### Using cache key filter
+
+Sometime, you may not want to use the image URL as cache key because part of the URL is dynamic
+(i.e.: for access control purpose). SDWebImageManager provides a way to set a cache key filter that
+takes the NSURL as input, and output a cache key NSString.
+
+The following example sets a filter in the application delegate that will remove any query-string from
+the URL before to use it as a cache key:
+
+```objective-c
+- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
+    SDWebImageManager.sharedManager.cacheKeyFilter = ^(NSURL *url) {
+        url = [[NSURL alloc] initWithScheme:url.scheme host:url.host path:url.path];
+        return [url absoluteString];
+    };
+
+    // Your app init code...
+    return YES;
+}
+```
+
+
+Common Problems
+---------------
+
+### Using dynamic image size with UITableViewCell
+
+UITableView determines the size of the image by the first image set for a cell. If your remote images
+don't have the same size as your placeholder image, you may experience strange anamorphic scaling issue.
+The following article gives a way to workaround this issue:
+
+[http://www.wrichards.com/blog/2011/11/sdwebimage-fixed-width-cell-images/](http://www.wrichards.com/blog/2011/11/sdwebimage-fixed-width-cell-images/)
+
+
+### Handle image refresh
+
+SDWebImage does very aggressive caching by default. It ignores all kind of caching control header returned by the HTTP server and cache the returned images with no time restriction. It implies your images URLs are static URLs pointing to images that never change. If the pointed image happen to change, some parts of the URL should change accordingly.
+
+If you don't control the image server you're using, you may not be able to change the URL when its content is updated. This is the case for Facebook avatar URLs for instance. In such case, you may use the `SDWebImageRefreshCached` flag. This will slightly degrade the performance but will respect the HTTP caching control headers:
+
+``` objective-c
+[imageView sd_setImageWithURL:[NSURL URLWithString:@"https://graph.facebook.com/olivier.poitrey/picture"]
+                 placeholderImage:[UIImage imageNamed:@"avatar-placeholder.png"]
+                          options:SDWebImageRefreshCached];
+```
+
+### Add a progress indicator
+
+See this category: https://github.com/JJSaccolo/UIActivityIndicator-for-SDWebImage
+
+Installation
+------------
+
+There are three ways to use SDWebImage in your project:
+- using CocoaPods
+- copying all the files into your project
+- importing the project as a static library
+
+### Installation with CocoaPods
+
+[CocoaPods](http://cocoapods.org/) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries in your projects. See the [Get Started](http://cocoapods.org/#get_started) section for more details.
+
+#### Podfile
+```
+platform :ios, '7.0'
+pod 'SDWebImage', '~>3.8'
+```
+
+If you are using Swift, be sure to add `use_frameworks!` and set your target to iOS 8+:
+```
+platform :ios, '8.0'
+use_frameworks!
+```
+
+#### Subspecs
+
+There are 3 subspecs available now: `Core`, `MapKit` and `WebP` (this means you can install only some of the SDWebImage modules. By default, you get just `Core`, so if you need `WebP`, you need to specify it). 
+
+Podfile example:
+```
+pod 'SDWebImage/WebP'
+```
+
+### Installation with Carthage (iOS 8+)
+
+[Carthage](https://github.com/Carthage/Carthage) is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods.
+
+To install with carthage, follow the instruction on [Carthage](https://github.com/Carthage/Carthage)
+
+#### Cartfile
+```
+github "rs/SDWebImage"
+```
+
+#### Usage
+Swift
+
+If you installed using CocoaPods:
+```
+import SDWebImage
+```
+
+If you installed manually:
+```
+import WebImage
+```
+
+Objective-C
+
+```
+@import WebImage;
+```
+
+### Installation by cloning the repository
+
+In order to gain access to all the files from the repository, you should clone it.
+```
+git clone --recursive https://github.com/rs/SDWebImage.git
+```
+
+### Add the SDWebImage project to your project
+
+- Download and unzip the last version of the framework from the [download page](https://github.com/rs/SDWebImage/releases)
+- Right-click on the project navigator and select "Add Files to "Your Project":
+- In the dialog, select SDWebImage.framework:
+- Check the "Copy items into destination group's folder (if needed)" checkbox
+
+### Add dependencies
+
+- In you application project app’s target settings, find the "Build Phases" section and open the "Link Binary With Libraries" block:
+- Click the "+" button again and select the "ImageIO.framework", this is needed by the progressive download feature:
+
+### Add Linker Flag
+
+Open the "Build Settings" tab, in the "Linking" section, locate the "Other Linker Flags" setting and add the "-ObjC" flag:
+
+![Other Linker Flags](http://dl.dropbox.com/u/123346/SDWebImage/10_other_linker_flags.jpg)
+
+Alternatively, if this causes compilation problems with frameworks that extend optional libraries, such as Parse,  RestKit or opencv2, instead of the -ObjC flag use:
+```
+-force_load SDWebImage.framework/Versions/Current/SDWebImage
+```
+
+If you're using Cocoa Pods and have any frameworks that extend optional libraries, such as Parsen RestKit or opencv2, instead of the -ObjC flag use:
+```
+-force_load $(TARGET_BUILD_DIR)/libPods.a
+```
+and this:
+```
+$(inherited)
+```
+
+### Import headers in your source files
+
+In the source files where you need to use the library, import the header file:
+
+```objective-c

+
+## Usage
+
+``` swift
+import SQLite
+
+let db = try Connection("path/to/db.sqlite3")
+
+let users = Table("users")
+let id = Expression<Int64>("id")
+let name = Expression<String?>("name")
+let email = Expression<String>("email")
+
+try db.run(users.create { t in
+    t.column(id, primaryKey: true)
+    t.column(name)
+    t.column(email, unique: true)
+})
+// CREATE TABLE "users" (
+//     "id" INTEGER PRIMARY KEY NOT NULL,
+//     "name" TEXT,
+//     "email" TEXT NOT NULL UNIQUE
+// )
+
+let insert = users.insert(name <- "Alice", email <- "alice@mac.com")
+let rowid = try db.run(insert)
+// INSERT INTO "users" ("name", "email") VALUES ('Alice', 'alice@mac.com')
+
+for user in try db.prepare(users) {
+    print("id: \(user[id]), name: \(user[name]), email: \(user[email])")
+    // id: 1, name: Optional("Alice"), email: alice@mac.com
+}
+// SELECT * FROM "users"
+
+let alice = users.filter(id == rowid)
+
+try db.run(alice.update(email <- email.replace("mac.com", with: "me.com")))
+// UPDATE "users" SET "email" = replace("email", 'mac.com', 'me.com')
+// WHERE ("id" = 1)
+
+try db.run(alice.delete())
+// DELETE FROM "users" WHERE ("id" = 1)
+
+db.scalar(users.count) // 0
+// SELECT count(*) FROM "users"
+```
+
+SQLite.swift also works as a lightweight, Swift-friendly wrapper over the C
+API.
+
+``` swift
+let stmt = try db.prepare("INSERT INTO users (email) VALUES (?)")
+for email in ["betty@icloud.com", "cathy@icloud.com"] {
+    try stmt.run(email)
+}
+
+db.totalChanges    // 3
+db.changes         // 1
+db.lastInsertRowid // 3
+
+for row in try db.prepare("SELECT id, email FROM users") {
+    print("id: \(row[0]), email: \(row[1])")
+    // id: Optional(2), email: Optional("betty@icloud.com")
+    // id: Optional(3), email: Optional("cathy@icloud.com")
+}
+
+db.scalar("SELECT count(*) FROM users") // 2
+```

+
+## Installation
+
+> _Note:_ SQLite.swift requires Swift 3 (and [Xcode][] 8) or greater. If you absolutely
+> need compatibility with Swift 2.3 you can use the [swift-2.3][] branch or older
+> released versions. New development will happen exclusively on the master/Swift 3 branch.
+>
+> The following instructions apply to targets that support embedded
+> Swift frameworks. To use SQLite.swift in iOS 7 or an OS X command line
+> tool, please read the [Frameworkless Targets][] section of the
+> documentation.
+
+
+### Carthage
+
+[Carthage][] is a simple, decentralized dependency manager for Cocoa. To
+install SQLite.swift with Carthage:
+
+ 1. Make sure Carthage is [installed][Carthage Installation].
+
+ 2. Update your Cartfile to include the following:
+
+    ```
+    github "stephencelis/SQLite.swift" ~> 0.11.0

+    # Using the default Ruby install will require you to use sudo when
+    # installing and updating gems.
+    [sudo] gem install cocoapods
+    ```
+
+ 2. Update your Podfile to include the following:
+
+    ``` ruby
+    use_frameworks!
