+## Manual Installation Guide
+
+### Build SDWebImage as Framework or Static Library
+
+For most user, to use SDWebImage, just need to build SDWebImage source code into a framework or static library.
+
+For framework, you can choose to use Dynamic Framework (Link during runtime) or Static Framework (Link to the main executable file like Static Library).
+
+It's strongly recommended to use Framework instead of Static Library. Framework can bundle resource and header files together, and have module map for clang module. Which make it easy to use.
+
+And more importantly, Swift can only import the Objective-C code by using modular framework, or using the Bridging Header. (Bridging header contains its own disadvantage but this is beyond the topic).
+
+#### Clone the repository:
 
-In order to gain access to all the files from the repository, you should clone it.
 ```
-git clone --recursive https://github.com/SDWebImage/SDWebImage.git
+git clone https://github.com/SDWebImage/SDWebImage.git
 ```
 
-... TO BE CHECKED AND DESCRIBED IN DETAIL
+Then open the `SDWebImage.xcodeproj`.
+
+#### Select the Build Scheme you need
+
+- `SDWebImage` for dynamic framework. You can also change the `Mach-O Type` to `Static Library` to build static framework in `Build Settings`.
+- `SDWebImage Static` for static library.
+- `SDWebImageMapKit` for MapKit sub component only.
 
-### Add dependencies
+#### Select Build Platform you need
 
-- 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:
+- `My Mac` for macOS platform.
+- `Generic iOS Device` for iOS platform.
+- `Generic tvOS Device` for tvOS platform.
+- `Generic watchOS Device` for watchOS platform.
+- Simulator Device for Simulator platform.
 
-### Add Linker Flag
+#### Prepare for archive
 
-Open the "Build Settings" tab, in the "Linking" section, locate the "Other Linker Flags" setting and add the "-ObjC" flag:
+If you want to build framework for Real Device, don't try to click `Build` (Command + R). Because by default it will use the `DEBUG` configuration, which is not suitable for production. It's mostly used for Simulator.
 
-![Other Linker Flags](https://user-images.githubusercontent.com/6919743/30030628-be2daf6a-91c0-11e7-8b5c-e0ac92d16b80.png)
+Instead, you can use `Archive`. But before we click the button, you need some prepare in the `Build Settings`.
+
+Change the `Skip Install` to `NO`. Or the archived product will not contains any framework.
+
+You can do this by modify the xcconfig file `Module-Shared.xcconfig`. Or you can change it using Xcode GUI.
 
-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
+SKIP_INSTALL = NO
 ```
 
-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:
+#### Build the Framework or Static Library
+
+Now, you can click the `Archive` button (`Product -> Archive`). After the build success. Xcode will pop-up the Organizer window.
+
+Click `Distribute Content`. Then ensure the `Built Products` is selected. Click `Next` and select a build folder your want to export. Click `Export`.
+
+You can find a `SDWebImage.framework`, or `libSDWebImage.a` and the Headers Files inside the build folder.

+
+##### Note for Universal (Fat) Framework
+
+If you need to build Universal Framework (for Simulator and Real Device). You need some command line to combine the framework.
+
+For example, if you already built two frameworks, `iOS/SDWebImage.framework` for iOS Real Device, `Simulator/SDWebImage.framework` for Simulator.
+
 ```
--force_load $(TARGET_BUILD_DIR)/libPods.a
+mkdir Universal/
+cp -R iOS/SDWebImage.framework Universal/SDWebImage.framework
+lipo -create Simulator/SDWebImage.framework/SDWebImage iOS/SDWebImage.framework/SDWebImage -output Universal/SDWebImage.framework/SDWebImage
 ```
-and this:
+
+For Static Library, just do the same thing.
+
 ```
-$(inherited)
+mkdir Universal/
+lipo -create Simulator/libSDWebImage.a iOS/libSDWebImage.a -output Universal/libSDWebImage.a
 ```
+
+#### Link the Framework or Static Library to your project
+
+Under your Project folder. You can create a `Vendor` folder to place the Framework or Static Library.
+
+##### For Framework (Dynamic or Static)
+
+For Framework (Dynamic or Static), the Headers are inside the framework. Just copy the `SDWebImage.framework` into the `Vendor` folder.
+
+If your project is App project and using Dynamic Framework. You need to click `Embedded Binaries`. Select `Add Other...` and select the `SDWebImage.framework`. Xcode automatically add it into the `Linked Frameworks and Libraries` as well.
+
+If not (Framework project or using Static Framework). Click
+click `Linked Frameworks and Libraries`. Select `Add Other...` and select the `SDWebImage.framework`.
+
+Then all things done if you use Framework.

+
+##### For Static Library
+
+For Static Library, you need copy both the `libSDWebImage.a` as well as the Headers into the `Vendor` folder.
+
+![](https://user-images.githubusercontent.com/6919743/55804133-4e218480-5b0e-11e9-86ac-f17aabf6e0c5.png)
+
+Open your application Xcode Project, click `Linked Frameworks and Libraries`. Select `Add Other...` and select the `libSDWebImage.a`.
+
+After link, you need to specify the Header Search Path for headers. Check Build Settings's `Header Search Path`, add the Header Search Path, where there must be a `SDWebImage` parent directory of `SDWebImage.h` this umbrella header file.
+
+The example above can using the following path.
+
+```
+$(SRCROOT)/Vendor
+```
+
+Then all things done if you use Static Library.

+
+### Using SDWebImage as Sub Xcode Project
+
+You can also embed SDWebImage as a Sub Xcode Project using in your Xcode Project/Workspace. This can be used for some specify environment which does not support external dependency manager.
+
+#### Clone the repository as submodule
+
+To embed the Sub Xcode Project, you can simply add SDWebImage entire project using Git Submodule. 
+
+```
+cd Vendor/
+git submodule add https://github.com/SDWebImage/SDWebImage.git
+```
+
+Note: If your project don't using Git Submodule, just copy the entire repo of SDWebImage to that Vendor folder, and you can add to your own Version Control tools.
+
+However, using Git Submodule can make it easy to upgrade framework version and reduce Git repo size.
+
+#### Add `SDWebImage.xcodeproj` into your Workspace/Project
+
+Just drag the `SDWebImage.xcodeproj` you cloned, into your Xcode Workspace/Project 's Project Navigator.
+
+For Xcode Workspace, you can put it the same level of your App Project.
+
+For Xcode Project, you can put it inside your App Project.

+
+#### Link to your App/Framework Target
+
+To use SDWebImage, you should link the `SDWebImage` target.
+
+Go to your App/Framework target's `General` page. Then click `Lined Frameworks and Libraries`, and add the `SDWebImage.framework` or `libSDWebImage.a` (Depends on your use case).
+
+Then all things done.
