 APAddressBook
-=============
+============
+
+#### About
+APAddressBook is a wrapper on [AddressBook.framework](https://developer.apple.com/library/ios/documentation/AddressBook/Reference/AddressBook_iPhoneOS_Framework/_index.html)
+
+---
+
+#### Features
+* Load contacts from iOS address book asynchronously
+* Decide what contact data fields you need to load (for example, only first name and phone number)
+* Filter contacts to get only necessary records (for example, you need only contacts with email)
+* Sort contacts with array of any [NSSortDescriptor](https://developer.apple.com/library/mac/documentation/cocoa/reference/foundation/classes/NSSortDescriptor_Class/Reference/Reference.html)
+
+#### Installation
+Add `APAddressBook` pod to Podfile
+
+---
+
+#### Using
+
+###### Load contacts
+```objective-c
+APAddressBook *addressBook = [[APAddressBook alloc] init];
+// don't forget to show some activity
+[addressBook loadContacts:^(NSArray *contacts, NSError *error)
+{
+    // hide activity
+    if (!error)
+    {
+        // do something with contacts array
+    }
+    else
+    {
+        // show error
+    }
+}];
+```
+
+---
+
+###### Select contact fields bit-mask
+Available fields:
+* APContactFieldFirstName - *contact first name*
+* APContactFieldLastName - *contact last name*
+* APContactFieldCompany - *contact company (organisation)*
+* APContactFieldPhones - *contact phones array*
+* APContactFieldEmails - *contact emails array*
+* APContactFieldPhoto - *contact photo*
+* APContactFieldDefault - *contact first name, last name and phones array*
+* APContactFieldAll - *all contact fields described above*
+
+Example of loading contact with first name and photo:
+```objective-c
+APAddressBook *addressBook = [[APAddressBook alloc] init];
+addressBook.fieldsMask = APContactFieldFirstName | APContactFieldPhoto;
+```
+
+---
+
+###### Filter contacts
+The most common use of this option is to filter contacts without phone number
+Example:
+```objective-c
+addressBook.filterBlock = ^BOOL(APContact *contact)
+{
+    return contact.phones.count > 0;
+};
+```
+
+---
+
+###### Sort contacts
+APAddressBook returns unsorted contacts. So, most of users would like to sort contacts by first name and last name.
+```objective-c
+addressBook.sortDescriptors = @[
+    [NSSortDescriptor sortDescriptorWithKey:@"firstName" ascending:YES],
+    [NSSortDescriptor sortDescriptorWithKey:@"lastName" ascending:YES]
+];
+```
+
+###### Check address book access
+```objective-c
+switch([APAddressBook access])
+{
+    case APAddressBookAccessUnknown:
+        // Application didn't request address book access yet
+        break;
+
+    case APAddressBookAccessGranted:
+        // Access granted
+        break;
+
+    case APAddressBookAccessDenied:
+        // Access denied or restricted by privacy settings
+        break;
+}
+```
