+ `AFNetworkActivityIndicatorManager` manages the state of the network activity indicator in the status bar. When enabled, it will listen for notifications indicating that a session task has started or finished, and start or stop animating the indicator accordingly. The number of active requests is incremented and decremented much like a stack or a semaphore, and the activity indicator will animate so long as that number is greater than zero.
+
+ You should enable the shared instance of `AFNetworkActivityIndicatorManager` when your application finishes launching. In `AppDelegate application:didFinishLaunchingWithOptions:` you can do so with the following code:
+
+    [[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
+
+ By setting `enabled` to `YES` for `sharedManager`, the network activity indicator will show and hide automatically as requests start and finish. You should not ever need to call `incrementActivityCount` or `decrementActivityCount` yourself.
+
+ See the Apple Human Interface Guidelines section about the Network Activity Indicator for more information:

+
+/** To perform queries and updates on multiple threads, you'll want to use `FMDatabaseQueue`.
+
+ Using a single instance of `<FMDatabase>` from multiple threads at once is a bad idea.  It has always been OK to make a `<FMDatabase>` object *per thread*.  Just don't share a single instance across threads, and definitely not across multiple threads at the same time.
+
+ Instead, use `FMDatabaseQueue`. Here's how to use it:
+
+ First, make your queue.
+
+    FMDatabaseQueue *queue = [FMDatabaseQueue databaseQueueWithPath:aPath];
+
+ Then use it like so:
+
+    [queue inDatabase:^(FMDatabase *db) {
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:1]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:2]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:3]];
+
+        FMResultSet *rs = [db executeQuery:@"select * from foo"];
+        while ([rs next]) {
+            //…
+        }
+    }];
+
+ An easy way to wrap things up in a transaction can be done like this:
+
+    [queue inTransaction:^(FMDatabase *db, BOOL *rollback) {
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:1]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:2]];
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:3]];
+
+        if (whoopsSomethingWrongHappened) {
+            *rollback = YES;
+            return;
+        }
+        // etc…
+        [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:4]];
+    }];
+
+ `FMDatabaseQueue` will run the blocks on a serialized queue (hence the name of the class).  So if you call `FMDatabaseQueue`'s methods from multiple threads at the same time, they will be executed in the order they are received.  This way queries and updates won't step on each other's toes, and every one is happy.
+
+ ### See also
+
+ - `<FMDatabase>`
+
+ @warning Do not instantiate a single `<FMDatabase>` object and use it across multiple threads. Use `FMDatabaseQueue` instead.
+ 
+ @warning The calls to `FMDatabaseQueue`'s methods are blocking.  So even though you are passing along blocks, they will **not** be run on another thread.
