+#### How to evaluate AP of YOLOv4 on the MS COCO evaluation server
+
+1. Download and unzip test-dev2017 dataset from MS COCO server: http://images.cocodataset.org/zips/test2017.zip
+2. Download list of images for Detection taks and replace the paths with yours: https://raw.githubusercontent.com/AlexeyAB/darknet/master/scripts/testdev2017.txt
+3. Download `yolov4.weights` file: https://drive.google.com/open?id=1cewMfusmPjYWbrnuJRuKhPMwRe_b9PaT
+4. Content of the file `cfg/coco.data` should be
+```
+classes= 80
+train  = <replace with your path>/trainvalno5k.txt
+valid = <replace with your path>/testdev2017.txt
+names = data/coco.names
+backup = backup
+eval=coco
+```
+5. Create `/results/` folder near with `./darknet` executable file
+6. Run validation: `./darknet detector valid cfg/coco.data cfg/yolov4.cfg yolov4.weights`
+7. Rename the file  `/results/coco_results.json` to `detections_test-dev2017_yolov4_results.json` and compress it to `detections_test-dev2017_yolov4_results.zip`
+8. Submit file `detections_test-dev2017_yolov4_results.zip` to the MS COCO evaluation server for the `test-dev2019 (bbox)`
+
+#### How to evaluate FPS of YOLOv4 on GPU
+
+1. Compile Darknet with `GPU=1 CUDNN=1 CUDNN_HALF=1 OPENCV=1` in the `Makefile` (or use the same settings with Cmake)
+2. Download `yolov4.weights` file: https://drive.google.com/open?id=1cewMfusmPjYWbrnuJRuKhPMwRe_b9PaT
+3. Get any .avi/.mp4 video file (preferably not more than 1920x1080 to avoid bottlenecks in CPU performance)
+4. Run one of two commands and look at the AVG FPS:
+* include video_capturing + NMS + drawing_bboxes: 
+    `./darknet detector demo cfg/coco.data cfg/yolov4.cfg yolov4.weights test.mp4 -dont_show -ext_output`
+* exclude video_capturing + NMS + drawing_bboxes: 
+    `./darknet detector demo cfg/coco.data cfg/yolov4.cfg yolov4.weights test.mp4 -benchmark`
+
 #### Pre-trained models
 
 There are weights-file for different cfg-files (trained for MS COCO dataset):
