 **Before reporting an issue:**
 - Check if your system matches all the minimum requirements listed in the [Quickstart Guide](https://rpcs3.net/quickstart);
-- Check if the issue is meaningful for the team (e.g. The Last of Us doesn't work is obvious and therefore useless);
-- Search older issues/forum threads to see if your issue was already submitted.
-- Use understandable English. It doesn't need to be perfect, but clear enough to understand your message.
-- While reporting issues, don't forget to include details about your system (OS, CPU, GPU, etc.), as well as the RPCS3.log file.

 Submitting your test results for Commercial Games must be done on our forums. Please read the [Game Compatibility](https://github.com/RPCS3/rpcs3/wiki/Game-Compatibility) wiki page before doing so.

+## Please do not ask for help or report compatibility regressions here, use [RPCS3 Discord server](https://discord.me/RPCS3) or [forums](https://forums.rpcs3.net/) instead.
+
+## Quick summary
+Please briefly describe what has stopped working correctly.
+
+## Details
+Please describe the regression as accurately as possible.
+
+#### 0. Make sure you're running with settings as close to default as possible
+* **Do NOT enable any emulator game patches when reporting issues**
+* Only change settings that are required for the game to work
+
+#### 1. Please provide _exact_ build (or commit) information that introduced the regression you're reporting.
+* Please see [How to find the build that caused a regression](https://wiki.rpcs3.net/index.php?title=Help:Using_different_versions_of_RPCS3#How_to_find_the_build_that_caused_a_regression.3F) in our wiki.
+* You can find [History of RPCS3 builds](https://rpcs3.net/compatibility?b) here.
+
+#### 2. Please attach TWO logs:
+* One for the build with regression.
+* One for the build that works as expected.
+
+##### How to obtain RPCS3's log:
+* Run the game until you find the regression.
+* Completely close RPCS3, or move to the next step in case it has crashed.
+* Locate RPCS3's log file:
+	+ ```RPCS3.log``` (It can show up as just RPCS3 and have a notepad icon)
+	or
+	+ ```RPCS3.log.gz``` (It can show up as RPCS3.log and have a zip or rar icon)
+![image](https://user-images.githubusercontent.com/44116740/84433247-aa15fa80-ac36-11ea-913e-6fe25a1d040e.png)
+	On Linux it will be in ```~/.cache/rpcs3/```.
+	On Windows it will be near the executable.
+* Attach the log:
+	+ Drag and drop your log file into the issue.
+	+ Or upload it to the cloud, such as Dropbox, Mega etc.
+
+#### 3. If you describe graphical regression, please provide an RSX capture and a RenderDoc capture that demonstrate it.
+* To create an RSX capture, use _Create_ _RSX_ _Capture_ under _Utilities_.
+Captures will be stored in RPCS3 folder → captures.
+	+ Compress your capture with 7z, Rar etc.
+	And drag and drop it into the issue.
+	+ Or upload it to the cloud, such as Dropbox, Mega etc.
+* To create a RenderDoc capture, please refer to [RenderDoc's documentation](https://renderdoc.org/docs/how/how_capture_frame.html).
+
+#### 4. Please attach screenshots of your problem.
+* Enable performance overlay with at least medium level of detail.
+You can find it in _Emulator_ tab in _Settings_.
+
+#### 5. Please provide comparison with real PS3.
+
+#### 6. Please provide your system configuration:
+* OS
+* CPU
+* GPU
+* Driver version
+* etc.
+
+#### Please include.

+level - compression level: 0 <= level <= 9, the default value for "level" is 5.
+
+dictSize - The dictionary size in bytes. The maximum value is

+          1 GB = (1 << 30) bytes for 64-bit version
+     The default value is 16 MB = (1 << 24) bytes, for level = 5.
+     It's recommended to use the dictionary that is larger than 4 KB and
+     that can be calculated as (1 << N) or (3 << N) sizes.
+     For better compression ratio dictSize must be >= inSize.

+    SZ_FILTER_AUTO - it tries both alternatives to select best.

+              3 passes when FILTER_YES provides better compression.

+ 
+  The default value for "level" is 5.

+
+dictSize - The dictionary size in bytes. The maximum value is

+          1 GB = (1 << 30) bytes for 64-bit version
+     The default value is 16 MB = (1 << 24) bytes.
+     It's recommended to use the dictionary that is larger than 4 KB and
+     that can be calculated as (1 << N) or (3 << N) sizes.
+
+lc - The number of literal context bits (high bits of previous literal).
+     It can be in the range from 0 to 8. The default value is 3.
+     Sometimes lc=4 gives the gain for big files.
+
+lp - The number of literal pos bits (low bits of current position for literals).
+     It can be in the range from 0 to 4. The default value is 0.
+     The lp switch is intended for periodical data when the period is equal to 2^lp.
+     For example, for 32-bit (4 bytes) periodical data you can use lp=2. Often it's
+     better to set lc=0, if you change lp switch.
+
+pb - The number of pos bits (low bits of current position).
+     It can be in the range from 0 to 4. The default value is 2.
+     The pb switch is intended for periodical data when the period is equal 2^pb.
+
+fb - Word size (the number of fast bytes).
+     It can be in the range from 5 to 273. The default value is 32.
+     Usually, a big number gives a little bit better compression ratio and
+     slower compression process.
+
+numThreads - The number of thereads. 1 or 2. The default value is 2.
+     Fast mode (algo = 0) can use only 1 thread.
