+# Setting everything up
+
+## Fiddler
+
+- Download and install [Fiddler Classic](https://www.telerik.com/fiddler/fiddler-classic)
+- Open Fiddler Classic and go to the `FiddlerScript` tab
+- Paste in this script
+```
+import System;
+import System.Windows.Forms;
+import Fiddler;
+import System.Text.RegularExpressions;
+class Handlers
+{
+    static function OnBeforeRequest(oS: Session) {
+        if(oS.host.EndsWith(".yuanshen.com") || oS.host.EndsWith(".hoyoverse.com") || oS.host.EndsWith(".starrails.com") || oS.host.EndsWith(".bhsr.com") || oS.host.EndsWith(".kurogame.net") || oS.host.EndsWith(".kurogame.com") || oS.host.EndsWith(".zenlesszonezero.com") || oS.host.EndsWith(".g3.proletariat.com") || oS.host.EndsWith("west.honkaiimpact3.com") || oS.host.EndsWith("westglobal01.honkaiimpact3.com") || oS.host.EndsWith(".os.honkaiimpact3.com") || oS.host.EndsWith("overseas01-appsflyer-report.honkaiimpact3.com") || oS.host.EndsWith(".mihoyo.com") || oS.host.EndsWith("global1.bh3.com")) {
+            oS.host = "127.0.0.1";
+        }
+    }
+};
+```
+- Click `Save Script`
+
+You need Fiddler to be enabled at all times while using private server, since it captures outgoing traffic from PGR and connects it to localhost instead of official servers.
+
+## AscNet server
+
+- Download and unpack, then launch AscNet.exe
+- Most errors will show up in it's terminal window if something happens
+
+In some cases you'll need to run a command `dotnet dev-certs https --trust` in Command Prompt to install required certificate to use the server.
+
+## MongoDB
+
+- Download and install community server together with Compass
+- Run Compass and hit `Connect`
+
+You need MongoDB to create the database, which gonna keep your local account together with items, characters, equipment and so on.
+
+In case of seeing ECONNREFUSED when trying to connect to the DB, there's following solutions as for now:
+
+- Check if the server was properly installed in your control panel; if it isn't, then use repair function in downloaded installer package
+- Check the MongoDB service in Task Manager, if it's not working, then simply click it with right mouse button and hit `Start`
+
+## KRSDK
+
+If everything is properly set up, you should see a blue pop-up window after logo and disclaimer screens. Create local account by filling the fields with anything you want.
+
+**Important!**
+Don't forget to disable all other overlay programs like MSI Afterburner, GeForce Now etc., since they can interfere with IMGUI.
+
+At this point everything is left to do is just confirm the prompted in-game update and enter into account.
