 3. Open the binary file and cs2 (doesnt matter which one goes first)
 ❗ Make sure your game is in full screen windowed
 
+## ✔ Manually Update
+
+* To manually update the esp offsets ive included an offsets.json file which will be created one opened.
+
+1. Go to this [unknowncheats thread](https://www.unknowncheats.me/forum/counter-strike-2-a/576077-counter-strike-2-reversal-structs-offsets.html) and find the latest offsets posted by the community
+
+2. You will find somethig like this
+
+```cpp
+#define dwLocalPlayer 0x1715418 // This is hexadecimal
+```
+
+3. You will have to translate it to decimal and put it in the offsets file next to the esp executable like so, you can use [**this website**](https://www.rapidtables.com/convert/number/hex-to-decimal.html)
+
+```json
+{
+    "dwLocalPlayer": 24204312, // To decimal
+    ...
+}	
+```
+
 ## 📘 Developer Instructions
 
 1. Build the program using Visual Studio 2022
