+
+## 🕵️‍♂️ Check GPUs
+
+- `hashcat -I` 🖥️  
+  **Note**: Check available GPUs on the system.
+
+---
+
+## 🗝️ Hash Types
+
+- `hashcat -m 0` 🔐  
+  **Note**: MD5.
+- `hashcat -m 1000` 🔑  
+  **Note**: NTLM.
+- `hashcat -m 2500` 🔓  
+  **Note**: WPA/WPA2.
+- `hashcat -m 22000` 🔓  
+  **Note**: WPA-PMKID-PBKDF2.
+
+---
+
+## ⚔️ Attack Modes
+
+- `hashcat -a 0` 🗡️  
+  **Note**: Straight attack.
+- `hashcat -a 3` 🛡️  
+  **Note**: Brute-force attack.
+
+---
+
+## 🪄 Wordlists
+
+- `hashcat -w 4` 📘  
+  **Note**: Set workload profile.
+
+---
+
+## 🔨 Incremental Mode
+
+- `-increment` ♾️  
+  **Note**: Enable incremental mode.
+- `-increment-min 8`  
+  **Note**: Set minimum password length.
+- `-increment-max 12`  
+  **Note**: Set maximum password length.
+
+---
+
+## 🎯 Custom Charsets
+
+- `?d?l?u` 🎲  
+  **Note**: Digits, lowercase, uppercase letters.
+- `?s` ❇️  
+  **Note**: Special characters.
+- `?a` 🎯  
+  **Note**: All characters (lowercase, uppercase, digits, special).
+
+---
+
+## 💡 Examples
+
+### 🚀 Brute force WPA2 PMKID hash:
+
+```bash
+hashcat -m 22000 -a 3 hash.hc22000 ?d?d?d?d?d?d?d?d
+```
+
+- `m 22000`: WPA-PMKID-PBKDF2 hash.
+- `a 3`: Brute-force attack.
+- `?d?d?d?d?d?d?d?d`: 8-digit brute-force mask.
+
+### ⚡ Incremental attack on WPA2 hash:
+
+```bash
+hashcat -m 22000 hash.hc22000 --increment --increment-min 8 --increment-max 12 ?d?d?d?d?d?d?d?d?d
+```
+
+- `-increment`: Incremental mode.
+- `-increment-min 8`: Min length 8.
+- `-increment-max 12`: Max length 12.
+- `?d?d?d?d?d?d?d?d?d`: 8-12 digit incremental mask.
