+### 🔐 Option 1: **Access Token (Recommended & Easiest)**
+
+### 🔑 Option 2: **SSH Key (Advanced, one-time setup)**
+
+---
+
+## ✅ Let's go with **Option 1: Use a Hugging Face Access Token**
+
+### 🔧 Step-by-Step:
+
+#### ✅ 1. **Generate an Access Token**
+
+* Go to: [https://huggingface.co/settings/tokens](https://huggingface.co/settings/tokens)
+* Click **“New token”**
+
+  * Name: `Git Push`
+  * Role: `Write` or `Admin`
+* Copy the token (keep it safe like a password!)
+
+---
+
+#### ✅ 2. **Push using the Access Token**
+
+Use this format when pushing:
+
+```bash
+git push https://<token>@huggingface.co/spaces/selvaneyas/Edu-MentorAI
+```
+
+🔁 For example:
+
+```bash
+git push https://hf_A1b2C3d4e5f6G7h8I9J0@huggingface.co/spaces/selvaneyas/Edu-MentorAI
+```
+
+> Replace `hf_A1b2C3...` with your **real token**
+
+---
+
+### ✅ Or set it once using `git remote set-url`:
+
+```bash
+git remote set-url hf https://<your-token>@huggingface.co/spaces/selvaneyas/Edu-MentorAI
+```
+
+Then push as usual:
+
+```bash
+git push hf main
+```
+
+---
+
+## 🔐 Option 2 (Advanced): SSH Setup (Optional)
+
+If you prefer SSH instead of tokens, I can guide you on setting up an SSH key and linking it with Hugging Face.
