+# SSH configuration for git
 
+Add this in your `~/.ssh/config` file:
+```
+Host git.home
+  HostName 192.168.3.29
+  Port 222
+  User git
+  IdentityFile ~/.ssh/id_ed25519
+  IdentitiesOnly yes
+```
+
+## 🔐 Notes
+
+- This example uses an **ED25519 key**. If you're using an **RSA key** (`id_rsa`), change the `IdentityFile` line to:
+```
+IdentityFile ~/.ssh/id_rsa
+```
+
+- To generate a new ED25519 key:
+```
+ssh-keygen -t ed25519 -C "your_email@example.com"
+```
+
+- Make sure your public key is added to your Gitea profile.
