+#### 1. you should have cloned your repo as SSH :
+ `https >> git clone https://github.com/USERNAME/REPOSITORY.git`             
+ `SSH   >> git clone git@github.com:USERNAME/REPOSITORY.git`
+#
+#### 2. making SSH key pair:
+    ssh-keygen
+- skip all questions
+- now you have ssh key pair in ~/.ssh/
+- ( id_rsa ) > (private key)
+- ( id_rsa.pub ) > (public key)
+- note: now you can send your public key (id_rsa.pub) anywhere you wanna have ssh access.
+#
+#### 3. adding public key to your github account:
+**go to:**
+1. setting
+2. SSH and GPG keys
+3. new ssh key
+4. enter a title
+5. copy the content of your id-rsa.pub into the Key field
+6. submit add key
+7. Done
+#
+###### now in git push , you do not need to enter username and password.
+###### its going to be done by SSH key pair, you have private key and your github account has public key.
+#### DONE
