 # Generating a key
 After installing ssh, we recommend generating an ECDSA (elliptic crypto key)
+	```
 	ssh-keygen -t ECDSA
+	```
 This will ask for a password to encrypt the private key.
 **It is very very important that you save this password somewhere safe but easy to retrieve.  If you lose it, you will have to generate a new key pair**
 
 	
 This will put the public and private key in your `.ssh` folder
-     id_ed25519      # your private key, password protected
-	 id_ed25519.pub  # your public key
+- `id_ed25519`      # your private key, password protected
+- `id_ed25519.pub`  # your public key
