+# On your machine (windows / linux) that you want to get access to from
+
+Setup a (temporary) http server on your machine that always responds with your machine's SSH public key.
+
+Replace the 'YOUR-SSH-KEY-GOES-HERE' if using the golang file of this gist.
+
+# On the CoreOS box you want to access
+
+Call these commands below on the CoreOS box by replacing `IP-OF-YOUR-MACHINE` of your machine having the http server.
+
+```
+curl http://[IP-OF-YOUR-MACHINE]:8888 > ~/.ssh/authorized_keys
+chmod 600 ~/.ssh/authorized_keys
+```
+
+Note that I chose port 8888 in the golang file but it could be changed there and then also adapted in the `curl` command from CoreOS.
+
+# SSH into CoreOS
+Now you should be able to connect if you know the ip. Hint: `ip addr show` to show IPs.
