+What's up folks! Markiplier here, I will show you how to work with SSH for different systems. I don't have any expirience with Apple software but it should handle the same as Linux I will mention if Windows needs special attention.

 SSH stands for **S**ecure **Sh**ell. It's used most commonly for connecting to servers/computers. It was a replacement for Telnet, which is plaintext, while SSH uses stronk encryption. The most common SSH is OpenBSD's OpenSSH, but there are alternatives like Dropbear.

 There flags that you should know
-  * ''-p'' for port
-  * ''-i <your private key'' include key
-  * ''-v'' verbose, if you need more info on what is happening during connection and breaking it
-  * ''-R <server port>:localhost:<client port>'' port forwarding from __server__ to client
-  * ''-L <client port>:localhost:<server port>'' port forwarding from client to __server__
-  * ''-N'' do not execute any commands, useful for port forwarding
-  * ''-f'' run ssh in background after auth, also useful for port forwarding
+^ flag  ^ what is it for ^

-<file - config>
+=== How to simplify connections ===
-Host <yourname>
+You can create ''config'' file in your .ssh folder, it's located in your /home/<user> directory, or /root or in C:\Users\<user> in case of Windows
+<code - config>
+Host <your chosen name>
   Hostname <your IP/domain>
   User <your username>
   IdentityFile <path to private SSH key>
   Port <port opened for SSH>
-</file>

+You have way more settings to work with so look them up and have fun! Flags mentioned above can be also set in ''~/.ssh/config'' //(with appropriate keywords)//
+How does my machine become a server?
+In case of Linux and Unix like systems, you should start sshd daemon, like
+''# systemctl enable --now sshd''
+It's best to edit ''/etc/ssh/sshd_config'' as sudo/root and change the settings you want.
+In general it's best to disable passwords and root login. Just uncomment the line by deleting "#" and write yes/no in appropriate place
