Add doc for Renode usage notes.

Create a document to keep track of and pool Renode examples and usage
notes.

To be included, Renode script setup, adding extensions in C#, and
Robot workflow.

(Also added small typo-fix in RunningOpenTitanVectorSimulation.md)

+# Running Renode
+
+Tips for running Renode
+
+## Automatically Start Renode Script
+
+To streamline firing-up renode, use the `-e` flag to execute onload:
+
+```
+renode "i @sim/config/shodan_hellovector.resc; start"
+```
+
+This will start the renode script (resc) automatically.
+
+Make sure to follow with `"i @path/to/file.resc; start` where the path starts
+after `$ROOTDIR` (don't include the `$ROOTDIR` in the path).
+
+## Using Headless Mode
+
+To utilize without the pop-up renode consoles, utilize two flags:
+
+1. `--disable-xwt` -- to prevent the windows from opening
+2. `--port 1234` -- or port of choice for prompt access
+
+This can be combined with the `-e` flag:
+```
+renode --disable-xwt --port 1234 -e "i @sim/config/shodan_hellovector.resc; start"
+```
+
+In a separate terminal window (or tmux pane), start a telnet at that port for
+prompt access:
+```
+telnet 127.0.0.1 1234
+```
+
+Using this should create the following prompt:
+```
+$ telnet 127.0.0.1 1234
+Trying 127.0.0.1...
+Connected to 127.0.0.1.
+Escape character is '^]'.
+Renode, version 1.10.1.31213 (773406ba-202011051557)
+
+(monitor) i @sim/config/shodan_hellovector.resc
+(machine-0)  start
+Starting emulation...
+(machine-0)
+```
+
+## Quitting Headless Renode Session
+
+To quit the session, just type `quit` into the telnet prompt:
+
+```
+(machine-0) quit
+Renode is quitting
+Connection closed by foreign host.
+```
+
+This will quickly exit both telnet and the renode process on this port.
