 # Pingbot
 
-A Mastodon bot for pinging
+Pingbot monitors a Mastodon account, and will ping one or more other accounts any time
+that account gets a notification. This is useful for monitoring an admin account that
+may not be logged in all the time, or for checking in on an old account after you've
+made a new one.
+
+## Setup
+
+**On the account you want to monitor**, open Preferences, then Development, and click
+the New Application button at the upper right.
+
+You'll need to give your application a name; this can be pretty much anything you want.
+Leave "Application website" blank, and leave "Redirect URI" alone.
+
+You can leave Scopes alone; all Pingbot does is check your notifications and send you
+DMs. However, if you want to limit Pingbot's access for security, it **must** have 
+`read:notifications` and `write:statuses` in order to do its job.
+
+Click the Submit button at the bottom, and you'll see "Application successfully created",
+as well as your new application in the list below. Click the name you chose (it should be
+blue), and this will bring up a screen that shows you the **client key**, **client secret**,
+and **access token**.
+
+In Pingbot's directory, copy `sample-config.cfg` to `config.cfg`, and then open it for
+editing. You'll need a separate header in the config file, enclosed by [brackets], for
+each bot you want to run in the same directory. The sample configuration file includes
+a [pingbot] header for you, as well as a [DEFAULT] header for settings that apply to
+every bot in the directory. You should place most of your information under the 
+[pingbot] header; the configuration file includes instructions on how to do this.
+(Note that what the Mastodon web interface calls a "Client key", the config file
+calls a `client_id`.)
+
+In the configuration file, every username you include should *not* have an @ before it
+(e.g. `noelle@elekk.xyz`, not `@noelle@elekk.xyz`).
+
+Once all your information is in the configuration file, save it, and then run
+
+`ananas config.cfg`
+
+in a terminal window and your bot will start up and begin listening! In Linux, you can
+run your bot in the background by adding an & to the end:
+
+`ananas config.cfg &`
+
+Or you can use a window manager like `tmux` or `screen`, which will let you keep the
+bot running on a server without you havnig to be logged in.
+
+## Making configuration changes
+
+If you want to change Pingbot's settings, you'll need to stop and restart the bot. 
+Make sure you stop the bot *before* you make changes; Pingbot saves its configuration
+when it shuts down, and might overwrite your changes.
