>### *A [discord.py](http://discordpy.readthedocs.io/en/latest/) bot focused on providing CTF tools for collaboration in Discord servers (ctftime.org commands, team setup + ctfd integration, utilites, etc)!  If you have a feature request, make it a GitHub issue or use the >request "x" command.*

[Invite to your server](https://discordapp.com/oauth2/authorize?client_id=455502163452362753&permissions=268528720&scope=bot)

#  How to Use
*If you ever forget a command, use `>help`!*

After inviting to your server, it is recommended that you first configure the categories you want active and archived CTF channels to go into.
* When you create a ctf, it will by default go into the "CTF" category (it will create one if it is not present), and when you archive a ctf it will go into the ARCHIVE category.
* You can configure this with `>config ctf_category "Category for CTFs"` and `>config archive_category "Category for Archived CTFs"`

## CTF Commands

The following commands are the ones you will most likely want to pay attention to, although if you do not expect to use this bot to manage CTFs you can skip this category and go down to CTFTime commands.

* `>ctf create "ctf name"`  This is the command you'll use when you want to begin a new CTF.  This command will make a text channel with your supplied name under the designated CTF category. *Must have permissions to manage channels*

*NOTE: the following ctf specific commands will only be accepted under the channel created for that ctf.  This is to avoid clashes with multiple ctfs going on in the same server.*

 * `>ctf join/leave` Using this command will either give or remove the role of a created ctf to/from you.

 * `>ctf challenge add/working/solved/remove "challenge"` Allows users to add or remove challenges to a list, and then set the status of that challenge. *Use quotations*

  * `>ctf challenge list` This is the list command that was previously mentioned, it displays the added challenges, who's working on what, and if a challenge is solved (and by who).

  > NOTE: There is shorthand!  challenge -> chal/chall, add -> a, working -> w, solved -> s, remove -> r
 
* `>ctf challenge pull "http(s)://ctfd.url"` Pull challenges and their solved states from a CTFd hosted CTF, and add them to your challenges list.  Requires the username and password to be set with `>ctf setcreds "username" "password"`

* `>ctf setcreds "ctfd username" "password"` Pin the message of ctf credentials, can be fetched by the bot later in order to use `>ctf challenge pull`.  Credentials are never stored outside of Discord.

* `>ctf creds` Gets the credentials from the pinned message.

> *IMPORTANT: credentials are never stored outside of the pinned message on Discord. They are needed to pull challenge data and solve state from the CTFd platform.*


* `>ctf archive` Move the CTF channel into the Archive category.  *Must have permissions to manage channels*

* `>ctf delete` Delete the CTF info from the database, and delete the role. *Must have permissions to manage channels*
