-# Unmaintained bots
-
-This directory contains bots that are currently not maintained by the Zulip
-community. They are untested and potentially buggy or completely nonfunctional.
-We only know that they worked at the time of their creation.
-
-We see potential in every bot included in this directory. Many were moved simply
-because they didn't contain automated tests. Feel free to use or revive
-these bots.
-
-## Reviving a bot
-
-To revive an unmaintained bot, go through our [Writing bots](
-https://chat.zulip.org/api/writing-bots) guide and check if
-the bot meets the outlined criteria.
-In particular, this means that the bot should:
-* contain automated tests.
-* be well-documented, with usage examples.
-* provide a command set reasonably easy and convenient to use for a human.
-
-Once a bot fulfills all the criteria, feel free to submit a pull request to add it
-to the `bots` directory. We are happy to include it there.

-# FourSquare Bot
-
-* This is a bot that returns a list of restaurants from a user input of location,
-proximity and restaurant type in that exact order. The number of returned
-restaurants are capped at 3 per request.
-
-* The list of restaurants are brought to Zulip using an API. The bot sends a GET
-request to https://api.foursquare.com/v2/. If the user does not correctly input
-a location, proximity and a restaurant type, the bot will return an error message.
-
-* For example, if the user says "@foursquare 'Chicago, IL' 80000 seafood", the bot
-will return:
-
-Food nearby 'Chicago, IL' coming right up:
-
-    Dee's Seafood Co.
-    2723 S Poplar Ave, Chicago, IL 60608, United States
-    Fish Markets
-
-    Seafood Harbor
-    2131 S Archer Ave (at Wentworth Ave), Chicago, IL 60616, United States
-    Seafood Restaurants
-
-    Joe's Seafood, Prime Steak & Stone Crab
-    60 E Grand Ave (at N Rush St), Chicago, IL 60611, United States
-    Seafood Restaurants
-
-* If the user enters a wrong word, like "@foursquare 80000 donuts" or "@foursquare",
-then an error message saying invalid input will be displayed.
-
-* To get the required API key, visit: https://developer.foursquare.com/overview/auth
-for more information.

-# Howdoi bot
-
-This bot will allow users to get technical answers from
-[StackOverflow](https://stackoverflow.com). It is build on top of the
-python command line tool [howdoi](https://github.com/gleitz/howdoi) by
-Benjamin Gleitzman.
-
-## Usage
-
-Simply prepend your questions with one of the following commands. The
-answer will be formatted differently depending the chosen command.
-
-| Command                 | Respond                                                |
-| ----------------------- | ------------------------------------------------------ |
-| `@mention-bot howdowe`  | Concise answer to the same stream.                     |
-| `@mention-bot howdowe!` | Same as `@mention-bot howdowe` but with full answer and URL of the solutions. |
-| `@mention-bot howdoi`   | Concise answer replied to sender via private message.  |
-| `@mention-bot howdoi!`  | Same as `@mention-bot howdoi` but with full answer and URL of the solutions. |
-
-## Screenshots
-
-#### Example 1
-
-Question -> `@mention-bot howdowe use supervisor in elixir`
-
-  ![howdowe question](assets/question_howdowe.png)
-
-Answer ->  Howdoi would try to **only** respond with the coding section
-of the answer.
-
-  ![howdowe answer](assets/answer_howdowe.png)
-
-#### Example 2
-
-Question -> `@mention-bot howdoi! stack vs heap`
-
-  ![howdoi! question](assets/question_howdoi_all.png)
-
-Answer -> Howdoi would return the **full** stackoverflow answer via
-**private message** to the original sender. The URL of the answer can be
-seen at the bottom of the message.
-
-  ![howdoi! answer](assets/answer_howdoi_all.png)
-
-**Note:**
-
-* Line wrapped is enabled with a maximum line length of 85 characters.
-This could be adjusted in the source code (`HowdoiHandler.MAX_LINE_LENGTH`).
-
-* *Howdoi* generally perform better if you ask a question using keywords
-instead of a complete sentences (eg: "How do i make a decorator in Python"
--> "python decorator").
-
-* __[*Limitation*]__ If a answer contains multiple code blocks, the `@mention-bot howdoi`
-and `@mention-bot howdowe` commands would only return the first coding section, use
-`@mention-bot howdo[we|i]!` in that case.

-John
-
-Instructions:
-You'll have to install chatterbot to use this bot.
-Please run: pip install chatterbot on your command line.
-The script will need to download some NLTK packages after running in your
-home directory. With the mission of humanizing bot interactions, John aims to be your
-virtual assistant at the hour of asking for help in Zulip. John is an
-interactive bot that uses machine learning heuristics to simulate a
-conversation with the user. He has a great sense of humor and
-is also powered by Open Source code!
-
-![Joke John](assets/joke.png)
-
-How it works?
-John is initially trained with Corpus files, or large text files.
-Dialogues are loaded into a json "database", he will try to follow them
-once it receives input from a user. John will query the database and
-try to find the response that best matches the input according to the Levenshtein distance
-which is a string metric for measuring the difference between two sequences. If several
-responses have the same acurracy, he will choose one at random.
-
-![Meet John](assets/greetings.png)
-
-Can he learn by himself?
-John's engine allows him to learn from his conversations with people. However,
-without strict supervision bots that learn from people can do harm, so learning
-is currently restricted to his initial corpus.
