 # Telegram Bot
 
 - Deletes messages matching specified patterns
-- Bans users for posting messagses matching specified patterns
+- Bans users for posting messages matching specified patterns
 - Bans users with usernames matching specified patterns
-- Records logs of converstations
+- Records logs of conversations
+- Logs an English translation of any foreign languages using Google Translate
+- Uses textblob for basic sentiment analysis of both polarity and subjectivity
 
 ## Installation

 - `pip install --upgrade -r requirements.txt`
 
 ## Database setup

 - Store database URL in environment variable.

 ```
 export TELEGRAM_BOT_POSTGRES_URL="postgresql://<user>:<password>@localhost:5432/<databasename>"
 ```

 - Run: `python model.py` to setup the DB tables.

 - Create your Telegram group.
 - Add your bot to the group like so: https://stackoverflow.com/questions/37338101/how-to-add-a-bot-to-a-telegram-group
 - Make your bot an admin in the group
 
-## Configuring patterns
+## Configuration with ENV vars
 
-- Regex patterns will be read from the following env variables
+- `MESSAGE_BAN_PATTERNS` : **REQUIRED** Regex pattern. Messages matching this will ban the user.
-	- `MESSAGE_BAN_PATTERNS` Messages matching this will ban the user.
+- `MESSAGE_HIDE_PATTERNS` : **REQUIRED** Regex pattern. Messages matching this will be hidden/deleted
-	- `MESSAGE_HIDE_PATTERNS` Messages matching this will be hidden/deleted
+- `NAME_BAN_PATTERNS` **REQUIRED** Regex pattern. Users with usernames or first/last names maching this will be banned from the group.
-	- `NAME_BAN_PATTERNS` Users with usernames or first/last names maching this will be banned from the group.
+- `CHAT_IDS` : **REQUIRED**. Comma-seperated list of IDs of chat(s) that should be monitored. To find out the ID of a chat, add the bot to a chat and type some messages there. The bot log will report an error that it got messages `from chat_id not being monitored: XXX` where XXX is the chat ID. e.g. `-240532994,-150531679`
-	- `SAFE_USER_IDS` User ID's that are except from these checkes. Note that the bot cannot ban admin users, but can delete their messages.
+- `TELEGRAM_BOT_TOKEN` : **REQUIRED**. Token for bot to control. e.g. `4813829027:ADJFKAf0plousH2EZ2jBfxxRWFld3oK34ya`
+- `TELEGRAM_BOT_POSTGRES_URL` : **REQUIRED**. URI for postgres instance to log activity to. e.g. `postgresql://localhost/postgres`
+- `DEBUG` : If set to anything except `false`, will put bot into debug mode. This means that all actions will be logged into the chat itself, and more things will be logged.
+- `ADMIN_EXEMPT` : If set to anything except `false`, admin users will be exempt from monitoring. Reccomended to be set, but useful to turn off for debugging.
+- `NOTIFY_CHAT` : ID of chat to report actions. Can be useful if you have an admin-only chat where you want to monitor the bot's activity. E.g. `-140532994`
+- `CMC_API_KEY`: If you want the `/price` bot command to work, make sure to set a CoinMarketcap API key
+
+## Download the corpus for Textblob
+
+For sentiment analysis to work, you'll need to download the latest corpus file for textblob. You can do this by running:
+
+```
+python -m textblob.download_corpora
+```
+
+If you're running the bot on Heroku, set an environment variable named `NLTK_DATA` to `/app/nltk_data` by running:
+
+```
+heroku config:set NLTK_DATA='/app/nltk_data'
+```
+
+## Message ban patterns
 
 Sample bash file to set `MESSAGE_BAN_PATTERNS`:
+
 ```
 read -r -d '' MESSAGE_BAN_PATTERNS << 'EOF'
 # ETH Address
@@ -52,11 +84,17 @@ read -r -d '' MESSAGE_BAN_PATTERNS << 'EOF'

 ```
 
+## Attachments
+
+By default, any attachments other than images or animations will cause the message to be hidden.
+
 ## Running
 
 ### Locally
+
 - Run: `python bot.py` to start logger
 - Messages will be displayed on `stdout` as they are logged.
 
 ### On Heroku
+
 - You must enable the worker on Heroku app dashboard. (By default it is off.)
