-## Requirements
+The function uses a Table in an Azure Storage Account to store the `messageId` of the last message posted for each callsign. If that message was posted recently (as defined by `LOOKBACK_SECONDS`), it will _update_ the message instead of posting a new one to reduce the chatter of the bot.
 
-- Python 3.x
-- Azure Functions
-- requests
+You can find a live, working version of this bot in the [Cascadia Radio](https://www.cascadiaradio.org/) Discord server, in the `#spots` channel. Join us!
 
 ## Config
 
-The Azure Function App expects one environment variable: `TARGET_URL`, which should be the webhook URL from the target Discord channel.
+The Azure Function App expects three environment variables: 
+- `TARGET_URL` - the webhook URL from the target Discord channel.
+- `LOOKBACK_SECONDS` - the number of seconds to look backwards for previous messages to update instead of posting a new one
+- `TABLE_NAME` - the name of the table in the Azure Storage Account where the last messageIds will be stored for each callsign
+
+## Deploy Notes
+
+- Some basic tests run in `tests.py` on the creation of a new PR
+- To deploy, manually run `main_hamalertspotbot.yml`
+    - This will deploy to the staging slot for testing. 
+    - The staging `TARGET_URL` points to my private Discord server
+    - `LOOKBACK_SECONDS` is set to only 300 (instead of 7200) for easier testing.
