 ## Setup
 The Python prerequisites for running tlapbot are the libraries `flask`,
 `requests` and `apscheduler`.
-### First time setup
-Install prerequisites:
-```bash
-pip install flask
-pip install requests
-pip install apscheduler
-```
-(Or install them in your virtual environment if you prefer to use one)

-Initialize db:
+### Dev setup (from git repository)
+1. Clone the repository.
+2. Run `pip install -e .` in the root folder. This will install tlapbot
+as a package in editable more, along with all its prerequisites.
+3. Initialize db:
     ```bash
     python -m flask init-db
     ```
-Create an `instance/config.py` file and fill it in as needed.
+4. Create an `instance/config.py` file and fill it in as needed.
 Default values are included in `tlapbot/default_config`, and values in
 `config.py` overwrite them. (The database also lives in the `instance` folder
 by default.)
 
-Tlapbot will probably not work if you don't overwrite these:

-OWNCAST_INSTANCE_URL
+    OWNCAST_INSTANCE_URL # default points to localhost owncast on default port

+## Owncast setup
 In Owncast, navigate to the admin interface at `/admin`,
 and then go to Integrations.
-#### Access Token
+### Access Token
 In Access Tokens, generate an Access Token to put in
 `instance/config.py`. At the moment, the only permission the Access Token needs
 is sending messages, the bot doesn't perform any administrative actions.
-#### Webhook
+### Webhook
 In webhooks, create a Webhook, and point it at your bot's URL with
 `/owncastWebhook` added.

+In debug, pointing the External Action to an address like `localhost:5000/dashboard` might not work because your localhost address doesn't provide https, which owncast requires.
