+# Docs
+
+Welcome to the docs. Not docks, [no docker yet](#docker).
+
+## Usage
+
+### Extensions
+
+First, find some extensions. You'll need a checker to check whether something is up, a logging extension to log stuff, and optionally an extension to send alerts. Extensions are specified on a per-service basis, so you can mix-and-match extensions as much as you want. Once there are some real extensions I'll list some here.
+
+### Config
+
+Then create a `services.json` file for your config, like this:
+
+```json
+{
+    "site": {
+        "name": "A Website",
+        "checker": "CheckerTemplate",
+        "checker-args": {
+            "url": "https://example.net",
+            "port": 443,
+            "lol": "CheckerTemplate ignores these options lol"
+        },
+        "rate": 1,
+        "alerts": "AlertsTemplate",
+        "alerts-args": {
+            "url": "https://example.com/webhook-url-or-whatever-goes-here",
+            "lol": "irrelevant, AlertsTemplate ignores these options lol"
+        },
+        "logging": "LoggingTemplate",
+        "logging-args": {
+            "file": "/home/askiiart/Documents/updog/logs/site-log"
+        }
+    }
+}
+```
+
+Required arguments:
+
+- The key (in this case `site`): A unique string to identify the service in logs, also used internally.
+- `checker`: The name of the checker extension's *class*.
+- `checker-args`: Arguments for the checker. Check the checker's docs for what to put here.
+- `rate`: How often to check if the service is up (every *x* seconds)
+- `alerts`: The name of the alerting extension's *class*.
+- `alerts-args`: Arguments for the alerting extension. Check the alerter's docs for what to put here.
+- `logging`: The name of the logging extension's *class*.
+- `logging-args`: Arguments for the logging extension. Check the logger's docs for what to put here.
+
+Optional arguments:
+
+- `name`: A human-friendly name for the service; currently unused.
+
+---
+
+This example uses the template extensions, [askiiart/updog-checker_template](https://git.askiiart.net/askiiart/updog-checker_template), [askiiart/updog-logging_template](https://git.askiiart.net/askiiart/updog-logging_template), and [askiiart/updog-alerts_template](https://git.askiiart.net/askiiart/updog-alerts_template), so the arguments for them are mostly irrelevant. For each extension, check its docs for what arguments to use.
+
+### Running it
+
+Just run it with `python3 updog.py`
+
+### Docker
+
+No Docker yet, Updog throws `RuntimeError: can't create new thread at interpreter shutdown` when I try to run it in Docker. So no Docker until I figure that out.

-# Alerts Extensions
+# Logging Extensions
 
 Updog doesn't do any monitoring by itself. Instead, extensions are used to check the status of whatever thing, send alerts, and log stuff. Updog just chains them together.
