+~log
+====
+
+Use **squigglelog** to easily create a simple log for your tilde. [Create new posts](https://github.com/thebaer/squigglelog/tree/master/entries#squigglelog-entries) in the `entries/` folder, then run this:
+
+```bash
+go build squigglelog.go
+./squigglelog -template mysquigglelog
+```
+
+This will use any template in `templates/` defined with _mysquigglelog_ (see below) to generate your full squigglelog page.
+
+#### templates
+
+Your template should look like this.
+
+```html
+{{define "mysquigglelog"}}
+<html>
+	<head>
+		<title>My ~log!</title>
+	</head>
+	<body>
+		<h1>~log</h1>
+		<p>Welcome to my ~log.</p>
+		{{template "log" .}}
+	</body>
+</html>
+{{end}}
+```
