+# slweb
+
+**Slweb** is a static website generator which aims at being simplistic. It uses
+**sed**(1) to transform a custom Markdown-like syntax into HTML.
+
+## Install
+
+```
+$ git clone https://github.com/Strahinja/slweb.git
+$ cd slweb
+$ make && sudo make install
+```
+
+## Examples
+
+See the `[examples/](https://github.com/Strahinja/slweb/tree/master/examples)` directory in this repository.
+
+Given the file `index.slw` in the current directory:
+
+```
+site-name: Test website
+site-desc: My first website in slweb
+---
+\
+\{main}
+\# Hello world
+\
+This is an \_example_ of a statically generated HTML.
+\
+\{/main}
+```
+
+after using the command:
+
+```
+$ slweb index.slw > index.html
+```
+
+file `index.html` contains:
+
+```
+&lt;!DOCTYPE html&gt;
+&lt;html lang="en"&gt;
+&lt;head&gt;
+    &lt;title&gt;Test website&lt;/title&gt;
+    &lt;meta charset="utf8" /&gt;
+    &lt;meta name="description" content="My first website in slweb" /&gt;
+    &lt;meta name="viewport" content="width=device-width, initial-scale=1" /&gt;
+    &lt;meta name="generator" content="slweb" /&gt;
+&lt;/head&gt;
+&lt;body&gt;
+\
+&lt;main&gt;
+&lt;h1&gt;Hello world&lt;/h1&gt;
+\
+&lt;p&gt;This is an &lt;em&gt;example&lt;/em&gt; of a statically generated HTML.&lt;/p&gt;
+\
+&lt;/main&gt;
+&lt;/body&gt;
+&lt;/html&gt;
+```
