 Nginx doesn't generate etags for static content.  I think it should.  If I can remember enough C from college to make it work as a module, I will.
 
-This does not work yet.
+### Installation
 
-It will not work for quite some time, if ever.  But it's a fun way to play a bit with C again.
+Download the module however you like.  I'd recommend pulling it down with Git by simply cloning this repository:
+
+    mkdir ~/src
+    cd    ~/src
+    git clone git://github.com/mikewest/nginx-static-etags.git ./nginx-static-etags
+
+To use the module, you'll have to compile it into Nginx.  So, download the Nginx source, configure it with the module path, and compile:
+
+    mkdir ~/src
+    cd ~/src
+    curl -O http://sysoev.ru/nginx/nginx-0.6.32.tar.gz
+    tar -zxvf ./nginx-0.6.32.tar.gz
+    cd ./nginx-0.6.32
+    ./configure --add-module=/Users/mikewest/Repositories/nginx-static-etags
+    make
+    sudo make install
+    
+And you're done!
+
+### Configuration
+
+Add `FileEtag` to the relevant `location` blocks in your `nginx.conf` file:
+
+    location / {
+        ...
+        FileETag on;
+        ...
+    }
+
+It's currently an on/off toggle.  The plan is to bring it to feature parity with [the Apache configuration option][apache].  It's really not there yet.
