 ## How to use
 
 1. Set your settings in `settings.go`
-2. Modify (if you want)
+2. Modify the application (if you want)
 3. Compile `go get && go build -o server`
-4. Place your content into `entries/`
+4. Place your `.txt` files into `entries/` (see section "Formatting" below)
 5. Run `./server`
 6. put behind a proxy (or don't).
 
+### Formatting
+
+The only formatting option you have: to define a title.
+
+```
+Title: A title
+
+here comes the entry body ...
+```
+
+It has to be defined in the first line of the text file.  
+If you don't define a title, the filename without the `.txt` part gets used as the title.
+
 ## Requirements
 
 Developed and tested on Linux. Should work on other Unixoids.
