 	GullapConsole -i my/Path/To/My/Site
 	GullapConsole -g my/Path/To/My/Site
 	GullapConsole -g
+	GullapConsole -f my/Path/To/A/File
 
 The argument `-i` generates the necessary structure within `my/Path/To/My/Site`. Therefore the target path has to exist. It is not created by gullap. The file structure looks like the following
 
 	Site
 	|- assets
 	|- output
 	|- pages
+	|- posts
 	|- templates
 
 Copy all your necessary assets (CSS, JavaScript, Images) into `assets`. They will be copied to the `output` directory as they are. So, if you have sub directories they will be available also within the output directory. The `pages` directory contains your markup. Per default they should contain all your Markdown files (the extension of your files is unimportant, as all files are taken for the transformation). Put all your Nustache templates to the `templates` directory. 
 
 After you filled up the structure with all necessary files, call `GullapConsole` with argument `-g` and the path to your site directory. Everything will be generated to the `output` directory. In case you use `-g` without giving a site path, the current directory will be used as the site path.
 
+Using the parameter `-f` you can define a single file to be builded. The parameter needs a file path. This can either be an absolute path, a relative one or just the filename. In that case the first file matching the given name will be built, so take care if there are more having this name.
+
+Use `GullapConsole -h` you can show help information. Add `-v` to your commands to get the full output.

 There is one template that MUST exist: `page.template`. This is the default template. Use `template` to override that.
