 cl-yag stands for Common Lisp Yet Another Generator and obviously it's written in Common Lisp.

+## The hierarchy
 
 Here are the files and folder of cl-yag :
  
 + **Makefile** : exists to simplify your life (updating, cleaning) 
-+ **generator.lisp** : contains all the code of the generator 
-+ **templates/** : contains .tpl files which are used as template for the html structure 
-+ **static/** : contains static files that need to be made public like images, css, js etc...
-+ **data/** : contains what will make the content of your website different from another website (or not) 
-  + **articles.lisp** : contains metadata about the website and the list of the articles with their id/title/date/(author/short description) (aren't mandatory) 
-  + **${id}.txt** : contains the html text of the article ${id} that will be used when displayed 
-+ **output** : this is where the websites goes when your run *make*, and where it's cleaned when you run *make clean*; You can make it a symbolic link to the web server folder.

-# How to add an article
- 
-Edit data/articles.lisp and add a new line inside the *articles* variable like this
+# Usage
 
-    (list :id "2" :date "29 April 2016" :title "How do I use cl-yag" :author "Solène" :short "I will explain how to use the generator" :tag "example help code")
+## How to add an article
+ 
+Edit data/articles.lisp and add a new line inside the *articles* variable like this (you can do it in one line, as you prefer)
+
+    (list :title "How do I use cl-yag" 
+	      :id "2" :date "29 April 2016" 
+	      :author "Solène" 
+		  :short "I will explain how to use the generator" 
+		  :tag "example help code")
 
 The _:short_ field is used on the homepage. It it is defined, this is the text that will be shown on the homepage with all the others articles. If it's not defined, the whole article content will be used on the homepage. Sometimes when you have long articles, you may not want to display it entirely on the index so you can use _:short "view the article for the full text_.
 
+The _:id_ field will be part of the filename of the file and it's also the name of the content on the disk. `:id "2"` will load file `data/2.txt`, you can use text instead of numbers if you want.
+
 The _:author_ field is used to display who wrote the article. You can omitt it, the generator will take the name from the *config* variable
 
-The _:tag_ field is used to create a page with all the articles with the same tag. You can omitt it if you don't want it tagged. Tags can't contain spaces.

-# How to hack it
+## How to publish
 
-I tried to make it "hacking friendly" so it's very extensible. 
+There is a makefile, all you need to do is to type "make" in the folder, this will create the files in the **output/** location (which can be a symbolic link to somewhere else). If you want to use a different lisp interpreter (default is **sbcl**), you can set the variable LISP to the name of your binary. 
+
+Example with clisp : 
+
+`make LISP=clisp`
+
+This way, you can easily use a git hook to type make after each change in the repo so your website is automatically updated.

+# Some hacks you can do

+I tried to make it "hacking friendly", you can extend if easily. If you have any idea, feel free to contact me or to send patches.

-# Known limitation
+# Known limitations
+
+## Use of ~ character
 
 The application will crash if you use a single "**~**" caracter inside one data structure in **articles.lisp** files. This is due to the format function trying to interpret the ~ symbol while we just one a ~ symbol. This symbol in the others files are automatically replaced by ~~ which produce a single ~. So, if you want to have a "~" as a title/url/author/description/short/date you have to double it. It may be interestind to sanitize it in the tool maybe.

+## Article without tag
+
+You can have a page without a tag associated but in the default template you will have a line under the title which will displays "Tags : " and no tags after.
