 ## How it works ?
 
-An app project is an item of object wwws, a web component (wco) is an item of object wco.<br>
-To make an app project on line http://appname.tribename.townname.nationname/pagename_lg.html,  nginx conf must be set in tribename/nginx/appname.tribename.townname.nationname.conf <br>
+- An app project : an item of object wwws
+- A web component (wco) : an item of object wco.
+
+### wwws   -  appname
+
+- wwws/{appname}/src source file of the app
+- wwws/{appname}/src/{pagename}_{lg}.html  the webpage in specific language lg
+- wwws/{appname}/src/static/css/input.css  contain the tailwind and daisyUI personnalisation (https://daisyui.com/theme-generator)
+- wwws/{appname}/src/tpldata/{pagename}/{wcoid}_{wconame}_{lg}.json  data personalisation of a component wconame for an HTML element with id=wcoid
+- wwws/{appname}/dist  build from the source (src forlder)
+- wwws/itm/{appname}.json  context of the app  that contain all data needed to personnalize the wco
+
+To make an app project in line http://appname.tribename.townname.nationname/pagename_lg.html :
+
+ -  nginx conf must be set in tribename/nginx/appname.tribename.townname.nationname.conf
+ -  for dev /etc/hosts must contain 127.0.0.1 appname.tribename.townname.nationname 
+ -  for prod a DNS must redirect to the apxtri server
+
+### wco  - web component
+
+-  wco/{wconame}/{wconame}.js  the engine that make wco is render depending of template 
+-  wco/{wconame}/{tplname}[_{lg}].mustache  a mustache template can be language dependant or independant (data are in json) 
+-  wco/{wconame}/example{tplname}_{lg}.json a data example to customize the wco
+
+
+### wwws and wco
+
+In /adminapi/package.json 2 scripts:
+
+```
+{
+    "src:css": "npx @tailwindcss/cli -i ../$tribe/objects/wwws/$webapp/src/static/css/input.css -o ../$tribe/objects/wwws/$webapp/src/static/css/output.css --watch",
+    "dist:css": "node apxtri/models/Wwws.js $tribe $webapp dist && tailwindcss --minify -i ../$tribe/objects/wwws/$webapp/src/static/css/input.css -o ../$tribe/objects/wwws/$webapp/dist/static/css/output.css"
+}
+# To dev :  it produces wwws/{appname}/src/static/css/output.css  on the flight when something change in an html, js, mustache as well in a wco called in an html.
+$ tribe=adminapi webapp=admin yarn src:css
+
+# To build : it minifies output.css in dist and merge, minify, uglify all js used and optimize image, manage language (THIS IS UNDER CONSTRUCTION)  
+$ tribe=adminapi webapp=admin yarn dist:jscss
+
+```  
+
+
+
 Then the webapp can get context data with the endpoint http://appname.tribename.townname.nationname/api/adminapi/wwws/updatelocaldbanonymous/tribename/appname/pagename/versionnumber  this will return in data a set of data parameter into tribename/objects/wwws/itm/appname.json
