Hi! Here is small "How to" again. Suppose you need to share something with source code. How can we manage it on DC? **Sharing code snippets** 1. Add normal post (not Code Package). 2. Paste your code in the post and format it with highlighting as it is [described here](https://community.intersystems.com/post/how-highlight-cach%C3%A9-objectscript-work-html-and-other-questions). 3. If you see that your COS code is highlighted wrong it means that autodetect missed with language. Open the post's HTML ("disable rich-text" button below the Editor) and put class=COS parameter into the code tag. Example:
#dim test as %Library.Integer 
SET test = 123.099 
set ^global = %request.Content 
Write "Current date """, $ztimestamp, """, result: ", test + ^global = 125.099 
do ##class(Cinema.Utils).AddShow("test") // class method call do ##super() 
; another one-line comment 
d:(^global = 2) ..thisClassMethod(1, 2, "test") 
/* * Sub-languages support: */ 
 &sql( SELECT * FROM Cinema.Film WHERE Length > 2 )
 &js<for (var i = 0; i < String("test").split("").length); ++i) { 
   console.log(i); 
   }> 
 &html< 
<html>
  
<body>
Test
</body> 
</html>>
 quit $$$OK

4. If you want to highlight another languages and auto highlight works not as expected put the appropriate [code class](https://highlightjs.org/static/demo/). **Sharing projects and solutions with sources** If you want to share with something significant like demo project do the following: 1. Upload your code on Github in a public repository. [Example](https://github.com/intersystems/CacheUpdater).  Use Atelier to upload COS projects in UDL. If you are using Caché Studio there are plenty of Git Plugins. Try one of the most popular - [Caché Tortoise Git.](https://github.com/intersystems/cache-tort-git) 2. Add normal post and  share the link on Github in it. People will fork your repository, will do pull requests, will download it and more. **Code** **guidelines** Suppose you have your own code guidelines. If not, we can suggest guidelines listed [in this repository.](https://github.com/intersystems-ru/cos-guidelines)
