How to post

Posting a question or starting a discussion in the ST Community is simple and should look familiar to you if you have used an online community in the past - or even a standard text editor!

Hover your mouse over a category of the community from the top navigation bar:

• Product forums for technical questions.

  

   

• Select the board concerned by your question.  
• Click on “Start a post” on the community's homepage. 

You will now see the posting area as described below: 
 

1. This is the title of your post.  
   - Use relevant and descriptive keywords to help users know what the rest of your post is about, and keep it short, ideally under 70 characters. 
   - You will be able to add more information in the Body section. 
2. This is the title of your post.  
   - Add a detailed description of your issue including the steps you have already taken to try to fix it. The more details, the better. Using the buttons at the top of this area, you can add links, code samples, images, lists, etc. 

3. Select the board concerned by your post. 

4. Add relevant tags (the full list of tags below).  

5. Click on “Create” to publish your question.
