Involvement in the development of ZAP is actively encouraged!
You do not have to be a security expert in order to contribute.

Some of the ways you can help:

While ZAP is becoming increasingly popular, there are still many people who could benefit from it who havnt heard about it.

You can help by:

• Blogging about ZAP
  
• Tweeting about ZAP (be sure to include @zaproxy)
  
• Starring and/or G+1'ing this project (and zap-extensions)
  
• Reviewing ZAP in sites like ohloh
• Telling people you use it
  
• Giving talks about it - and let us know if you need help with slides etc

Please raise new feature requests as enhancement requests here: https://github.com/zaproxy/zaproxy/issues
If there are existing requests you are also interested in then please 'star' them - that way we can see which features people are most interested in and can prioritize them accordingly.

Please use the zaproxy-develop Google Group for feedback:

• What do like?
  
• What don't you like?
  
• What features could be made easier to use?
  
• How could the help pages be improved?
  
• Examples of vulnerabilities that ZAP doesn't detect
  
• Examples of false positives that ZAP incorrectly flags

Ideally we'd like example vulnerabilities and false positives in the same format as the ZAP Web Application Vulnerability Examples: https://github.com/zaproxy/zaproxy/wiki/Downloads but if you're not good with JSPs then we'll accept them in any format if necessary!

Have you had a problem using ZAP?
If so and its not already been logged then please [report it](https://github.com/zaproxy/zaproxy/issues) Are you fluent in another language?
Can you help translate ZAP into that language?
If so then just go to http://crowdin.net/project/owasp-zap and get stuck in

If you fancy having a go at adding functionality to ZAP then please get in touch via the
zaproxy-develop Google Group.
We have a list of projects on this wiki ideal for people new to ZAP to work on.
Also have a look at some notes about providing new Scanner Rules.
Again, you do not have to be a security expert to contribute code - working on ZAP
could be great way to learn more about web application security!
If you actively contribute to ZAP then you will be invited to join the project.
