Getting Help

EPUBcheck may seem like software for digital publishing professionals and you may encounter doubts or problems using it, but don't worry, there are several ways to ask for help:

• If you have difficulty interpreting the messages in the EPUBcheck report – which can sometimes be a bit cryptic – you can refer to the message guide
• If you still you still have doubts on the meaning of the messages or if you encounter problems running EPUBcheck, you can try asking the #eprdctn community: it's an informal group of nice folks that work in the digital publishing field (from all over the world); we are sure there will be someone ready to answer you.
• Finally, if the problem seems unsolvable, you can open an issue on Github, where the EPUBcheck developers are listening, to fix all the bugs of the tool
