IXBRL, what does it change for me?

Hi,

I have been trawling the web for answers but I am still a bit in the dark on IXBRL.

I have a limited company that doesn't have a lot of activity at all, just some very simple income and costs is all what's in the accounts.

Every year I do the webfiling and I submit a paper version of my accounts to HMRC.

Now the new IXBRL thing comes in and:  http://www.hmrc.gov.uk/ct/ct-online/file-return/xbrl-guide.pdf  this guide is not very clear in my opinion.

Can somebody maybe explain in bulletpoints:

- If I can use the free software by HMRC to file accounts?
- Is there any reason for me to buy any software to be compliant with the iXBRL  standard?

Thanks,

Andries
