reporting linear mixed effects


I am fitting a linear mixed effects model to data of a psycholinguistic experiment in which participants had to rate the naturalness of past tense forms for nonsense verbs.
Carrying out the statistical procedures went quite okay, but I have some trouble figuring out which information and which values I should give when I report the analysis and the results.
Are there already any "official" guidelines for reporting LME somewhere out there? If that is not the case, is there any experienced statistician who could tell me what they would like to see reported for an LME?
