Below you will find lecture slides for a workshop on modeling intensive longitudinal data, as well as files you can use to practice analyzing intensive longitudinal data.
It includes practicals for R and for Mplus, for n=1 models or multilevel models. Regardless of which software you use, I would recommend starting with the n=1 model files, before practicing with the multilevel models.
For the Mplus exercises, some basic knowledge of Mplus is recommend, and I'd recommend to also watch some of the webinars available on the mplus website (https://www.statmodel.com/TimeSeries.shtml), where they also discuss model code.
For the R exercises, basic knowledge of R is recommended (if you do not know the basics, consider the Introduction to R workshop above).
(Some) basic knowledge of Bayesian stats is also very helpful, because both the analyses in Mplus and in R are Bayesian.
