Reading the neck

Colour says which string, from the high e (top, as in tab) to the low E. The dot's row and the tab line say it again.
A clear dot is on its way. Over its last second a ring in the string's colour closes round it.
A lit dot means play now. The ring round it runs out with the note: that is how long to hold it.
Wait for me: the board dims and the notes to play sit in a turning dashed ring until you play them; then the song goes on.
Score my playing (Options, View; off to begin with): a tick marks what you got and a cross what was wrong; playing along while the song runs, "early" or "late" says how you were off, and a note you let go by turns grey with a cross.
The bracket under the fret numbers is your hand: four frets from the index finger. On an upright phone the view follows it; drag the neck sideways to look elsewhere.

Space or Step moves one note or chord and plays it; Shift+Space goes back. P plays or pauses, W turns waiting on or off. L loops the next few seconds from where you are (again for the stretch after it, Shift+L for the one before). Tap the tab to jump; drag across it to loop that stretch. Tap the fretboard to play a note (with Wait for me, tap what is lit).

How the marks are worked out

Most MIDI files don't say how a note was played, so these marks are guesses from timing and pitch. Each one has a confidence; the slider under Guitar hides the weak ones. What you see is also what you hear.

Hammer-on (h) / pull-off (p): two notes in a row on the same string, the second starting while the first still sounds or less than 40 ms after it, 1 to 5 frets apart, and no louder. Up the neck is a hammer-on, down is a pull-off. Overlap and a softer second note raise the confidence. When nearly every note in the part is joined like this (common in transcriptions), it says little, so the confidence drops.
Slide (sl.): joined notes on the same string with a pitch-bend glide between them (sure), or a jump bigger than 5 frets (a guess).
Bend (½, full): pitch bend rising on a held note. ½ is one semitone, full is two. A bend that comes back down is a bend and release; one already up when the note starts is a pre-bend (PB).
Vibrato (~): pitch bend that swings up and down several times on one note.
Palm mute (P.M.): a picked note shorter than 0.1 s, well before the next note on its string.
Strings: files that put each string on its own channel (channels 1 to 6) are read string by string; the licks are written that way. Otherwise a search picks the frets: it keeps your hand in one position, prefers small moves, keeps chords within a stretch of about four frets, and slightly prefers lower frets.
