Love the louvered pergola! Some parts are timely during assembly such as the louvers. I am female and assembled it by myself mostly. I did have to have help standing the main posts and attaching the tops rails until to make it stable for me to anchor it down. They are heavy and if they fall there will be damage to your house :). I could not use the expansion anchors provided because I attached it to my deck. The anchors they provide are probably good for thick concrete. I anchored after all frame pieces were standing.  So instead I got large lag bolts that worked perfect 1/2" x 3". I will find out how this holds up on the next wind storm..I did double block where I put the anchors for extra support.
