if you want to bookmark a page while reading a particular chapter..there's the "bookmark it" option at the top right corner (three lines)
Do you mean a chapter or the Manga itself, either way, here's how to do both. Chapter: go to whatever chapter you want to bookmark and click the 3 stripes on the top right of your screen.how to bookmark a manga: click on whatever manga and just scroll down until you see these and click whichever one.
