Ah, I see the commit that renamed the repo[1] because the title says "Memos" and the URL says "/memos" but the repo was different. I similarly got confused while reading the readme thinking Pensieve was a dependency or something
Sorry for the confusing. I gave a bad name "memos" for the project. But there is a great open source project named "memos" over there. So I quickly changed the name to "Pensieve".
