+plocate is a locate based on posting lists, consuming mlocate's database
+ahead-of-time and making a much faster (and smaller) index out of it.
+It supports most mlocate options; see --help or the man page (man -l plocate.1)
+for more information.
 
-Alpha stage; file format is subject to change. To build, run
+plocate is in beta. The file format is stable, but may still change
+(if so, plocate will notify you itself that you need to rerun
+plocate-build). To build and install, you will need a C++17 compiler
+and a development package for Zstd (https://facebook.github.io/zstd/).
+liburing (https://github.com/axboe/liburing) and a kernel supporting
+io_uring (Linux 5.1 or newer) is optional, but strongly recommended
+for best performance, especially if you do not have an SSD. Installation
+is run as:
 
   meson obj
   cd obj
   ninja
+  sudo ninja install
+
+To build the database for the first time after install, you can do
+
+  sudo /etc/cron.daily/plocate
+
+or equivalently, run the update-plocate.sh script from the source
+directory as root (it is the same file installed to /etc/cron.d).
