 ## Usage
 
+Just a short version of this:
+
+```sh
+zcat /data/data/com.termux/files/usr/share/man/man1/cmake.1.gz | groff -mandoc -Thtml > cmake-man.html
+```
+
+To find out man page paths use `whereis` command:
+
+```sh
+$ whereis cmake
+
+cmake: /data/data/com.termux/files/usr/bin/cmake /data/data/com.termux/files/usr/share/man/man1/cmake.1.gz
+```
+
 `man2html` takes the name of a manpage as an argument, so you don't need to specify the manpage by its path.
