 - 🔍 Process search and filtering
+
+  Search for processes by name, command, or PID. Search for multiple things at once by separating them with commas. For
+  example, `arm, x86` will return processes having `arm` or `x86` as a substring of the name or command. You can use
+  regular expressions too. For example, `d$` will return a list of daemons (which tend to end in the letter `d`), while
+  `(\w+)\.\w+` will return a list of processes with reverse domain name notation, such as `com.docker.vmnetd`.
