-You can use "exe" mode (flag `-e`):
-for example, to comment out in C++
-every line containing `my_bad_var`,
-then delete the line above it:
+Ever wish you could simply apply a vim command to every line
+in a command output automatically?
+If you use vim as your primary editor, this is likely much much easier
+than having to look up sed commands every time you filter a command output.
 
-```
-cat my_script.cpp | vims -e 'my_bad_var' 'I//\<esc>kdd'
-```
+E.g., `cat file.txt | vims -l 'f|d$'` will go through every line, and run "f|d$",
+which is the vim command for deleting every character after "|". 
+See below for many other useful features.
 
-Which translates to `vims '%g/my_bad_var/exe "norm I//\<esc>kdd"'` - the `I` being the command
-to start insert at the start of the line, and `//` being the comment sequence.
-`\<esc>kdd` pushes the escape key, moves up a line, then deletes the line.

-```
-> echo 'Hello World!' | vims -s 'ea Beautiful'

+To install, put `vims` somewhere on your path, e.g., `/usr/bin`.
 
-- `-s` - Turn on simple mode (normal vim commands, start at char 0, line 0)
-- `ea` - Start inserting after end of first word

+- (default) `-t [EX_CMD]` Ex mode. Works as if you typed ":" in vim.
+- `-s [CMD]` Simple command mode. Starts on the first line in command mode (e.g., `x` deletes a char).
+- `-l [CMD]` Line command mode. Runs the command on every line. 
+- `-e [REGEX] [CMD]` Exe mode. Runs the command on every line matching `REGEX` (uses vim regex).
+- `-r [REGEX] [CMD]` Inverse exe mode. Runs the command on every line not matching `REGEX` (uses vim regex).
+- `-n` quiet. Don't print lines to stdout. You will then have to use `:p` command to print manually.
+
+Note that for commands, you can write `\<esc>` to hit the escape key, or `\<c-o>` to hit ctrl-O.
