-# lat
-> lat | lazy cat - a cat clone with some quality-of-life embellishments
-
-## About
-
-`lat` is a solution to a problem that doesn't exist. It's the awkward middle child in-between `cat` and `bat`. It was created because the author didn't want to have to configure `bat` just to get decent file printing, but wanted a little more control than `cat` offered.
-
-`lat` does not expect to be used. `lat` expects to be forgotten and shunted into a corner because it does not belong in the slightest.
-
-## Install
-`lat` is not yet at a stable version (`v1.0.0`), so it is not on any package managers. 
-
-```bash
-git clone https://github.com/secondary-smiles/lat.git
-
-cd lat
-
-make
-
-./build/lat -V
-
-# now add lat to your $PATH/do whatever you want with the binary
-```
-
-## Helptext
-> `lat -h`
-
-```text
-lat | lazy cat - a cat clone with some quality-of-life embellishments
-
-usage: lat [-cltbrpneVh] [file...]

-options:
-	-c           toggle color
-	-l           toggle line numbers
-	-t           toggle file info headers
-	-b           set binary mode, -b forces binary and -bb forces NOT binary
-	-r           print everything (headers, line numbers, etc.) to stdout (or equivalent)
-	-p           print file with the pager (uses less)
-	-n <name>    manually set the name of the file shown in the title
-	-e <program> link extension to lat
-	-V           show program version
