-# Tarstats-pp
+# Tarstats-++
 Tool to provide stats of a tarball.
+http://github.com/blindi815/Tarstats-pp
+Version: v1.0.1-FixRelease
 
-## Info
+## General information
 This is a little command line tool to provide statistics on a GNU tar file. It is a personal project to further self study programming using C++.
 
 The project is inspired by https://github.com/isotopp/tarstats by @github/isotopp and the Twitter thread https://twitter.com/isotopp/status/1489549907841146882
 
-## Goal
-Goal is to provide stats like total amount of files/ directories and printing them out to stdout, a plain text file and JSON. Support for GNU zip compressed files will come too.
+### Limitations
+This tool works on standard .tar files as well on tarfiles compressed by GNU zip. Other compression methods are not supported. This does not yet parse tarballs inside a tarball.
 
+## Prerequisites
+Building this requires a version of zlib (http://zlib.net) on the target system. Common Linux distributions include zlib, yet the dev portions might be missing and have to installed first. In case of Ubuntu `zlib1g-dev`. Consult the provider of the distribution of your choice.
+
+## Installation
+```
+cmake .
+sudo cmake --build .
+sudo cmake --install .
+```
+
+## Usage
+```
+$ tarstats_pp
+usage: tarstats-pp [-h] [-j] [-f] tarfile [tarfile...]
+A tool to calculate basics statistics on tarball. Shamelessly inspired by github.com/isotopp/tarstats!
