-# TLE - Two Line Element
-NASA/NORAD Two line element set framework
+# TLE PHP
 
-A two-line element (TLE) is a set of two data lines listing orbital elements that describe the state (position and velocity) of an Earth-orbiting object. The TLE data representation is specific to the Simplified perturbations models (SGP, SGP4, SDP4, SGP8 and SDP8) so any algorithm using a TLE as a data source must implement one of the simplified perturbations models to correctly compute the state of an object at a time of interest.
+Client for NASA TLE API (http://api.nasa.gov/) and TLE framework implemented in php.
 
-Parser usage:
+# About
+
+The TLE API provides up to date two line element set records, the data is updated daily from [CelesTrak](https://celestrak.com/) and served in JSON format. A two-line element set (TLE) is a data format encoding a list of orbital elements of an Earth-orbiting object for a given point in time. For more information on TLE data format visit [Definition of Two-line Element Set Coordinate System](https://spaceflight.nasa.gov/realdata/sightings/SSapplications/Post/JavaSSOP/SSOP_Help/tle_def.html).
