-zyGrib is a Visualization of meteo data from files in GRIB Format 1
+zyGrib is a program to download and visualize meteorological forecast data in
+the standard formats GRIB 1 and 2. The available datasets include NOAA-GFS
+(weather and wind conditions, above ground and at altitude) and FNMOC-WW3 (wave
+conditions). It is possible to create animations from the forecast data of the
+selected region and to export them as a set of images.
 
-Available meteo infos (W and CH - *):
+The available data include:
 
-    Surface Pressure (*)
-    Wind 10 m above mean sea level (*)
-    Wind gust (*)
-    Temperature 2 m above mean sea level (*)
-    Potential Temperature min - max 2 m above mean sea level
-    Relative Humidity 2 m above mean sea level (*)
-    Total Precipitation (mm/h) (*)
-    Total Cloud Cover (%) (*)
-    Dew Point 2 m above mean sea level (*)
-    0C Isotherm
-    Snow (Depth - Risk)
-    CAPE (convective available potential energy) at earth level (*)
-    Data in altitude (850 (*), 700 (*), 500 (*), 300, 200 hPa) : geopotential
-        altitude, wind (*), temperature (*), theta-e, relative humidity (*).
-    Waves : height, direction, period, whitecap probability, for wind waves,
-        swell, and for significant, maximum, primary, secondary waves. 
+- Mean sea level pressure
+- Wind 10m above surface
+- Wind gusts
+- Temperature 2m above surface
+- Minimum and maximum temperature 2m above surface
+- Relative humidity 2m above surface
+- Total precipitation (mm/h)
+- Cloud cover (%)
+- Dew point 2m above surface
+- 0 deg C isotherm
+- Snow (rain-snow line and snowfall risk)
+- CAPE (convective available potential energy) and CIN (convective inhibition)
+- Data at altitude (wind, temperature, theta-e, geopotential altitude, relative
+  humidity) at 925, 850, 700, 600, 500, 400, 300 and 200 hPa levels
+- Atmospheric sounding forecast displayed on SkewT-LogP thermodynamic diagrams
+- Waves (height, direction, period, whitecap probability for wind waves, swell,
+  and for significant, maximum, primary and secondary waves)
+- Sea currents (not provided by zyGrib's data server)
+
+The zyGrib source package ships with the code for Qwt (an extension library for
+QT) and NOAA's g2clib (decoder/encoder routines for GRIB 2): both are built
+automatically and linked statically: this will not affect already installed
+libraries.
