+## Getting started
+
+Celestia will start up in a window, and if everything is working correctly,
+you'll see Earth in front of a field of stars.  Displayed on-screen, is some
+information about your target (Earth), your speed, and the current time
+(Universal Time, so it'll probably be a few hours off from your computer's
+clock).
+
+Right drag the mouse to orbit Earth and you might see the Moon and some
+familiar constellations.  Left dragging the mouse changes your orientation
+also, but the camera rotates about its center instead of rotating around
+Earth.  Rolling the mouse wheel will change your distance to Earth--you can
+move light years away, then roll the wheel in the opposite direction to get
+back to your starting location.  If your mouse lacks a wheel, you can use the
+Home and End keys instead.
+
+When running Celestia, you will usually have some object selected.  Currently,
+it's Earth, but it could also be a star, moon, spacecraft, galaxy, or some
+other object.  The simplest way to select an object is to click on it.  Try
+clicking on a star to select it.  The information about Earth is replaced with
+some details about the star.  Press G (or use the Navigation menu), and you'll
+zoom through space toward the selected star.  If you press G again, you'll
+approach the star even closer.
+
+Press H to select our Sun, and then G to go back to our Sun.  Right click on
+the sun to bring up a menu of planets and other objects in the solar system. 
+After selecting a planet from the menu, hit G again to travel toward it.  Once
+there, hold down the right mouse button and drag to orbit the planet.
+
+The Tour Guide is a list of some of the more interesting objects you can visit
+in Celestia.  Select the Tour Guide option in the Navigation menu to display
+the Tour Guide window.  Choose a destination from the list, click the Goto
+button, and you're off.
+
+That covers the very basics.  For a more in-depth look at Celestia and the
+controls available to you, download the "Celestia User's Guide" (written by 
+Frank Gregorio), available in several languages, from:<br>
+  https://celestia.space/guides.html<br>
+This web page also includes links to the Celestia README file translated into
+Japanese.
+
+### Star browser
+By default, the Star Browser window displays a table of the 100 nearest stars,
+along with their Distance, Apparent and Absolute Magnitude, and Type. Clicking
+on the column headers will sort the stars.  The table is not continuously
+updated, so if you travel to another star, you should press the Refresh button
+to update the table for your current position.  The radio buttons beneath the
+table let you switch between viewing a list of Nearest, Brightest, or 'With
+planets' stars.  As with the solar system browser, clicking on any star name
+in the table will select it.  Use this feature along with the Center and Go
+To buttons to tour the stars visible from any night sky in the galaxy.
+
+### Solar system browser
+The Solar System Browser displays a window with a tree view of all the objects 
+in the nearest solar system (if there is one within a light year of your current
+position.)  Clicking on the name of any object in the window will select it.  
+You can then use the Center or Go To buttons to display that object in the main 
+Celestia window.
+
+### Selecting objects by name
+Celestia provides several ways to select an object by name...
+1. Choose 'Select Object' from the Navigation menu, type in the object name, and click OK.
+2. Press Enter, type in the entire object name, and press Enter again.
+3. Press Enter, type in the first few characters of the object name,
+press the Tab key to move through the displayed listing until the object is highlighted,
+then press Enter again.
+ 
+You can use common names, Bayer designations or catalog numbers for stars.
+Celestia currently supports the HIP, HD and SAO catalogs. Catalog numbers must 
+be entered with a space between the prefix and the catalog number.
+
+### Known issues
+For up-to-the-minute answers to some common problems encountered when running
+Celestia, please view either the FAQ in the Help menu or take a look at the 
+"Celestia User's FAQ" located on the Celestia User's Forum: 
+https://celestia.space/forum/
+
+### User modifiable elements
+You can modify how Celestia starts up each time you run it, by defining your
+own start-up settings.  Simply open the file "start.cel" in a plain text
+editor and follow the in-file instructions.  Also, view the celestia.cfg file
+in a plain text editor to see additional settings.
+
+Celestia allows you to easily add real, hypothetical, or fictional objects
+by creating new catalog files. It is *not* recommended that you alter the
+built-in data files; nearly all desired modifications and additions can be
+made by placing new catalog files in Celestia's extras folders. There are three
+types of catalog files:
+* ssc (solar system catalog: planets, moons, spacecraft, etc.)
+* stc (star catalog)
+* dsc (deep sky catalog: galaxies, star clusters, and nebulae)
+
+All three types of catalog file are text files that can be updated with your
+favorite text editing program.
+
+### Building from sources
+See instructions in file [INSTALL.md](INSTALL.md).

-## Getting started
+* https://github.com/CelestiaProject/Celestia
 
-Celestia will start up in a window, and if everything is working correctly,
-you'll see Earth in front of a field of stars.  Displayed on-screen, is some
-information about your target (Earth), your speed, and the current time
-(Universal Time, so it'll probably be a few hours off from your computer's
-clock).
+See also: `README-upstream`, `README-upstream.md`.
 
-Right drag the mouse to orbit Earth and you might see the Moon and some
-familiar constellations.  Left dragging the mouse changes your orientation
-also, but the camera rotates about its center instead of rotating around
-Earth.  Rolling the mouse wheel will change your distance to Earth--you can
-move light years away, then roll the wheel in the opposite direction to get
-back to your starting location.  If your mouse lacks a wheel, you can use the
-Home and End keys instead.
+## License/Copyright
+GPLv2+
 
-When running Celestia, you will usually have some object selected.  Currently,
-it's Earth, but it could also be a star, moon, spacecraft, galaxy, or some
-other object.  The simplest way to select an object is to click on it.  Try
-clicking on a star to select it.  The information about Earth is replaced with
-some details about the star.  Press G (or use the Navigation menu), and you'll
-zoom through space toward the selected star.  If you press G again, you'll

+# Debian
+Package was removed from Debian in the ancient days due to bitrot.
+The upstream code has a new team and active development, using
+recent libraries. The package can be built under Debian Ok, except
+for the `data/` files.
 
-The Tour Guide is a list of some of the more interesting objects you can visit
-in Celestia.  Select the Tour Guide option in the Navigation menu to display
-the Tour Guide window.  Choose a destination from the list, click the Goto
-button, and you're off.

+```
+Upstream has not produced any new releases in the last 4 years. In the
+mean time, the package is accumulating bugs due to bitrot. It already
+wasn't a trouble-free package, due to some quite important resources not
+being DFSG compliant.
+```
 
-### Solar system browser
-The Solar System Browser displays a window with a tree view of all the objects 
-in the nearest solar system (if there is one within a light year of your current
-position.)  Clicking on the name of any object in the window will select it.  
-You can then use the Center or Go To buttons to display that object in the main 
-Celestia window.
+I do see some of the resources now are CC-by-SA 4.0, a license which
+didn't exist when the Debian bug was created. So it may be that it
+can be built happily without DFSG issues using new data files.

+Celestia depending on NASA's Spice/NAIF may be afoul of Debian's
