Duplicated building instructions
Building instructions are provided in two files:
Instructions are more detailed in building.md file, but instructions for building Orekit through Ant are only provided in the BUILDING.txt file. Since the README.md file proposed in merge request !3 (merged) directs users to the building.md file, the missing instructions should be added to it and the BUILDING.txt file deleted.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
