HORIZONS is provided by the Solar System Dynamics Group of\n the Jet Propulsion Laboratory.\n\u003e\n\u003e \u0026mdash; \u003ccite\u003e[NASA's documentation for the HORIZONS system][HORIZONS]\u003c/cite\u003e\n\nThe only ways to access HORIZONS are through `telnet`, email, and\na CGI web interface intended for end-user access.\nI want to provide a modern REST-style JSON interface to this system.\n\n## Install\n\nClone this repository via Git\n\n```sh\ngit clone https://github.com/Cantido/horizons.git\n```\n\n## Usage\n\nThis application contains its own Jetty web server.\nTo start in Production mode, use the provided `start-server.sh` script.\n\n```sh\n./start-server.sh\n```\n\nYou can also run this app in development mode with `lein run`\n\n```sh\nlein run -m horizons.main\n```\n\n## Maintainers\n\nThis project is maintained by [Rosa Richter](https://github.com/Cantido).\nYou can get in touch with her on [Keybase.io](https://keybase.io/cantido).\n\n## Contributing\n\nQuestions and pull requests are more than welcome.\nI believe bad documentation is a bug,\nso if anything is unclear, please [file an issue](https://github.com/Cantido/horizons/issues/new)!\nIdeally, my answer to your question will be in an update to the docs.\n\nPlease see [CONTRIBUTING.md](docs/CONTRIBUTING.md) for all the details you could ever want about helping me with this project.\n\nNote that this project is released with a Contributor [Code of Conduct](docs/CODE_OF_CONDUCT.md).\nBy participating in this project you agree to abide by its terms.\n\n## License\n\nMIT License\n\nCopyright 2020 Rosa Richter.\n\nPermission is hereby granted, free of charge, to any person obtaining a copy of\nthis software and associated documentation files (the \"Software\"), to deal in\nthe Software without restriction, including without limitation the rights to\nuse, copy, modify, merge, publish, distribute, sublicense, and/or sell copies\nof the Software, and to permit persons to whom the Software is furnished to do\nso, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all\ncopies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
