 This will open a browser window that will allow you to login or create an account. By default this command will login to the production environment, but the command accepts an argument for a different host URL if needed (e.g. for beta testing purposes).

+## Upload files
+
+The CLI can be used to upload files to Quantum Inspire. These files can both be hybrid and quantum circuits.
+
+```bash
+qi files upload <filename> <backend_id>
+```
+
+The CLI will assume that files with the extension `.cq` are quantum circuits, while files with a `.py` extension are python files. For the `backend_type` use any of the id's in the list below:
+
+* QX emulator, id = 1
+* Spin-2+, id = 2
+* Starmon-7, id = 3
+
+## Get results
+
+The previous command outputs a job ID for the job that was just started. Use this job ID when querying for results.
+
+```bash
+qi results get <job_id>
+```
+
+**Note**: Mostly useful for quantum circuits.
+
+## Get final results
+
+A job also always contains a final result. This object can be queried with the following command.
+
+```bash
+qi final_results get <job_id>
+```
+
+**Note**: This object will always be generated. In the case of a quantum circuit, the result and final result will be the same. For hybrid algorithms, the final result is a free form datastructure that could for example be used for the aggregation of data. This is generated in the `finalize` step.
