bash: inception: command not found

[DerZc]

Now I can run the docker of Inception and run the simple guide successfully. But when I run the Tutorial in step Fourth
inception --elf ./lpc18xx-demos/bin.elf --bitcode ./lpc18xx-demos/bin.bc \ --allocate-determ --allocate-determ-start-address 0x90000000 --allocate-determ-size 10000 \ --mem_conf_file ./mem.json --interrupt_conf_file ./irq.json
I meet the error
bash: inception: command not found,
how can I do?
