Thank you for interest in ChomCHOB

We have 2 part for testing your DevOps skill, programming and operation part. When you done this test you need to create repository like in "example submission" folder on your github repository.

This test contain with 2 part.

• This is not decentralized wallet so no need to worry about blockchain stuff.
• If some of detail or requirement are ambiguous, we so sorry about that. And feel free to use your creative thinking to do that stuff.

If you implement the programming part complete, this is your operation part. Here is requirement we want.
