-If you are running this quickstart with a self managed Couchbase cluster, you need to [load](https://docs.couchbase.com/server/current/manage/manage-settings/install-sample-buckets.html) the travel-sample data bucket in your cluster and generate the credentials for the bucket.

+To begin this tutorial, clone the repo and open it up in the IDE of your choice. Now you can explore about how to interact with Couchbase Server using the C++ SDK.
 
 We have separated out the SDK code and the main function. The `db.h` and `db.cpp` contain the declaration and the implementation of utility functions we will use to parse environment variables and create a connection to the cluster. `operations.h` and `operations.cpp` contain all the functions that perform operations on the db. Both `db.cpp` and `operations.cpp` are combined to make a static library. The tests are similarly separated out in the `tests` folder which utilise the library created earlier. The `main.cpp` is the executable which is also built by linking the library and contains code that demonstrates the usage of the functions we defined earlier to initeract with the db.
