 There are two GitHub Action pipelines for [Continuous Integration(CI)](ci.yml) and [Continuous Deployment(CD)](cd-training-pipeline.yml) of the ML pipeline on Vertex AI environment. 
 
 **CI**: This is to verify the proposed changes of the pipeline by creating and compiling through [TFX CLI](https://www.tensorflow.org/tfx/guide/cli). Specifically, `tfx pipeline create` and `tfx pipeline compile` returns errors if the codes of the pipeline has import/syntax problems. 
-- You can furthure improve CI pipeline by actually run the pipeline locally with `tfx run create`. However, in this case, you need to consider the code structure to be able to set epochs and datasets differently. You certainly don't want to run the pipeline over the long epochs and full dataset since the purpose of CI is to check if there is no problem.
+You can also _run_ the pipeline locally with `tfx run create`. However, in this case, you need to consider the code structure to be able to set the number of epochs and datasets differently. You certainly don't want to run the pipeline over for a larger number of epochs and on the full dataset since the purpose of CI is to check if there is no problem.
 
 **CD**: This runs the pipeline on Vertex AI environment. In order to give more flexibility, it leverages the `workflow_dispatch` feature of GitHub Action which allows you to set some parameters manually via GitHub Action UI. In this project, there are four parameters as below(`gcpProject`, `gcpRegion`, and `pipelineName` are used in `tfx run create` TFX CLI):
 - `gcpProject`: This sets which GCP Project ID to run the pipeline on Vertex AI. This GCP Project ID is going to be used to authenticate your credentials to login and send requests to Vertex AI. The credentials(JSON) should be provided in GitHub Action Secret, and the key for the GitHub Action Secret should be the same to the value of `gcpProject` except that dash character( `-` ) should be replaced by underscore( `_` ). `-` is not an allowed character in a GitHub Action Secret key.
