Very clear and straightforward and to-the-point documentation. Great stuff!

Any code changes in ```server``` folder, simply run

```
python visualdl/server/visualDL --logdir={LOG_DIR} --port=8080

So I had a problem on this step wherein it was importing libraries from the pip installed version of visualDL. So I had to resolve it by resetting my PYTHONPATH. You don't need to explain it as much as it would be nice if it is mentioned in a comment.

When to read needn't be synced or controlled, because the R/W conflicts happen rarely, and the web service can be retriggered a few times, that is a cheap but relatively not bad way to assure read service reliability.

The read service should not affect the writing service, that is the key.

- ```Record``` : represent any data structure for any component
- Handles the actual logic to serialized to disk and deserialized from disk
- ```storage.proto```: protobuf file that defines the exact interface to be read/write
