README.md

## data-intermediate

Because some json files are huge, we use tar.zst to package the data.

1. to compress the data

```bash
tar -I 'zstd' -cvf data-intermediate.tar.zst --exclude='*.md' data-intermediate/ # exclude README.md and challenging_parsing.md
```

2. to decompress the data to `your_folder/`

first you should make sure `your_folder/` exist. If not, create it.

silently
```bash
tar -I 'zstd -d' -xf data-intermediate.tar.zst -C your_folder/
```
or, with progress verbose
```bash
zstd -d -c data-intermediate.tar.zst | tar -xvf - -C your_folder/
```
