Transform steps documentation

[aborruso]

Hi,
first of all thank you again and again for this great project.

I use it especially via CLI, but I think that this is a more general issue.

Reading Transforming Data, I have this yaml pipeline:

tasks:
  - type: resource
    source: countries.csv
    steps:
      - code: cell-replace
        fieldName: neighbor_id
        pattern: '22'
        replace: '2'
      - code: cell-replace
        fieldName: population
        pattern: 'n/a'
        replace: '67'
      - code: row-filter
        formula: population
      - code: field-update
        name: neighbor_id
        type: integer
      - code: table-normalize
      - code: table-write
        path: countries.csv

Some notes about it:

• above we have row-filter, and the formula is simply population. If I understand correctly then all the records with non-null values are filtered. Where can I read the documentation on this? Here I do not have any sentences about formula syntax;
• above we have cell-replace, and I have 3 parameters: fieldName, pattern and replace. Where can i find which parameters can be used for each step? I have neither here nor there.

I am available to help update the documentation, if there is anything I can get this kind of information from.

Thank you
