-## Codestyle
-
-- Code will be in [ECMAScript 2020](http://www.ecma-international.org/ecma-262/9.0/)
-- Style rules are specified in [ESLint](.eslintrc.yml)
-
-<!--
-## Identifiers
-
-Marked with `?` means it could change/be removed.
-
-### Field types
-
-Field type conversion happens when a step is saved. Expected inputs are all basic types JSON allows.
-
-- `INPUT` leave as is
-- `TEXT` convert to text
-- `INTEGER` convert with `parseInt`
-- `FLOAT` convert with `parseFloat`
-- `TIME` convert to ISO-formatted string `Date.toISOString()` output
-
-### Input types
-
-This defines the input interface for each step entry.
-
-- `FIELD`
-- `SELECT`
-
-### Display types
-
-This defines the way the field information is displayed to the user.
-For example if we know a field to be currency, we could add a suffix here so that instead of just the number they see `123,00€`.
-
-- `CURRENCY?`
-
-### Generator types
-
-- `STATIC` just pass through the `parameters.value` and don't even sweat
-- `TIME_NOW?` this could change as well. every step has an internal createdAt timestamp anyway...
-- `TIME_RELATIVE_PREVIOUS?` mostly for playing around for now
-
-### Report
-
-- aggregations: `COUNT|MIN|MAX|AVG|SUM`
-- intervals: `YEAR|MONTH|WEEK|DAY|HOUR|MINUTE|SECOND`
