-## Outputs
-
-First output is response from nosql engine and second is the data passed in.
-
-## Collection
-
-if the collection field is left empty, then we try to look at \`flowdata.get('collection')\`, to set this value you need to use \`flowdata.set('collection', '<collection-name>')\` in previous component (currently only \`function\` can be used)
-
-## Insert
-
-- will insert recieved data
-- expects data to be an Object
-- returns error, success, id
-
-## Read
-
-- will read a document by id
-- expects data to be an Object with an \`id\` property
-- returns error, response
-
-## Update
-
-- will update document by id
-- expects data to be an Object with \`id\` property and all the props to be updated
-- returns error, response
-- if response is 0 then update failed
-
-## Remove
-
-- will remove document by id
-- expects data to be an Object with an \`id\` property
