 ### IterableTables
-The call to ``load`` returns a ``struct`` that is an [IterableTable.jl](https://github.com/davidanthoff/IterableTables.jl), so it can be passed to any function that can handle iterable tables, i.e. all the sinks in [IterableTable.jl](https://github.com/davidanthoff/IterableTables.jl).

+The following code shows an example of loading a bedGraph file into a [DataFrame](https://github.com/JuliaData/DataFrames.jl):

 ### Using the pipe syntax

 ```julia
 using FileIO, BedgraphFiles, DataFrame
 
 df = load("data.bedgraph") |> DataFrame
 ```
 
 To save an iterable table, one can use the following form:
-
 ```julia
 using FileIO, BedgraphFiles, DataFrame
 
-df = # Aquire a DataFrame somehow
+df = # Aquire a DataFrame somehow.
 
 df |> save("output.bedgraph")
 ```
 
 The `save` method returns the data provided or `Vector{Bedgraph.Record}`. This is useful when periodically saving your work during a sequence of operations.
-
 ```julia
 records = some sequence of operations |> save("output.bedgraph")
 ```
 
-The pipe syntax is especially useful when combining it with [Query.jl](https://github.com/davidanthoff/Query.jl) queries. For example, one can easily load a Bedgraph file, pipe it into a query, then pipe it to the `save` function to store the results in a new file.
