 Plotting in the terminal is supported via UnicodePlots with
 coordinates generated by ViennaRNA.
 
+
+```julia
+using UnicodePlots, PlotRNA
+PlotRNA.uniplot("(((...)))")
+```
+
 Note: this is still considered experimental.  There are still some
 problems with plot sizes and aspect ratios. Additionally, when calling
 `uniplot` with an illegal structure or unbalanced parentheses it is
 possible to produce a segfault (coming from `plot_coords` in ViennaRNA
 that is used to generate coordinates for plotting).  See:
 [https://github.com/marcom/ViennaRNA.jl/issues/13](https://github.com/marcom/ViennaRNA.jl/issues/13).
