 **MultilayerGraphs.jl** implements the mathematical formulation of multilayer graphs proposed by [De Domenico et al. (2013)](https://doi.org/10.1103/PhysRevX.3.041022). It mainly revolves around two custom types, [`MultilayerGraph`](@ref) and [`MultilayerDiGraph`](@ref), encoding undirected and directed multilayer graphs respectively.
 
-Roughly speaking, a multilayer graph is a collection of ***layers***, i.e. graphs whose vertices are representations of the same set of nodes, and ***interlayers***, i.e the [bipartite graphs](https://en.wikipedia.org/wiki/Bipartite_graph) whose vertices are those of any two layers and whose edges are those between vertices of the same two layers. See below for the distinction between ***nodes*** and ***vertices***.
+Roughly speaking, a multilayer graph is a collection of *layers*, i.e. graphs whose vertices are representations of the same set of nodes, and *interlayers*, i.e the [bipartite graphs](https://en.wikipedia.org/wiki/Bipartite_graph) whose vertices are those of any two layers and whose edges are those between vertices of the same two layers. See below for the distinction between ***nodes*** and ***vertices***.
 
 [`MultilayerGraph`](@ref) and [`MultilayerDiGraph`](@ref) are fully-fledged [Graphs.jl](https://github.com/JuliaGraphs/Graphs.jl) extensions. Both structs are designed so that their layers and interlayers can be of any type (as long as they are Graphs.jl extensions themselves) and they need not be all of the same type. It is anyway required that all layers and interlayers of [`MultilayerGraph`](@ref) and [`MultilayerDiGraph`](@ref) are respectively undirected and directed. Directedness is checked via the `IsDirected` trait defined in Graphs.jl adopting [SimpleTraits.jl](https://github.com/mauro3/SimpleTraits.jl). Since the layers' and interlayers' graph types don't need to be the same, multilayer graph types are considered weighted graphs by default, and thus are assigned the trait `IsWeighted`.
