+# Agents.jl
+Agents.jl is a pure Julia framework for agent-based modeling (ABM): a computational simulation methodology where autonomous agents react to their environment (including other agents) given a predefined set of rules. 
+
+## Setup
+After installing julia, navigate to the `examples/Agents.jl` directory:
+```
+julia
+using Pkg
+Pkg.activate(".")
+```
+if this is the first time using the package you'll need to install the dependencies:
+```
+Pkg.instantiate()
+```
+otherwise, you can skip to importing a model e.g.,:
+```
+include("ModelA.jl")
+import .ModelA
+ModelA.run_model()
+```
