 **To use the latest development version of MicrobeAgents it's required to manually install
 the latest version of Agents first (`]add Agents#main`).**
 
+**Documentation deployment is currently broken due to dependency on unreleased Agents.jl version; you can build it locally with the following code (requires the LiveServer.jl package):**
+```
+git clone https://github.com/mastrof/MicrobeAgents.jl.git
+cd MicrobeAgents.jl
+julia --project=docs/ -e 'import Pkg; Pkg.instantiate(); Pkg.add(name="Agents", rev="main"); include("docs/make.jl")'
+julia -e 'using LiveServer; serve(dir="docs/build")'
+```
