+# Bootstrapping example with bootstrapping nodes
+
+This is an example that shows how to connect to a list of bootstrapping nodes.
+
+## Run the example
+
+1. Run `make` and `make deps` in the main directory
+2. Run `go build` in this directory to build the executable
+3. Run `./bootstrapping-railing` in this directory in order to start the programm
