+## Installing prerequisites
+
+If you are on Windows, instead of using the commands below you can also use our [pre-configured Vagrant box](https://github.com/status-im/nim-vagrant) if you prefer to run things in a Linux environment.
+
+We use Makefiles to quickly and easily build our binaries. Before you begin, please make sure you have [RocksDB installed](https://github.com/status-im/nimbus#rocksdb). On Windows, you can skip this step and instead rely on the "WINDOWS ONLY" part of the process below:
+
+```bash
+git clone https://github.com/status-im/nimbus
+cd nimbus
+make update # Downloads and builds submodules, dependencies, and even Nim itself
+
+# >>> WINDOWS ONLY <<<
+make fetch-dlls # WINDOWS ONLY
+# >>> WINDOWS ONLY <<<
+
+./env.sh bash # Optional, but useful. Sets the current shell's environment to use the version of Nim language the `make update deps` command just built
+```
+
+### Building and Running Nimbus
+
+To run Nimbus in Ethereum 1.0 mode:
+
+```bash
+make nimbus
+./build/nimbus
+```
+
+Nimbus will now run and attempt to synchronize with the Ethereum 1.0 blockchain. It can currently reach block 1.5 million.
