+
+## Installation
+
+AVA is an incredibly lightweight protocol, so the minimum computer requirements are quite modest.
+
+- Hardware: 2 GHz or faster CPU, 3 GB RAM, 250 MB hard disk.
+- OS: Ubuntu >= 18.04 or Mac OS X >= Catalina.
+- Software: [Go](https://golang.org/doc/install) version >= 1.13.X and set up [`$GOPATH`](https://github.com/golang/go/wiki/SettingGOPATH).
+- Network: IPv4 or IPv6 network connection, with an open public port.
+
+### Native Install
+
+Ubuntu users need the following libraries:
+
+* libssl-dev
+* libuv1-dev
+* cmake
+* make
+* curl
+* g++
+
+Install the libraries:
+
+```sh
+sudo apt-get install libssl-dev libuv1-dev cmake make curl g++
+```
+
+#### Downloading Gecko Source Code
+
+Clone the Gecko repository:
+
+```sh
+cd $GOPATH
+mkdir -p src/github.com/ava-labs
+cd src/github.com/ava-labs
+git clone https://github.com/ava-labs/gecko.git
+cd gecko
+```
+
+#### Building the Gecko Executable
+
+Build Gecko using the build script:
+
+```sh
+./scripts/build.sh
+```
+
+The Gecko binary, named `ava`, is in the `build` directory. 
+
+### Docker Install
+
+- Make sure you have docker installed on your machine (so commands like `docker run` etc. are available).
+- Build the docker image of latest gecko branch by `scripts/build_image.sh`.
+- Check the built image by `docker image ls`, you should see some image tagged
+  `gecko-xxxxxxxx`, where `xxxxxxxx` is the commit id of the Gecko source it was built from.
+- Test Gecko by `docker run -ti -p 9651:9651 gecko-xxxxxxxx /gecko/build/ava
+   --public-ip=127.0.0.1 --snow-sample-size=1 --snow-quorum-size=1 --staking-tls-enabled=false`. (For a production deployment,
+  you may want to extend the docker image with required credentials for
+  staking and TLS.)
+
+## Running Gecko and Creating a Local Test Network
+
+To create your own local test network, run:
+
+```sh
+./build/ava --public-ip=127.0.0.1 --snow-sample-size=1 --snow-quorum-size=1 --staking-tls-enabled=false
+```
+
+This launches an AVA network with one node.
+
+You should see some pretty ASCII art and log messages.
+You may see a few warnings. These are OK.
+
+You can use `Ctrl + C` to kill the node.
+
+If you want to specify your log level. You should set `--log-level` to one of the following values, in decreasing order of logging.
+* `--log-level=verbo`
+* `--log-level=debug`
+* `--log-level=info`
+* `--log-level=warn`
+* `--log-level=error`
+* `--log-level=fatal`
+* `--log-level=off`
