+# Network Configurations
+
+Network configurations should be of the format:
+```
+SOURCE_URL=<url for packages>
+NETWORK_NAME=<name of network>
+```
+It is recommended that network_name used is the same as the <network_name>.conf.  This will be executed as 
+`source "$DIR/network_configs/<config_file>.conf` to load these variables.
+
+## Usage 
+
+These configurations will be sent to `pull_casper_node_version.sh` as an argument.
+
+The target URL is expected to serve HTTP access to `<url>/<network_name>/<protocol_version>/[bin.tar.gz|config.tar.gz]`
+
+Example:
+`sudo -u casper pull_casper_node_version.sh casper.conf 1_0_0`
+
+With `casper.conf` of:
+```
+SOURCE_URL=genesis.casperlabs.io
+NETWORK_NAME=casper
+```
+
+Will perform:
+```
+curl -JLO genesis.casperlabs.io/casper/1_0_0/bin.tar.gz
+curl -JLO genesis.casperlabs.io/casper/1_0_0/config.tar.gz
+```
+
+`config.tar.gz` is decompressed into `/etc/casper/<protocol_version>`.
+`bin.tar.gz` is decompressed into `/var/lib/casper/<protocol_version>`.
+
+The script will error if protocol versions already exist.
+
+## Packaging
+
+With merges to `master`, `release-*` and `dev` branches in the `casper-node` repo, the artifacts are created in
+`genesis.casperlabs.io/drone/<git_hash>/<protocol version>/[bin.tar.gz|config.tar.gz]`.
+
+You may also pull down the artifacts for a given network and modify to stage a new network.  
+If you want to launch a network with the same software version of `casper`, you could pull down the `bin.tar.gz` and 
+use as is.  However, your `config.tar.gz` would need modified.
+
+```
+mkdir config
+curl -JLO genesis.casperlabs.io/casper/1_0_0/bin.tar.gz
+curl -JLO genesis.casperlabs.io/casper/1_0_0/config.tar.gz
+mv config.tar.gz config_old.tar.gz
+cd config
+tar -xzvf ../config_old.tar.gz
+```
+
+You would need to customize `chainspec.toml` with a new network name and activation_point timestamp.
+You would need to customize `config-example.toml` with new known_addresses.
+
+Once all the configuration changes are done.  Create a new config.tar.gz from within the config directory.
+
+```
+tar -czvf ../config.tar.gz .
+```
+
+Now upload `bin.tar.gz` and `config.tar.gz` to your `<url>/<network>/<protocol_version>` location.
