+# ZeroName
+
+Zeroname plugin to connect Namecoin and register all the .bit domain name.
+
+## Start
+
+You can create your own Zeroname.
+
+### Namecoin node
+
+You need to run a namecoin node.
+
+[Namecoin](https://namecoin.org/download/)
+
+You will need to start it as a RPC server.
+
+Example of `~/.namecoin/namecoin.conf` minimal setup:
+```
+daemon=1
+rpcuser=your-name
+rpcpassword=your-password
+rpcport=8336
+server=1
+txindex=1
+```
+
+Don't forget to change the `rpcuser` value and `rpcpassword` value!
+
+You can start your node : `./namecoind`
+
+### Update `updater/zeroname_updater.py`
+
+
+You need update lines 117-118 with the correct `rpcuser` and `rpcpassword`.
+```
+    'user': 'PLACEHOLDER',
+    'password': 'PLACEHOLDER',
+```
+
+You will also need to create a site `python zeronet.py createSite` and regitser the info.
+
+In the site you will need to create a file `./data/<your-site>/data/names.json` with this is it:
+```
+{}
+```
+
+### `zeroname_config.json` file
+
+In `~/.namecoin/zeroname_config.json`
+```
+{
+  "lastprocessed": 223910,
+  "zeronet_path": "/root/ZeroNet", # Update with your path
+  "privatekey": "", # Update with your private key of your site
+  "site": "" # Update with the address of your site
+}
+```
+
+### Run updater
+
+You can now run the script : `updater/zeroname_updater.py` and wait until it is fully sync (it might take a while).
