+Roles contain recipes:
+
+```
+$ knife role list
+```
+
+All the recipes that are in that role
+
+```
+$ knife role show <role_name>
+```
+
+To see the nodes:
+
+```
+$ knife node list
+$ knife node show <node_name>
+```
+
+To register a brand new machine with chef
+
+```
+$ knife bootstrap
+```
+This will SSH into the machine, download chef package, install chef to `/opt`, and get it running and registered with the chef server, see `~/.chef/knife.rb`,
+
+
+Before adding/pushing a change in chef
+
+```
+$ knife spork role from file roles/key.json
+$ knife spork omni logstash --remote
+```
+
+when logstash version:
+
+```
+$ knife spork bump logstash
+```

+
+
+1. create a key (choose RSA with 4096):
+
+```
+gpg --full-generate-key
+```
+
+<br>
+
+2. share the public key with:
+```
+gpg --armor --export > public-key.asc
+```
+
+<br>
+
+3. upload to some keyservers, such as ubuntu or MIT:
+```
+gpg --send-keys --keyserver keyserver.ubuntu.com KEYID
+gpg --keyserver hkp://pgp.mit.edu --send-key KEYID
+```
+
+<br>
+
+4. backup the private key:
+```
+gpg --export-secret-keys --armor KEYID > priv.asc
+```
+
+<br>
+
+5. list your keys:
+```
+gpg --list-keys
+gpg --list-secret-keys
+```
+
+<br>
+
+6. clean up if needed:
+```
+gpg --delete-secret-key KEYID
+gpg --delete-key KEYID
+```
+
+<br>
+
+7. finally, you should upload your key into official servers such as **[ubuntu](https://keyserver.ubuntu.com/)** or **[mit](https://pgp.mit.edu/)**.
