+
+In order to publish new version/release of Robocode to the Maven repository you need GPG key.
+
+You can create it using this command:
+
+```shell
+gpg --default-new-key-algo rsa4096 --gen-key
+```
+
+You can export the public key to a file with this command:
+
+```shell
+gpg --export --armor --output public-key.pub
+```
+
+Next you need to upload your public key (is in the .pub file) to this server:
+http://keyserver.ubuntu.com:11371/
+
+Next, you need to export the secret keys to a file that must be located in your home directory:
+
+```shell
+gpg --keyring secring.gpg --export-secret-keys > [user-home-dir]/.gnupg/secring.gpg
+```
+
+Where `[user-home-dir]` is the home directory for your user account.
+
+You can list the secret keys with this command, to read out the last 8 digits of the secret GPG key:
 
 ```shell
-gpg --keyring secring.gpg --export-secret-keys > ~/.gnupg/secring.gpg
 gpg -K
 ```
