+# Publish 
+
+Application for publishing packages to the gitea package server.
+
+Hardcoded my credentials and URLS's. It's a kinda note for myself but if others can learn from it, it's fine by me. 
+
+I've copied this to my `/usr/local/bin/` and can just execute publish [filename] where ever i want. 
+
+## Usage
+Will overwrite version 1.0.0 from the server, else will create a new one with version 1.0.0.
+```
+publish [filename]
+```
+Or with version parameter:
+```
+publish [filename] --version=1.33.7 
+```
