 # gitea-actions
 
+## Setup
+
+For these actions to work properly one needs a bot account for the token. So, once the bot account is created, generate a token for it with `repository:write` and `package:write` permissions. However that's not enough, even making the bot a repository collaborator is not enough. The bot needs to have permissions on the organization level.
+
+The recommended way is to create a team in the organization that has access to all repositories and set `Releases:Write` and `Packages:Write` permissions and `Read` for all the rest (yet, strictly speaking that's not necessary) and add the bot to the team.
+
+The workflow (or jobs individually) needs to define an env variable `ACTI_BOT_TOKEN` with the bots token (as secrets do not automatically propagate into composite action context, at least it didn't work while testing).
+
+## Publish
+
+Publishes a `generic` package to current Gitea instance. Example:
+
+```yaml
+  - uses: https://source.vague.tech/open-vague/ci-actions/publish@feature/1-publish
+    with:
+      file: some-content.json
+      package: the-package
+      version: master
+      force: true
+```
+
+* `file` - path to the file to upload (used as uploaded file name within the package)
+* `package` - the package name
+* `version` - the package version, need to be unique (unless force flag is set)
+* `force` - false by default; if set **deletes the whole version** of the package (all files) and then publishes instead with the same version
