+### Releasing new versions
+
+The version of a plugin is determined at compile time, automatically populating a `version` field in the [plugin manifest](plugin.json):
+* If the current commit matches a tag, the version will match after stripping any leading `v`, e.g. `1.3.1`.
+* Otherwise, the version will combine the nearest tag with `git rev-parse --short HEAD`, e.g. `1.3.1+d06e53e1`.
+* If there is no version tag, an empty version will be combined with the short hash, e.g. `0.0.0+76081421`.
+
+To disable this behaviour, manually populate and maintain the `version` field.
+
 ## Q&A
 
 ### How do I make a server-only or web app-only plugin?

Subject: [PATCH 07/10] [feat] Implementing new release process (#200)

Streamlining the release process for mattermost-plugins by integrating release and signing pipelines under the delivery platform.

This update automates signing and releasing by simply pushing a semver tag(e.g: v0.0.1) or by using the newly introduced Makefile targets.
```
make patch
make minor
make major
```

For Release Candidades(RC):
```
make patch-rc
make minor-rc
make major-rc
```

+   This will release a minor change.
+
+3. **For Major Release:** Run the following command:
+    ```
+    make major
+    ```
+   This will release a major change.
+
+4. **For Patch Release Candidate (RC):** Run the following command:
+    ```
+    make patch-rc
+    ```
+   This will release a patch release candidate.
+
+5. **For Minor Release Candidate (RC):** Run the following command:

-# Plugin Starter Template [![CircleCI branch](https://img.shields.io/circleci/project/github/mattermost/mattermost-plugin-starter-template/master.svg)](https://circleci.com/gh/mattermost/mattermost-plugin-starter-template)
+# Plugin Starter Template [![CircleCI branch](https://img.shields.io/circleci/project/github/mattermost/mattermost-plugin-attachments-remover/master.svg)](https://circleci.com/gh/mattermost/mattermost-plugin-attachments-remover)
 
-This plugin serves as a starting point for writing a Mattermost plugin. Feel free to base your own plugin off this repository.
+## Features
 
-To learn more about plugins, see [our plugin documentation](https://developers.mattermost.com/extend/plugins/).
-
-This template requires node v16 and npm v8. You can download and install nvm to manage your node versions by following the instructions [here](https://github.com/nvm-sh/nvm). Once you've setup the project simply run `nvm i` within the root folder to use the suggested version of node.
-
-## Getting Started
-Use GitHub's template feature to make a copy of this repository by clicking the "Use this template" button.
-
-Alternatively shallow clone the repository matching your plugin name:
-```
-git clone --depth 1 https://github.com/mattermost/mattermost-plugin-starter-template com.example.my-plugin
-```
-
-Note that this project uses [Go modules](https://github.com/golang/go/wiki/Modules). Be sure to locate the project outside of `$GOPATH`.
-
-Edit the following files:
-1. `plugin.json` with your `id`, `name`, and `description`:
-```json
-{
-    "id": "com.example.my-plugin",
-    "name": "My Plugin",
-    "description": "A plugin to enhance Mattermost."
-}
-```
-
-2. `go.mod` with your Go module path, following the `<hosting-site>/<repository>/<module>` convention:
-```
-module github.com/example/my-plugin
-```
-
-3. `.golangci.yml` with your Go module path:
-```yml
-linters-settings:
-  # [...]
-  goimports:
-    local-prefixes: github.com/example/my-plugin
-```
-
-Build your plugin:
-```
-make
-```
-
-This will produce a single plugin file (with support for multiple architectures) for upload to your Mattermost server:
-
-```
-dist/com.example.my-plugin.tar.gz
-```
+- Allows users and sysadmins to delete attachments from posts via a context menu option
 
 ## Development
 
@@ -161,29 +115,5 @@ To trigger a release, follow these steps:
 
 ## Q&A
 
-### How do I make a server-only or web app-only plugin?
-
-Simply delete the `server` or `webapp` folders and remove the corresponding sections from `plugin.json`. The build scripts will skip the missing portions automatically.
-
-### How do I include assets in the plugin bundle?
-
-Place them into the `assets` directory. To use an asset at runtime, build the path to your asset and open as a regular file:
-
-```go
-bundlePath, err := p.API.GetBundlePath()
-if err != nil {
-    return errors.Wrap(err, "failed to get bundle path")
-}
-
-profileImage, err := ioutil.ReadFile(filepath.Join(bundlePath, "assets", "profile_image.png"))
-if err != nil {
-    return errors.Wrap(err, "failed to read profile image")
-}
-
-if appErr := p.API.SetProfileImage(userID, profileImage); appErr != nil {
-    return errors.Wrap(err, "failed to set profile image")
-}
-```
-
 ### How do I build the plugin with unminified JavaScript?
 Setting the `MM_DEBUG` environment variable will invoke the debug builds. The simplist way to do this is to simply include this variable in your calls to `make` (e.g. `make dist MM_DEBUG=1`).
