 ### Tag Input Parsing

 Uses `csv-parse/sync` to handle both CSV and newline-delimited formats. Supports
-per-tag ref overrides: `v1:main` tags `v1` to `main` branch.
+per-tag ref and annotation overrides using the format `tag:ref:annotation`:
+
+- `tag` — Use default `ref` and `annotation` inputs
+- `tag:ref` — Override ref for this tag (e.g., `v1:main` tags `v1` to `main`)
+- `tag:ref:annotation` — Override both ref and annotation
+- `tag::annotation` — Override annotation only (empty ref uses default)
+
+Annotations can contain colons; everything after the second colon is treated as
+the annotation text. Per-tag values override the global `ref` and `annotation`
+inputs.
+
+### Tag Derivation
+
+The `derive_from` input allows automatic generation of tags from a semver
+version string. Uses Handlebars templates with these placeholders:
+
+- `{{prefix}}`: "v" or "V" if input had prefix, empty otherwise
+- `{{major}}`, `{{minor}}`, `{{patch}}`: Version numbers
+- `{{prerelease}}`, `{{build}}`: Optional semver components
+- `{{version}}`: Full version without prefix
+
+Default template `{{prefix}}{{major}},{{prefix}}{{major}}.{{minor}}` generates
+major and minor tags (e.g., `v1.2.3` → `v1`, `v1.2`). Supports Handlebars
+conditionals like `{{#if prerelease}}...{{/if}}`.

-5. Set outputs with created/updated tag lists ([main.ts](src/main.ts))
+2. Plan all tag operations ([tags.ts](src/tags.ts):planTagOperations):
+   - Parse `tag:ref:annotation` syntax and extract per-tag refs/annotations
+   - Pre-resolve all unique refs to SHAs in parallel (optimization)
+   - For each tag, check existence and determine operation:
+     - If exists + fail mode: Fail action immediately
+     - If exists + skip mode: Plan skip
+     - If exists + update mode: Plan update if SHA or annotation differs

+### Tag Input Syntax
+
+The `tags` input accepts a comma or newline-delimited list of tags. Each tag
+specification supports optional per-tag ref and annotation overrides using the
+format:
+
+```
+tag[:ref[:annotation]]
+```
+
+| Format               | Description                                     |
+| -------------------- | ----------------------------------------------- |
+| `tag`                | Tag using default `ref` and `annotation` inputs |
+| `tag:ref`            | Tag using specified ref, default annotation     |
+| `tag:ref:annotation` | Tag using specified ref and annotation          |
+| `tag::annotation`    | Tag using default ref with specified annotation |
+
+**Per-tag refs** allow different tags to point to different commits:
+
+```yaml
+- uses: jimeh/update-tags-action@v2
+  with:
+    tags: |
+      v1:main
+      v2:develop
+```
+
+**Per-tag annotations** allow different annotation messages for each tag:
+
+```yaml
+- uses: jimeh/update-tags-action@v2
+  with:
+    tags: |
+      v1:main:Latest v1.x release
+      v1.2:main:Latest v1.2.x release
+```
+
+Use `tag::annotation` to specify an annotation while using the default ref:
+
+```yaml
+- uses: jimeh/update-tags-action@v2
+  with:
+    tags: |
+      v1::This is the v1 tag annotation
+      v1.2::This is the v1.2 tag annotation
+```
+
+Per-tag values override the global `ref` and `annotation` inputs:
+
+```yaml
+- uses: jimeh/update-tags-action@v2
+  with:
+    tags: |
+      v1:main:Custom annotation for v1
+      v2
+    ref: develop
+    annotation: Default annotation for tags without per-tag override
+    # v1 -> main with "Custom annotation for v1"
+    # v2 -> develop with "Default annotation..."
+```
+
+Annotations can contain colons (everything after the second colon is the
+annotation):
+
+```yaml
+- uses: jimeh/update-tags-action@v2
+  with:
+    tags: |
+      v1:main:Release: version 1.0.0
+    # Annotation will be "Release: version 1.0.0"
+```
+
+### Derive Template Syntax
+
+The `derive_from_template` input uses [Handlebars](https://handlebarsjs.com/)
+for template rendering. Splitting the template into separate tags by comma or
+newline is done after the template is rendered.
+
+Available placeholders:
+
+| Placeholder      | Description                                           |
+| ---------------- | ----------------------------------------------------- |
+| `{{prefix}}`     | `v` or `V` if input had a prefix, empty otherwise     |
+| `{{major}}`      | Major version number                                  |
+| `{{minor}}`      | Minor version number                                  |
+| `{{patch}}`      | Patch version number                                  |
+| `{{prerelease}}` | Prerelease identifier (e.g., `beta.1`), empty if none |
+| `{{build}}`      | Build metadata (e.g., `build.123`), empty if none     |
+| `{{version}}`    | Full version string without prefix                    |
+
+#### Conditional Sections
+
+Use Handlebars `{{#if}}` blocks to include content only when a variable has a
+value. This is useful for optional components like prerelease or build metadata:
+
+```yaml
+- uses: jimeh/update-tags-action@v2
+  with:
+    derive_from: v1.2.3-beta.1
+    derive_from_template: |
+      {{prefix}}{{major}}{{#if prerelease}}-{{prerelease}}{{/if}}
+    # Creates tag: v1-beta.1
+```
+
+For a stable release without prerelease:
+
+```yaml
+- uses: jimeh/update-tags-action@v2
+  with:
+    derive_from: v1.2.3
+    derive_from_template: |
+      {{prefix}}{{major}}{{#if prerelease}}-{{prerelease}}{{/if}}
+    # Creates tag: v1 (prerelease section omitted)
+```
+
+You can also use `{{#unless}}` for inverse logic:
+
+```yaml
+- uses: jimeh/update-tags-action@v2
+  with:
+    derive_from: v1.2.3
+    derive_from_template: |
+      {{prefix}}{{major}}{{#unless prerelease}}-stable{{/unless}}
+    # Creates tag: v1-stable (only for non-prerelease versions)
+```
