 ## [Unreleased]
 
+## [0.10.6] - 2025-09-21

+### Fixed
+- Added a crate-local README for `masterror-derive` so `cargo publish` passes
+  when crates.io validates the `readme` manifest key.
+
+### Changed
+- Bumped `masterror-derive` to `0.6.2` to capture the packaging fix.
+
+### Documentation
+- Documented the derive macros and supported attributes in
+  `masterror-derive/README.md` for crates.io readers.

+# masterror-derive
+
+Procedural macros that power [`masterror`](https://crates.io/crates/masterror)'s
+`#[derive(Error)]`. The derive generates ergonomic `std::error::Error` and
+`Display` implementations together with seamless integration into
+`masterror`'s domain-centric `AppError` type.
+
+> **Tip:** Depend on the `masterror` crate in application code and import the
+> macros from there (`use masterror::Error;`). This standalone crate is
+> published to make `cargo install`/`cargo package` flows happy and to support
+> advanced macro integrations.
+
+## Quick start
+
+```toml
+[dependencies]
+masterror = "0.10"
+```
+
+```rust
+use masterror::{AppError, Error};
+
+#[derive(Error)]
+#[error(display = "failed to parse payload: {source}")]
+#[app_error(kind = "BadRequest")]
+pub struct PayloadInvalid {
+    #[source]
+    pub source: serde_json::Error,
+}
+
+fn parse(input: &str) -> Result<(), AppError> {
+    serde_json::from_str::<serde_json::Value>(input)
+        .map(|_| ())
+        .map_err(PayloadInvalid::from)
+}
+```
+
+The derive implements `Display`, `std::error::Error`, and conversion glue so
+you can return rich `AppError` values with a single `?`.
+
+## Supported attributes
+
+- `#[error(display = ...)]` – formats the error message using captured fields.
+- `#[source]` / `#[from]` – wires source error propagation and conversion.
+- `#[backtrace]` – exposes an optional captured `Backtrace`.
+- `#[app_error(...)]` – configures how the error maps into `AppError`
+  (kind, HTTP status, telemetry).
+- `#[provide(...)]` – attaches structured telemetry providers that surface
+  typed context (IDs, domains, tenant information) through tracing layers.
+
+See the main [`masterror` README](https://github.com/RAprogramm/masterror/blob/HEAD/README.md) for an end-to-end guide and
+advanced examples covering templated display strings, telemetry providers and
+OpenAPI/schema integrations.
