+# Project Status Registry
+
+Project Status Registry is a small CosmWasm contract that records project milestones and their current review status. It is intended as a simple example of owner-managed records with public queries.
+
+## What It Teaches
+
+- Saving contract configuration with `Item`
+- Saving multiple records with `Map`
+- Restricting write actions to a validated owner
+- Querying a single record or a paginated list of records
+- Emitting useful response attributes from execute messages
+
+## Contract Flow
+
+1. Instantiate the contract with an optional owner. If no owner is supplied, the sender becomes the owner.
+2. The owner adds project records with an id, title, status, and note.
+3. The owner updates a project's status as work moves through review.
+4. Anyone can query a project or list the stored projects.
+
+## Messages
+
+### Instantiate
+
+```rust
+pub struct InstantiateMsg {
+    pub owner: Option<String>,
+}
+```
+
+### Execute
+
+```rust
+pub enum ExecuteMsg {
+    AddProject {
+        id: String,
+        title: String,
+        status: ProjectStatus,
+        note: String,
+    },
+    UpdateStatus {
+        id: String,
+        status: ProjectStatus,
+        note: String,
+    },
+    TransferOwnership {
+        new_owner: String,
+    },
+}
+```
+
+### Query
+
+```rust
+pub enum QueryMsg {
+    Config {},
+    Project { id: String },
+    ListProjects {
+        start_after: Option<String>,
+        limit: Option<u32>,
+    },
+}
+```
+
+## Example Use Cases
+
+- Track open-source grant milestones.
+- Publish a transparent status log for community projects.
+- Keep lightweight on-chain evidence of who last updated a project record.
