-## v2 Status
-
-httpx v1 has been tagged and is now frozen. The `main` branch is v2, which includes intentional breaking changes to improve API clarity and ergonomics (for example, request helpers return `(T, error)`).
-
 ## Why httpx
 
+- Developer-first ergonomics: fast to read, fast to write, predictable to use.
+- Reliability by default: sensible timeouts, safe error handling, resilient retries.
 - Typed, zero-ceremony requests with generics.
 - Opinionated defaults (timeouts, result handling, safe error mapping).
 - Built on req, with full escape hatches via `Client.Req()` and `Client.Raw()`.

-## v2 Error Handling
+All request helpers return `(T, error)`. The low-level escape hatch `Do` returns `(T, *req.Response, error)` when you need raw access.
+
+## Core Surface (use these first)
 
-httpx v2 returns errors as the second return value from request helpers.
+- Requests: `Get / Post / Put / Patch / Delete` (+ `*Ctx`)
+- Composition: `Query`, `Path`, `Header`, `JSON`
+- Client defaults: `New(...)` with BaseURL, auth, timeouts
+- Resiliency: `Retry*`
+- Debug: `Dump`
+- Power-user: `Req` / `Raw` escape hatch
+
+## Most Common Tasks
+
+Brevity-first, idiomatic patterns. Handle errors; dump what matters.
+
+Singular helpers (`Query`, `Path`, `Header`) set one value; plural helpers (`Queries`, `Paths`, `Headers`) set many at once.
