+# go-http-server
+
+A minimal TCP-based HTTP server in Go for learning and experimentation. It demonstrates manual request-line and header parsing and simple connection handling.
+
+Requires
+- Go 1.26 or newer.
+
+Quick start
+1. Build
+   - cd into the project root (the directory that contains `go-http-server`) and run:
+     ```
+     cd go-http-server
+     go build -o go-http-server
+     ```
+2. Run
+   - Start the server:
+     ```
+     ./go-http-server
+     ```
+   - Or during development:
+     ```
+     go run .
+     ```
+
+Testing
+- Run unit tests:
+  ```
+  cd go-http-server
+  go test ./...
+  ```
+
+What’s in the repo
+- `main.go` — listener and connection lifecycle.
+- `readheaders.go` — `readHeaders` and `parseRequestLine` logic; returns a `Headers` struct.
+- `response_helper` — helpers for writing responses.
+- `config` — runtime configuration (listen address, profiling toggle).
+
+Notes
+- The parser expects a request-line with exactly three tokens: `METHOD URI PROTO`.
+- Header lines without a colon are ignored; values are trimmed.
+- The server supports simple keep-alive behavior when the `Connection: keep-alive` header is present.
+
+Contributing
+- Open issues or PRs. Add tests for parsing or new behavior and run `go test ./...` before submitting.
