+# Contributing to sed
+
+Hi! Welcome to uutils/sed, and thanks for wanting to contribute!
+
+This project follows the shared conventions of the [uutils](https://github.com/uutils)
+organization. Before opening a pull request, please read:
+
+- Our **[Review Guidelines](https://uutils.github.io/reviews/)** — what we expect
+  from a pull request and how reviews are carried out.
+- Our community's [CODE_OF_CONDUCT.md](./CODE_OF_CONDUCT.md), if present.
+
+Finally, feel free to join our [Discord](https://discord.gg/wQVJbvJ)!
+
+> [!WARNING]
+> uutils is original code and cannot contain any code from GNU or other
+> strongly-licensed (GPL/LGPL) implementations. We **cannot** accept changes
+> based on the GNU source code, and you **must not link** to it either. You may
+> look at permissively-licensed implementations (MIT/BSD) and read the GNU
+> *manuals* — never the GNU *source*.
+
+## In short
+
+- Discuss non-trivial changes in an issue **before** writing the code.
+- Keep pull requests **small, self-contained, and descriptively titled**
+  (e.g. `sed: fix ...`).
+- Make sure CI passes: tests are green, `rustfmt` is satisfied, and there are
+  no `clippy` warnings.
+- Add tests for new behavior; don't let coverage regress.
+- Write small, atomic commits annotated with the component you touched.
+
+See the [Review Guidelines](https://uutils.github.io/reviews/) for the full
+details.

+## Testing
+
+### GNU sed Compatibility Testing
+
+Test compatibility against GNU sed by running the upstream testsuite shell scripts
+with a lightweight gnulib test-framework shim:
+
+```bash
+# Clone GNU sed testsuite (one time setup)
+git clone https://github.com/mirror/sed.git ../gnu.sed
+
+# Run compatibility tests
+./util/run-gnu-testsuite.sh
+
+# Verbose mode shows failure details
+./util/run-gnu-testsuite.sh -v
+
+# Generate JSON results for CI
+./util/run-gnu-testsuite.sh --json-output results.json
+```
+
+The harness executes each `.sh` test from the GNU sed testsuite directly, injecting
+our Rust sed binary via `PATH` and providing shim implementations of the gnulib test
+framework functions (`compare_`, `returns_`, `skip_`, etc.).
+
+### Unit Tests
+
+```bash
+cargo test
+```

 ## Extensions and incompatibilities
 ### Supported GNU extensions
 * Command-line arguments can be specified in long (`--`) form.
 * Spaces can precede a regular expression modifier.
 * `I` can be used in as a synonym for the `i` (case insensitive) substitution
   flag.
+* `M` and `m` substitution flags allow multi-line matching.
 * In addition to `\n`, other escape sequences (octal, hex, C) are supported
   in the strings of the `y` command.
   Under POSIX these yield undefined behavior.
 * The `a`, `c`, and `i` commands do not require an initial backslash,
   allow text to appear on the same line, and support escape sequences
   in the specified text.
+* The `a`, `i`, `=`, `l`, `q` and `r` commands support address range as an extension to POSIX.
 * The substitution command replacement group `\0` is a synonym for &.
 * A `Q` command (optionally followed by an exit code) quits immediately.
 * The `q` command can be optionally followed by an exit code.
 * The `l` command can be optionally followed by the output width.
-* The `--follow-symlinks` flag for in-place editing.
+* The `--follow-symlinks` option for in-place editing.
+* The `--sandbox` option that limits potentially destructive commands.
+* Address 0 can be used to specify an address range that is already
+  active on line 1 and can finish with the specified regular expression.
+* Address steps can be specified in the form of start~step and start,~step
+  ranges.
+* Address 0 can be used in the `r` command to prepend a file.
 
 ### Supported BSD and GNU extensions
 * The second address in a range can be specified as a relative address with +N.

 ### Incompatibilities
-* The input is assumed to be valid UTF-8 (this includes 7-bit ASCII).
-  If the input is in another code page, consider converting it through UTF-8
-  in order to avoid errors on invalid UTF-8 sequences and for the correct
-  handling of regular expressions.
-  This _sed_ program can also handle arbitrary byte sequences if no part of the
-  input is treated as string.
+* Similarly to GNU _sed_, input is processed as raw bytes or as valid UTF-8
+  (this includes 7-bit ASCII) based on the locale as specified by the
+  `LC_ALL`, `LC_CTYPE`, and `LANG` environment variables,
+  with the default being byte processing.
+  However, in contrast with GNU _sed_, other locales (e.g. ISO-8859-1)
+  are not supported. If the input is in another code page or encoding
+  and requires locale-specific processing (e.g. ignore/map case,
+  character classes), consider converting it through UTF-8 to ensure
+  the correct handling of locale-specific regular expressions.
+  This _sed_ program can also handle arbitrary byte sequences
+  if no part of the input requires treating it as a Rust String.
+* Back-references aren't supported when input is processed as bytes
+  (`LC_ALL=C`).
 * The command will report an error and fail if duplicate labels are found
   in the script.
   This matches the BSD behavior. The GNU version accepts duplicate labels.
