 # gnutls-wolfssl
 
-Experimental port of wolfSSL into gnutls
+Experimental port of wolfSSL into GnuTLS. One script builds everything and drops the bits under /opt.
+
+## Quick start
+```
+git clone https://github.com/YOURORG/gnutls-wolfssl.git
+cd gnutls-wolfssl
+# regular build
+./setup.sh
+
+# build with FIPS 140 support
+./setup.sh fips
+```
+On success you get:
+```
+/opt/wolfssl                  wolfSSL
+/opt/gnutls                   GnuTLS built on wolfSSL
+/opt/wolfssl-gnutls-wrapper   runtime shim
+```
+If the loader can’t find the libs, add the path to LD_LIBRARY_PATH (Linux) or DYLD_LIBRARY_PATH (macOS).
+
+## Environment variables
+| var | default | note |
+|-----|---------|------|
+| WOLFSSL_INSTALL | /opt/wolfssl | install prefix |
+| GNUTLS_INSTALL  | /opt/gnutls  | install prefix |
+| GNUTLS_FORCE_FIPS_MODE | – | set at runtime to enforce FIPS |
+
+## Directory layout (after setup.sh has been run)
+```
+setup.sh                       do‑it‑all build script
+rebuild-gnutls.sh              rebuild GnuTLS only

+gnutls/                        upstream clone + branch gnutls-wolfssl
+wolfssl-gnutls-wrapper/        thin shim + tests
+```
+
+## Tests
+```
+cd wolfssl-gnutls-wrapper
+
+# build wrapper
+make
+
+# full suite
+make test
+
+# fast run of the test suite
+make test_fast
+
+# test fips (only if ./setup.sh was run in fips mode)
+make test_fips
+```
+Each test prints ✔️/❌ and a summary.
+
+## Using in your project
+```
+cc app.c \
+  -I/opt/gnutls/include -I/opt/wolfssl/include \
+  -L/opt/gnutls/lib -lgnutls \
+  -L/opt/wolfssl/lib -lwolfssl \
+  -L/opt/wolfssl-gnutls-wrapper/lib -lgnutls-wolfssl-wrapper
+```
+Make sure the wrapper comes after gnutls on the linker line.
+
+## Clean up
+```
+sudo rm -rf /opt/wolfssl /opt/gnutls /opt/wolfssl-gnutls-wrapper
+```
