+                 wolfProvider Installation Notes
+============================================================
+
+wolfProvider is installed in replace-default mode with a 
+patched version of OpenSSL that uses wolfProvider as the 
+crypto backend. wolfProvider will appear as the 'default' 
+provider.
+
+No other conf file modifications or environment variables 
+are required.
+
+To verify installation, run:
+  openssl version
+  openssl list -providers
+
+wolfProvider configuration file installed at:
+  /etc/ssl/openssl.cnf.d/wolfprovider.conf
+

+============================================================
+                 wolfProvider Installation Notes
+============================================================
+
+To use wolfProvider with OpenSSL, choose ONE of the options
+below depending on your use case.
+
+  1) System-wide enable:
+
+     Add the following line to your /etc/ssl/openssl.cnf:
+
+         .include /etc/ssl/openssl.cnf.d/wolfprovider.conf
+
+     This makes wolfProvider available to all applications 
+     that utilize the standard system openssl configuration.
+
+
+  2) Per-command enable (no system-wide changes)
+
+     Set OPENSSL_CONF when running a program:
+
+         OPENSSL_CONF=/etc/ssl/openssl.cnf.d/wolfprovider.conf \
+             <command>
+
+     This enables use of wolfProvider whenever the
+     environment variable is set for the current shell.
+
+
+  3) Application-level integration (for developers)
+
+     In your application, you can create a dedicated OpenSSL
+     library context and explicitly load wolfProvider, e.g.:
+
+         OSSL_LIB_CTX *wpLibCtx = OSSL_LIB_CTX_new();
+         OSSL_PROVIDER *wpProv = OSSL_PROVIDER_load(wpLibCtx, "wolfprovider");
+         /* Use wpLibCtx with EVP, etc. */
+         EVP_function(wpLibCtx, ...);
+         OSSL_PROVIDER_unload(wpProv);
+         OSSL_LIB_CTX_free(wpLibCtx);
+
+     This keeps wolfProvider usage scoped to specific code paths
+     without requiring any system-wide configuration changes.
+
+To verify installation and configuration, run:
+  openssl version
+  openssl list -providers
+
+wolfProvider configuration file installed at:
+  /etc/ssl/openssl.cnf.d/wolfprovider.conf
+
+============================================================

+# Search for the openssl.cnf file in /usr, /lib and /etc
