+------
+Trusted Services implements the `PSA Certified APIs`_. Libpsa encapsulates the service client implementations
+which implement this API. Linux uuser-space applications can use libpsa to easily access the PSA services
+implemented by the project. Libpsa depends on libts for RPC and service discovery services.

+Build and integration examples
+..............................
+
+Build as shared library::
+
+  cmake -S ./trusted-services/deployments/libpsa/linux-pc/ -B ./build
+  make -C build && make -C build install
+
+.. warning::
+    Building as static library is not yet supported.
+
+To integrate the library libts shall also be integrated. To achieve this add the listed
+lines to the application's cmake files::
+
+  find_package(libpsa "1.0.0" REQUIRED PATHS "<install path>")
+  find_package(libts "2.0.0" REQUIRED PATHS "<install path>")
+  target_link_libraries(ts-demo PRIVATE libpsa::psa)
+
+Initialization
+..............
+
+Before calling any function from libpsa the proper part of the library has to be initialized.
+Before exiting the application (or when PSA services are no longer needed) the initialized
+parts must be deinitialized. To access the library **libpsa.h** must be included::
+
+   psa_status_t libpsa_init_crypto_context(const char *service_name);
+   void libpsa_deinit_crypto_context(void);
+
+   psa_status_t libpsa_init_attestation_context(const char *service_name);
+   void libpsa_deinit_attestation_context(void);
+
+   psa_status_t libpsa_init_its_context(const char *service_name);
+   void libpsa_deinit_its_context(void);
+
+   psa_status_t libpsa_init_ps_context(const char *service_name);
+   void libpsa_deinit_ps_context(void);
+
+The example below initializes and then deinitializes crypto::
+
+    psa_status_t psa_status = libpsa_init_crypto_context("sn:trustedfirmware.org:crypto:0");
+    if (psa_status) {
+        printf("libpsa_init_crypto_context failed: %d\n", psa_status);
+        return PSA_ERROR_GENERIC_ERROR;
+    }
+
+    libpsa_deinit_crypto_context();
+
+Known issues and Limitations
+............................
+
+| The library is single client.
+| The library is not thread safe.
+| Only linux user-space is supported currently.
