+ * @defgroup cl Client Library
+ * @{
+ *
+ * @brief Provides the public API towards applications using sysrepo to store
+ * their configuration data, or towards management agents.
+ *
+ * Communicates with Sysrepo Engine (@ref cm), which is running either inside
+ * of dedicated sysrepo daemon, or within this library if daemon is not alive.
+ *
+ * Access to the sysrepo datastore is connection- and session- oriented. Before
+ * calling any data access/manipulation API, one needs to connect to the datastore
+ * via ::sr_connect and open a session via ::sr_session_start. One connection
+ * can serve multiple sessions.
+ *
+ * Each data access/manipulation request call is blocking - blocks the connection
+ * until the response from Sysrepo Engine comes, or until an error occurs. It is
+ * safe to call multiple requests on the same session (or different session that
+ * belongs to the same connection) from multiple threads at the same time,
+ * however it is not effective, since each call is blocked until previous one
+ * finishes. If you need fast multi-threaded access to sysrepo, use a dedicated
+ * connection for each thread.
+ *
+ * @see
+ * See @ref main_page "Sysrepo Introduction" for details about sysrepo architecture.
+ * @see
+ * @ref xp_page "XPath Addressing" is used for node identification in data-related calls.
