+GLib ConnMan interface library
+----------------------------
+Derived from AGL network binding source at
+[https://git.automotivelinux.org/apps/agl-service-network/]
+
+Source refactoring from the binding (not necessarily exhaustive):
+* network-api.c -> api.c, call_work.c
+* network-connman.c -> connman-call.c
+* network-common.h -> common.h, connman-call.h, call_work.h
+* network-util.c -> mostly redundant, required things moved to api.c, connman-call.c
+
+Copyright dates in files reflect their original creation dates and include
+revisions made in agl-service-network before December 2021.
+
+Building
+--------
+The build requirements are:
+* glib 2.0 headers and libraries (from e.g. glib2-devel on Fedora or CentOS,
+ libglib2.0-dev on Debian or Ubuntu).
+* meson
+
+To build:
+```
+meson build/
+ninja -C build/
+```
+
+Usage Notes
+-----------
+* Users only need include `connman-glib.h` and link to the library.
+* API calls generally return a gboolean, with `FALSE` indicating failure.
+* `connman_init` must be called before any other API calls except
+ `connman_set_log_level` or one of the callback registration functions
+ (e.g. `connman_add_manager_event_callback`).
+* A return code of `TRUE` from `connman_init` indicates D-Bus connection to
+ **ConnMan** has succeeded.
+* Callbacks may be registered after calling `connman_init`, but note that there
+ is a possibility that registration calls may briefly block if they occur
+ during processing of an associated event.
+* It is advised that only one primary user of the library enable agent support
+ to avoid conflicts.
+
+Contributing
+------------
+Questions can be sent to the agl-dev-community mailing list at
+<https://lists.automotivelinux.org/g/agl-dev-community>.
+
+Bugs can be filed on the AGL JIRA instance at <https://jira.automotivelinux.org>.
+
+Source contributions need to go through the AGL Gerrit instance, see
+<https://wiki.automotivelinux.org/agl-distro/contributing>.
