+Background
+==========
+We implemented Clixon since we needed a generic configuration tool in
+several projects, including
+[KTH](http://www.csc.kth.se/~olofh/10G_OSR). Most of these projects
+were for embedded network and measuring-probe devices. We started with
+something called Clicon which was based on a key-value specification
+and data-store. But as time passed new standards evaolved and we
+started adapting it to XML, Yang and netconf. Finally we made Clixon
+where the legacy key specification has been replaced completely by
+YANG and using XML as configuration data. This means that legacy
+Clicon applications do not run on Clixon.
+
+SDK
+===
+
+<img src="doc/clixon_example_sdk.png" alt="clixon sdk" style="width: 200px;"/>
+
+The figure shows the SDK runtime of Clixon.
+
+YANG and XML is at the heart of Clixon.  Yang modules are used as a
+specification for handling XML configuration data. The spec is also
+used to generate an interactive CLI client as well as provide
+[Netconf](apps/netconf/README.md) and
+[Restconf](apps/restconf/README.md) clients.
+
+The [YANG RFC 6020](https://www.rfc-editor.org/rfc/rfc6020.txt) is implemented with the following exceptions:
+- object-references
+- if-feature
+- unique
+- rpc

+# Clixon datastore
+
+The Clixon datastore is a stand-alone XML based datastore. The idea is
+to be able to use different datastores backends with the same
+API. There is currently a key-value plugin based on qdbm and a plain
+text-file datastore.
+
+The datastore is primarily designed to be used by Clixon but can be used
+separately.  
+
+A datastore is a dynamic plugin that is loaded at runtime with a
+well-defined API. This means it is possible to create your own
+datastore and plug it in a Clixon backend at runtime. 
+
+### The functional API
+```
+int xmldb_plugin_load(clicon_handle h, char *filename);
+int xmldb_plugin_unload(clicon_handle h);
+int xmldb_connect(clicon_handle h);
+int xmldb_disconnect(clicon_handle h);
+int xmldb_getopt(clicon_handle h, char *optname, void **value);
+int xmldb_setopt(clicon_handle h, char *optname, void *value);
+int xmldb_get(clicon_handle h, char *db, char *xpath,
+	      cxobj **xtop, cxobj ***xvec, size_t *xlen);
+int xmldb_put(clicon_handle h, char *db, enum operation_type op, 
+	      char *api_path,  cxobj *xt);
+int xmldb_copy(clicon_handle h, char *from, char *to);
+int xmldb_lock(clicon_handle h, char *db, int pid);
+int xmldb_unlock(clicon_handle h, char *db);
+int xmldb_unlock_all(clicon_handle h, int pid);
+int xmldb_islocked(clicon_handle h, char *db);
+int xmldb_exists(clicon_handle h, char *db);
+int xmldb_delete(clicon_handle h, char *db);
+int xmldb_create(clicon_handle h, char *db);
+```
+
+### Using the API
+
+To use the API, a client needs the following:
+- A clicon handle. 
+- A datastore plugin, such as a text.so or keyvalue.so. These are normally built and installed at Clixon make.
+- A directory where to store databases
+- A yang specification. This needs to be parsed using the Clixon yang_parse() method.
+
+A client calling the API needs to: 
+1. Load a plugin and 
+2. Connect to a datastore. 
+You can connect to several datastores, even concurrently,
+but in practice in Clixon, you connect to a single store. 
+
+After connecting to a datastore, you can create and modify databases
+within the datastore, and set and get options of the datastore itself.
+
+When done, you disconnect from the datastore and unload the plugin.
+
+Within a datastore, the following four databases may exist:
+- running
+- candidate
+- startup
+- tmp
+
+Initially, a database does not exist but is created by
+xmldb_create(). It is deleted by xmldb_delete(). You may check for
+existence with xmldb_exists(). You need to create a database before
+you can perform any data access on it.
+
+You may lock a database for exclusive modification according to
+Netconf semantics. You may also unlock a single dabase, unlock all frm
+a specific session.
+
+You can read a database with xmldb_get() and modify a database with
+xmldb_put(), and xmldb_copy().
+
+A typical datastore session can be as follows, see the source code of
+[datastore_client.c](datastore_client.c) for a more elaborate example.
+
+```
+  h = clicon_handle_init();
+  xmldb_plugin_load(h, plugin);
+  xmldb_connect(h);
+  xmldb_setopt(h, "dbdir", dbdir);
+  xmldb_setopt(h, "yangspec", yspec);
+  /* From here databases in the datastore may be accessed */
+  xmldb_create(h, "candidate");
+  xmldb_copy(h, "running", "candidate");
+  xmldb_lock(h, "candidate", 7878);
+  xmldb_put(h, "candidate", OP_CREATE, "/interfaces/interface=eth0", xml);
+  xmldb_unlock(h, "candidate");
+  xmldb_get(h, "candidate", "/", &xml, &xvec, &xlen);
+  xmldb_disconnect(h)
+  xmdlb_plugin_unload(h);
+```

-Frequently Asked Questions - CliXon
+# Clixon FAQ
-===================================
 
-Q: What is CliXon?
+## What is Clixon?
-------------------
-CliXon is a configuration management tool including CLI generation,
-Yang parser, netconf interface and an embedded databases.
 
-Q: Why should you use CliXon?
+Clixon is a configuration management tool including a generated CLI ,
------------------------------
+Yang parser, netconf and restconf interface and an embedded databases.
-If you want an easy-to-use config frontend based on yang with an open-source license.
-Typically for embedded devices requiring a config interface such as routers and switches.
 
-Q: What license is available?
+## Why should I use Clixon?
------------------------------
-The basic license is open-source, GPLv3. Contact authors for commercial license.
 
-Q: Is CliXon extendible?
+If you want an easy-to-use configuration frontend based on yang with an
-------------------------
+open-source license.  Typically for embedded devices requiring a
-Yes. All application semantics is defined in plugins with well-defined APIs. There are currently three types of plugins: for CLI, for Netconf and for the backend. 
+config interface such as routers and switches. 
 
-Q: Which language is CliXon implemented in?
+## What license is available?
--------------------------------------------
+CLIXON is dual license. Either Apache License, Version 2.0 or GNU
-CliXon is written in C. The plugins are written in C. The CLI
+General Public License Version 2. 
+
+## Is Clixon extendible?
+Yes. All application semantics is defined in plugins with well-defined
+APIs. There are currently plugins for: CLI, Netconf,  Restconf, the datastore and the backend.
+
+## Which programming language is used?
+Clixon is written in C. The plugins are written in C. The CLI
 specification uses cligen (http://cligen.se)
 
 There is a project for writing plugins in Python. It is reasonable
 simple to spawn an external script from a backend.
 
-Q: Is CliXon different from Clicon?
+## How to best understand Clixon?
------------------------------------
+Run the ietf yang routing example, in the example directory.
-CliXon is a fork of Clicon focussing on Yang specification and XML
-database.  The yang support in clicon was grown out of a key-based
-scheme that became more and more complex since it had to translate
-between many different formats. CliXon uses only XML internally.
 
-The commit transaction mechanism has been simplified too. But CliXon
+## How do you build and install Clixon (and the example)?
-is not backward compliant with key-based Clixon applications, such as
+Clixon: 
-Rost.
+```
-
-Q: How to best understand CliXon?
----------------------------------
-Run the ietf yang routing example. It is used in many of the answers below.
-
-Q: How do you build and install CliXon (and the example)?
----------------------------------------------------------
-CliXon: 
 	./configure; 
 	make; 
 	sudo make install; 
 	sudo make install-include
-
+```
 The example: 
+```
 	 cd example; 
 	 make; 
 	 sudo make install
+```
 
-Q: What about reference documentation?
+## What about reference documentation?
---------------------------------------
+Clixon uses Doxygen for reference documentation.
-CliXon uses Doxygen for reference documentation.
 Build using 'make doc' and aim your browser at doc/html/index.html or
 use the web resource: http://clicon.org/ref/index.html

-Q: How do you change the example?
----------------------------------
-- routing.conf.local - Override default settings
-- The yang specifications - This is the central part. It changes the XML, database and the config cli.
-- routing_cli.cli - Change the fixed part of the CLI commands 
-- routing_cli.c - Cli C-commands are placed here.
-- routing_backend.c - Commit and validate functions.
-- routing_netconf.c - Modify semantics of netconf commands.

-Q: How do you check what is in a database?
-------------------------------------------
-Use clixon_dbctrl. The name of the running or candidate databases are found in the
-configuration file.
-Example:
-	> clixon_dbctrl -d /usr/local/var/routing/candidate_db / -p
-	/interfaces/interface/eth0/ipv4 
-	/interfaces/interface/eth0/type bgp
-	/interfaces/interface/eth0 
-	/interfaces/interface/eth0/name eth0
-Each line corresponds to a database entry (node in an XML tree). 
-If the node is a leaf, the value appears as the second entry ('bgp' and 'eth0').
-
-Q: What is validate and commit?
--------------------------------
 Clixon follows netconf in its validate and commit semantics.

 'validated' for consistency and then 'committed' to the 'running'

-Q: How do you write a CLI callback function?
---------------------------------------------
-(1) You add an entry in routing_cli.cli
