+### Feature Request
+Please put [FR] in the issue title: `[FR] Add-on that goes 'ping'`
+
+------------------------------------------------------------
+### Compile Error
+When I compile with `FEATURE_X` I get an error:
+```
+Paste_the_error_text_here
+```
+
+------------------------------------------------------------
+### Bug Report
+- Description: ---
+- Expected behaviour: ---
+- Actual behaviour: ---
+- Steps to reproduce:
+  - Do this
+  - Do that
+
+Attach a ZIP of `Configuration.h` and `Configuration_adv.h` by dropping here.
+
+------------------------------------------------------------
+### Bug Report Tips
+- When troubleshooting, use `M502` followed by `M500` to reset EEPROM to defaults.
+- Use `DEBUG_LEVELING_FEATURE` with `M111 S247` for detailed logging of homing/leveling.
+- Format text with: **bold**, _italic_, `code`.
+- Format C++ with three backticks, plus "cpp":
+```cpp
+void my_function(bool do_it) {
+  // Hold this spot
+}
+```

+   *   G26 Mesh Validation Tool
+   *
+   *   G26 is a Mesh Validation Tool intended to provide support for the Marlin Unified Bed Leveling System.
+   *   In order to fully utilize and benefit from the Marlin Unified Bed Leveling System an accurate Mesh must
+   *   be defined.  G29 is designed to allow the user to quickly validate the correctness of her Mesh.  It will
+   *   first heat the bed and nozzle. It will then print lines and circles along the Mesh Cell boundaries and
+   *   the intersections of those lines (respectively).
+   *
+   *   This action allows the user to immediately see where the Mesh is properly defined and where it needs to
+   *   be edited.  The command will generate the Mesh lines closest to the nozzle's starting position.  Alternatively
+   *   the user can specify the X and Y position of interest with command parameters.  This allows the user to
+   *   focus on a particular area of the Mesh where attention is needed.
+   *
+   *   B #  Bed         Set the Bed Temperature.  If not specified, a default of 60 C. will be assumed.
+   *
+   *   C    Current     When searching for Mesh Intersection points to draw, use the current nozzle location
+   *                    as the base for any distance comparison.
+   *
+   *   D    Disable     Disable the Unified Bed Leveling System.  In the normal case the user is invoking this
+   *                    command to see how well a Mesh as been adjusted to match a print surface.  In order to do
+   *                    this the Unified Bed Leveling System is turned on by the G26 command.  The D parameter
+   *                    alters the command's normal behaviour and disables the Unified Bed Leveling System even if
+   *                    it is on.
+   *
+   *   H #  Hotend      Set the Nozzle Temperature.  If not specified, a default of 205 C. will be assumed.
+   *
+   *   F #  Filament    Used to specify the diameter of the filament being used.  If not specified
+   *                    1.75mm filament is assumed.  If you are not getting acceptable results by using the
+   *                    'correct' numbers, you can scale this number up or down a little bit to change the amount
+   *                    of filament that is being extruded during the printing of the various lines on the bed.
+   *
+   *   K    Keep-On     Keep the heaters turned on at the end of the command.
+   *
+   *   L #  Layer       Layer height.  (Height of nozzle above bed)  If not specified .20mm will be used.
+   *
+   *   O #  Ooooze      How much your nozzle will Ooooze filament while getting in position to print.  This
+   *                    is over kill, but using this parameter will let you get the very first 'circle' perfect
+   *                    so you have a trophy to peel off of the bed and hang up to show how perfectly you have your
+   *                    Mesh calibrated.  If not specified, a filament length of .3mm is assumed.
+   *
+   *   P #  Prime       Prime the nozzle with specified length of filament.  If this parameter is not
+   *                    given, no prime action will take place.  If the parameter specifies an amount, that much
+   *                    will be purged before continuing.  If no amount is specified the command will start
+   *                    purging filament until the user provides an LCD Click and then it will continue with
+   *                    printing the Mesh.  You can carefully remove the spent filament with a needle nose
+   *                    pliers while holding the LCD Click wheel in a depressed state.  If you do not have
+   *                    an LCD, you must specify a value if you use P.
+   *
+   *   Q #  Multiplier  Retraction Multiplier.  Normally not needed.  Retraction defaults to 1.0mm and
+   *                    un-retraction is at 1.2mm   These numbers will be scaled by the specified amount
+   *
+   *   R #  Repeat      Prints the number of patterns given as a parameter, starting at the current location.
+   *                    If a parameter isn't given, every point will be printed unless G26 is interrupted.
+   *                    This works the same way that the UBL G29 P4 R parameter works.
+   *
+   *                    NOTE:  If you do not have an LCD, you -must- specify R.  This is to ensure that you are
+   *                    aware that there's some risk associated with printing without the ability to abort in
+   *                    cases where mesh point Z value may be inaccurate.  As above, if you do not include a
+   *                    parameter, every point will be printed.
+   *
+   *   S #  Nozzle      Used to control the size of nozzle diameter.  If not specified, a .4mm nozzle is assumed.
+   *
+   *   U #  Random      Randomize the order that the circles are drawn on the bed.  The search for the closest
+   *                    undrawn cicle is still done.  But the distance to the location for each circle has a
+   *                    random number of the size specified added to it.  Specifying S50 will give an interesting
+   *                    deviation from the normal behaviour on a 10 x 10 Mesh.
+   *
+   *   X #  X Coord.    Specify the starting location of the drawing activity.
+   *
+   *   Y #  Y Coord.    Specify the starting location of the drawing activity.

  * M100 Free Memory Watcher
- * 
+ *
  * This code watches the free memory block between the bottom of the heap and the top of the stack.
  * This memory block is initialized and watched via the M100 command.
- * 
- * M100 I Initializes the free memory block and prints vitals statistics about the area
- * M100 F Identifies how much of the free memory block remains free and unused.  It also
- *    detects and reports any corruption within the free memory block that may have
- *    happened due to errant firmware.
- * M100 D Does a hex display of the free memory block along with a flag for any errant
- *    data that does not match the expected value.
- * M100 C x Corrupts x locations within the free memory block.   This is useful to check the
- *    correctness of the M100 F and M100 D commands.

Marlin/example_configurations/CL-260/README.txt

+This is an example configuration for the CL-260.
+Change Z_MAX_POS to 300 for the CL-260MAX.
+
+(The printer is available on AliExpress; be aware that this is not a beginner's
+printer -- it needs tweaking and some parts replaced before being decent.)
+
+The printer comes with a quite old Marlin, the sources are available here:
+http://www.thingiverse.com/thing:1635830/ and I recommend replacing them.
+
+The setting "works" for my printer and the extruder using my calibration value.
+You might want to tweak some settings, e.g enable EEPROM, increase default Z speed, adjust homing speeds,...
+
+Have fun!

-* VM8201 uses "DISPLAY_CHARSET_HD44870_JAPAN" and "ULTIMAKERCONTROLLER"
+* VM8201 uses "DISPLAY_CHARSET_HD44870 JAPANESE" and "ULTIMAKERCONTROLLER"
 * german (de) translation with umlaut is supported now - thanks to @AnHardt for the great hardware based umlaut support
 
-I [@CONSULitAS](https://github.com/CONSULitAS) tested the changes on my K8200 with 20x4-LCD and Arduino 1.6.1 for Windows (SD library added to IDE manually) - everything works well.

- * TWI/I2C BUS
- *
- * This feature is an EXPERIMENTAL feature so it shall not be used on production
- * machines. Enabling this will allow you to send and receive I2C data from slave
- * devices on the bus.
- *
- * ; Example #1
- * ; This macro send the string "Marlin" to the slave device with address 0x63 (99)
- * ; It uses multiple M155 commands with one B<base 10> arg
- * M155 A99  ; Target slave address
- * M155 B77  ; M
- * M155 B97  ; a
- * M155 B114 ; r
- * M155 B108 ; l
- * M155 B105 ; i
- * M155 B110 ; n
- * M155 S1   ; Send the current buffer
- *
- * ; Example #2
- * ; Request 6 bytes from slave device with address 0x63 (99)
- * M156 A99 B5
- *
- * ; Example #3
- * ; Example serial output of a M156 request
- * echo:i2c-reply: from:99 bytes:5 data:hello
