-==== Blindly Maintained ====
-A cam running ML but without [[#maintainer]] is called blindly maintained. This may happen after ML was ported to the cam some time ago and former maintainer is no longer working on it. \\
-Such camera models get updates when new builds are published but there may be nobody feeling responsible to do basic testing and quality control. Bugs may get introduced and remain unnoticed until an user stumbles across it and fill in bug report.
-==== Bootable Card ====
-A bootable card is an essential part of [[#ML startup process|ML's startup process]]. During installation some information is written into a hidden section of your installation medium. \\
-If a card is formated outside the cam or formated in a cam not actively running ML this information will get lost. Boot ability will not be affected by deleting files or directories.\\
-To make additional cards bootable it is recommended to redo ML installation for each card.
-==== Bootflag ====
-Some information written and stored in cam during ML installation. It will only be deleted by proper deinstallation. \\
-A cam with bootflag set will check if there is a [[#bootable card]] found in cam's card slot(s). It's an essential part of [[#ML startup process|ML's startup process]].

-==== Canon Basic Scripting ====
-Canon introduced Basic Scripting support in EOS camera line-up with Digic 8. It is available for all EOS cams hosting DiGiC 8 und X processors. Same functionionality is a long-standing part in PowerShot cameras (there for older DiGiC generations, too).\\
-It makes a dev's life a lot easier by allowing to set cam's [[#bootflag]] with some simple and portable lines of code. And other things, too.
-If you ever come across a statement like "Canon making ML development harder by introducing locked down cameras": This is proof of the very opposite!

-==== Main Build ====
-==== Maintainer ====
-A maintainer in ML microcosmos is a [[#dev|developer]] feeling responsible for a particular camera model. Maintaining a cam consists of tasks like programming, testing, quality control, porting ML to new firmware versions. \\
-Cameras without a maintainer are called [[#blindly supported]].
-==== ML Startup Process ====
-==== MLV ====
-==== Module ====
-Some parts of ML's feature set are not loaded by default. To use them you have to access Modules tab/screen activate them* and restart camera. After powerup module's menu options are visible in ML's tabs/screens.\\
-Some developers created custom modules not included in zipped ML builds. You can add modules by placing module file (*.mo) into card directory ML\Modules.
-There are two reasons to place ML features into modules:\\
-- Placing all functions into one single piece of software bloats memory requirements and may exceed camera limits for available memory during startup.\\
-- Modules are somehow easier to develop. Such lowering the bar how to make features happen in ML.
-Well known ML features codes as modules are: RAW/MLV recording, Dual-ISO, Silent Pics, ETTR ...

-==== Shutter Bug (EOS M) ====
-**Symptom**: EOS M can focus by half-press shutter but full-press won't work. Using touchscreen may lockup cam completely and you have to remove battery.\\
-**Cause**: Most likely a so called "race condition" at the very beginning of cam's startup process. ATM ML devs cannot fix that.\\
-**Cure**: None, at least in foreseeable future.\\
-**Workarounds**:   \\
-* Twist your lens in socket. Powerup cam. Twist lens into mount socket. \\
-* Use a fast card! \\
-Disclaimer: This entry contains no practical joke.

-===== T =====
-===== U =====
-==== UART ====
-A serial protocol interface/connector inside your cam. ML devs suppose it was implemented by Canon for diagnostics and for low-level maintainance/repair. \\
-By accessing it ML devs can read a lot of internal low-level data hidden from Canon menu. And in case of very-hard-to-hack cameras there may be a way to write data, too (for example: Enable bootflag). \\
-Physically accessing UART in older cams required opening cam and maybe even soldering wires to camera's cirtuit board. Later cams have a UART connector on board for easier access. \\
-On some of Canon's Digic 7, 8 and X cameras this UART is accessible without opening the camera by just removing a reusable rubber cover.

-==== YAMLMO ====
-Yet Another ML Menu Option. You may get this response after posting a [[#feature request]] asking for an additional menu option. ML staff is reluctant to add any new menu options because they feel strongly there already are too many and they want to avoid spreading the disease. ;-)
