-====== How to ... ======
-==== Multicache - creating waypoints ====
-You can type coordinates to note field, select them and convert to waypoint via context menu.
-{{:en:wpt.png|Creating waypoint}}
-^Note      ^How PD works ^
-| N 50 41.123 E 15 10.456\\ 50 41.123 15 10.456\\ 50d41.123 15d10.456 | d or space meand degrees, coordinates are read as thery are typed, hemisphere N/S and E/W is optional |
-| 41.123 10.456       | numbers are seen as minutes, degrees are taken from cache coordinates |
-| 123 456             | numbers are seen as thousandth of minutes, degrees and whole minutes are taken from cache coordinates |
-==== Azimuth and distance - projection ====
-If the author assigned to cache only the direction and distance PocketDrake will help you determine where to go. The process is simple:
-  * add waypoint on starting coordinates, where the distance is calculated from
-  * use the right arrow button to open a dialog box for setting the azimuth and distance
-  * after tapping OK the original waypoint coordinates are replaced with new ones
-==== Formula Solver ====
-=== Basics ===
-Two information is necessary to solve a formula
-  * variables
-  * formula itself
-Variables are usually commot for all waypoints, they are stored in cache note.
-There could be more waypoints with different formulas, we store forumlas in waypoint note.
-Variables and formulas must me marked with special tags
-  <! variables !>
-  <? formulas ?>
-=== Formulas steb by step ===
-==1. Collect variables and write them into cache note, follow these simple rules: ==
-  * name and value is separated by colon or equal sign, example A=1 B:3
-  * variables must me separated by space or line break
-  * it is possible to assign more letters at a time, example ABC=456
-==2. Mark varibales block (it could be only one)==
-  * select block
-  * coose Mark variables from context menu

-==3. Copy formula from listing to clipboard ==
-==4. Crate waypoint ==
-==5. Add formula to waypoint ==
-{{:vars:3.png|Vložení vzorce}}
-(1) Use **Paste formulas**, PocketDrake adds necessary tags automatically\\
-(2) Adjust formula so that the first line of the formula is for the latitude (N/S) and the other for the longitude (E/W)\\
-(3) Open formula solver tapping **Calculate formulas**
-==6. Fine tune formulas==
-Edit formulas to follow basic syntax rules:
-  * separately calculated groups of digits are enclosed in square brackets [ ]
-  * supported math operations are add (+), subtract (-), multiply (*), divide (/), power (^) and round bracket
-  * priority of operators is respected, ie, first to multiply and divide and then add and subtract
-Use the **Normalize formulas** (1) to simplify edittind:
-  * replaces outer round brackets with square ones
-  * moves N/S and W/E to corresponding fields
-  * removes unnecessary characters
-Now, we can try **Calculate formulas** (2)
-{{:vars:4.png|Úprava vzorců}}
-==7. Calculation==
-If there is an error in the formula (wrong syntax, the brackets doesn't match, undefined variable), the error message appears in Result box, otherwise there are calculated coordinates.
-Digit sum (Σ box) is automatically calculated too.
