-## Procedure
-
-1.  Draw the graphical part of the symbol (lines, boxes, delineation of
-    internal connections)
-2.  Add pins (keyboard shortcut: ap) and fill in the attributes
-    'pinlabel','pinnumber','pinseq','pintype'. Normally, the first two
-    attributes are kept visible while the other two are kept invisible.
-    Use the pin name mentioned in the device datasheet as your
-    'pinlabel'. 'pinnumber' and 'pinseq' have the same value unless you
-    are using [slotting](slotting "wikilink"). 'pintype' should be one
-    of the ten values mentioned in the ![ gEDA Master Attribute
-    Document](geda-attributes-Hvezda.pdf
-    " gEDA Master Attribute Document") and should be in lower case.
-3.  Add at least the following symbol attributes to the symbol:
-    'refdes', 'device', 'value', 'description', 'author', 'numslots' and
-    'footprint'
-4.  Make all attributes invisible (keyboard shortcut 'en') and translate
-    the symbol to the origin using the keyboard shortcut 'et'. This
-    ensures that the symbol appears at the right place when invoked.
-5.  Run [gsymcheck](gsymcheck "wikilink") on the symbol file to ensure
-    it is alright
-
-## Hierarchical Symbols
-
-These are symbols which represent underlying schematics (or netlists).
-There are some additional requirements in this case:
-
-1.  *Source=* attribute pointing to source schematic
-2.  *model-name=* attribute pointing to model name or subcircuit name
-    with parameters
-3.  *file=* pointing to relative path of the sub-circuit prototype
-    (SPICE subckt file)
-
-## Also see:
-
-1.  Some guidelines on the gEDA library page: on
-    <http://www.gedasymbols.org/csv.html>
-2.  See the ![ gEDA Master Attribute
-    Document](geda-attributes-Hvezda.pdf
-    " gEDA Master Attribute Document") for the meanings of the
-    attributes.
-3.  Automated tool for converting schematic to symbol:
-    [geda\_sch2sym](geda_sch2sym "wikilink")
