 ## How to Build
 
-If you just want to use crow, copy amalgamate/crow_all.h and include it.
+If you just want to use crow, generate `crow_all.h` (use script `amalgamate/merge_all.py`) and include it.
 
 ### Requirements
 
- - C++ compiler with good C++11 support (tested with g++>=8).
+ - C++ compiler with good C++14 support (tested with g++>=8).
  - boost 1.7 library.
  - (optional) CMake to build tests and/or examples.
  - (optional) Linking with tcmalloc/jemalloc is recommended for speed.
 
- - Now supporting VS2013 with limited functionality (only run-time check for url is available.)

-overview: |
-  Interpolation tags are used to integrate dynamic content into the template.
-
-  The tag's content MUST be a non-whitespace character sequence NOT containing
-  the current closing delimiter.
-
-  This tag's content names the data to replace the tag.  A single period (`.`)
-  indicates that the item currently sitting atop the context stack should be
-  used; otherwise, name resolution is as follows:
-    1) Split the name on periods; the first part is the name to resolve, any
-    remaining parts should be retained.
-    2) Walk the context stack from top to bottom, finding the first context
-    that is a) a hash containing the name as a key OR b) an object responding
-    to a method with the given name.
-    3) If the context is a hash, the data is the value associated with the
-    name.
-    4) If the context is an object, the data is the value returned by the
-    method with the given name.
-    5) If any name parts were retained in step 1, each should be resolved
-    against a context stack containing only the result from the former
-    resolution.  If any part fails resolution, the result should be considered
-    falsey, and should interpolate as the empty string.
-  Data should be coerced into a string (and escaped, if appropriate) before
-  interpolation.

-  Section tags and End Section tags are used in combination to wrap a section
-  of the template for iteration
-
-  These tags' content MUST be a non-whitespace character sequence NOT
-  containing the current closing delimiter; each Section tag MUST be followed
-  by an End Section tag with the same content within the same section.
-
-  This tag's content names the data to replace the tag.  Name resolution is as
-  follows:
-    1) Split the name on periods; the first part is the name to resolve, any
-    remaining parts should be retained.
-    2) Walk the context stack from top to bottom, finding the first context
-    that is a) a hash containing the name as a key OR b) an object responding
-    to a method with the given name.
-    3) If the context is a hash, the data is the value associated with the
-    name.
-    4) If the context is an object and the method with the given name has an
-    arity of 1, the method SHOULD be called with a String containing the
-    unprocessed contents of the sections; the data is the value returned.
-    5) Otherwise, the data is the value returned by calling the method with
-    the given name.
-    6) If any name parts were retained in step 1, each should be resolved
-    against a context stack containing only the result from the former
-    resolution.  If any part fails resolution, the result should be considered
-    falsey, and should interpolate as the empty string.
-  If the data is not of a list type, it is coerced into a list as follows: if
-  the data is truthy (e.g. `!!data == true`), use a single-element list
-  containing the data, otherwise use an empty list.
-
-  For each element in the data list, the element MUST be pushed onto the
-  context stack, the section MUST be rendered, and the element MUST be popped
-  off the context stack.
-
-  Section and End Section tags SHOULD be treated as standalone when
-  appropriate.

-overview: |
-  Lambdas are a special-cased data type for use in interpolations and
-  sections.
-
-  When used as the data value for an Interpolation tag, the lambda MUST be
-  treatable as an arity 0 function, and invoked as such.  The returned value
-  MUST be rendered against the default delimiters, then interpolated in place
-  of the lambda.
-
-  When used as the data value for a Section tag, the lambda MUST be treatable
-  as an arity 1 function, and invoked as such (passing a String containing the
-  unprocessed section contents).  The returned value MUST be rendered against
-  the current delimiters, then interpolated in place of the section.
