+Introduction ~
+
+ConTeXt, similarly to LaTeX, is a macro-based typesetting system built on TeX:
+>
+	https://wiki.contextgarden.net
+	https://wiki.contextgarden.net/Vim
+<
+The ConTeXt plugin provides syntax highlighting, completion and support for
+typesetting ConTeXt documents. The recommended way to typeset a document is to
+use |:ConTeXt|. This will invoke the `mtxrun` script that is found in $PATH.
+
+For more fine grained control over the command and its environment, you may
+invoke `context.Typeset()` directly (or `context#Typeset()` from legacy Vim
+script). For instance, if you have installed a version of ConTeXt in
+`~/context`, you may define a function to use it (you may put the following
+code in `~/.vim/after/ftplugin/context.vim`) similar to the following:
+>
+	import autoload 'context.vim'
+
+	def MyConTeXt()
+	    const env = {'PATH':
+	      printf("%s/context/tex/texmf-<os>-<arch>/bin:%s", $HOME, $PATH)}
+	    context.Typeset("%", env)
+	enddef
+<
+and perhaps use it with a mapping:
+>
+	nnoremap <silent><buffer><leader>t <scriptcmd>MyConTeXt()<cr>
+<
+`context.Typeset()` accepts a third optional argument to specify a custom
+typesetting command. Such argument must be a function that takes a path and
+returns the command as a List. For example:
+>
+	def ConTeXtCustomCommand(path: string): list<string>
+	  return ['mtxrun', '--script', 'context', '--nonstopmode, path]
+	enddef
+
+	context.ConTeXtTypeset("%", v:none, ConTeXtCustomCommand)
+<
+Large projects are often organized as a root document and various chapter
+files. When editing a chapter file, it is convenient to invoke |:ConTeXt|
+directly on it, rather than having to switch to the root file. A "magic line"
+can be added at the beginning of each chapter file, which specifies the
+relative path to the root file. For instance:
+>
+	% !TEX root = ../MyRoot.tex
+<
+Vim searches for the magic line in the first ten lines of the current buffer:
+if it is found, the document specified by that line is typeset rather than the
+one in the current buffer. The root document does not have to be opened in
+Vim.
+
+To extend completion and syntax highlighting, you may generate supporting
+files using ConTeXt and add them to your configuration. If you configuration
+resides in `~/.vim`, you may use these commands:
+>
+	mkdir -p ~/.vim/syntax/shared
+	cd ~/.vim/syntax/shared
+	mtxrun --script interface --vim
+<
+The last command will create the following syntax files:
+
+- `context-data-context.vim`;
+- `context-data-interfaces.vim`;
+- `context-data-metafun.vim`;
+- `context-data-tex.vim`. 
+
+The same command can be used to update those syntax files.
+
+							*ft-context-commands*
+Commands ~
+					*:ConTeXt*
+Start a background |job| to typeset the document in the current buffer. The
+command accepts an optional buffer's name, if you want to typeset a document
+that is in a different buffer.
+
+					*:ConTeXtLog*
+Edit the log file corresponding to the source in the current buffer.
+
+					*:ConTeXtJobsStatus*
+Echo the number of jobs currently running in the background.
+
+					*:ConTeXtStopJobs*
+Stop all the ConTeXt jobs currently running in the background.
+
+							*ft-context-settings*
+Settings ~
+					*'b:context_ignore_makefile'*
+					*'g:context_ignore_makefile'*
+`make` can be used to (synchronously) typeset a document. If a Makefile exists
+and this option is not set, standard `make` is used. If this option is set,
+`mtxrun` is invoked instead, even if a Makefile exists.
+>
+	g:context_ignore_makefile = 0
+<
+NOTE: before using `make`, set the working directory of the buffer to the
+directory of the file to be typeset.
+					*'b:context_include'*
+					*'g:context_include'*
+Dictionary of filetype/GROUP pairs for which syntax highlighting should be
+activated between \startGROUP and \stopGROUP. The default is to highlight XML
+between `\startXML` and `\stopXML`.
+>
+	g:context_include = {'xml': 'XML'}
+
+NOTE: Lua and MetaPost are always highlighted within the respective blocks.
+
+					*'g:no_context_maps'*

+Introduction ~
+This filetype plugin provides extensive support for editing METAFONT and
+MetaPost documents, including syntax coloring, indentation, and completion.
+
+Defining indentation rules for METAFONT and MetaPost code is tricky and
+somewhat subjective, because the syntax is quite liberal. The plugin uses some
+heuristics that work well most of the time, but in particular cases you may
+want to to override the automatic rules, so that the manually defined
+indentation is preserved by commands like `gg=G`.
+
+This can be achieved by appending `%>`, `%<`, `%=` or `%!` to a line to
+explicitly control the indentation of the next line. The `<` and `>` symbols
+may be repeated many times: for instance, `%>>` will cause the next line to be
+indented twice. Of course, `%<` means that the next line should be
+de-indented; `%=` sets the indentation of the next line to be equal to the
+indentation of the current line; and `%!` means that the indentation of the
+next line should not change from whatever it has been manually set.
+
+For example, this is the default indentation of a simple macro:
+>
+   def foo =
+       makepen(
+           subpath(T-n,t) of r
+           shifted .5down
+           --subpath(t,T) of r shifted .5up -- cycle
+       )
+       withcolor black
+   enddef
+<
+By adding the special comments, the indentation can be adjusted arbitrarily:
+>
+   def foo =
+       makepen(
+           subpath(T-n,t) of r  %>
+               shifted .5down   %>
+                   --subpath(t,T) of r shifted .5up -- cycle   %<<<
+       )
+       withcolor black
+   enddef
+<
+							*ft-metapost-commands*
+Commands ~
+					*:FixBeginfigs*
+Renumber beginfig() blocks in the current buffer so that the n-th figure has
+number n. MetaPost only.
+
+							*ft-metapost-settings*
+							*ft-metafont-settings*
+Settings ~
+					*'g:mf_other_macros'*
+Highlight some other basic macro names, e.g., from cmbase, logo, etc. This is
+set to 1 by default in METAFONT buffers, and it is set to 0 by default in
+MetaPost buffers.
+
+					*'g:mf_plain_macros'*
+Highlight keywords defined by plain.mf. This is set to 1 by default in
+METAFONT buffers, and it is set to 0 by default in MetaPost buffers.
+
+					*'g:mf_plain_modes'*
+Highlight keywords defined by modes.mf. This is set to 1 by default in
+METAFONT buffers, and it is set to 0 by default in MetaPost buffers.
+
+					*'g:mp_close_tag'*
+Define additional keywords that end indented blocks. For instance, if you
+define:
+>
+	g:mp_end_tag = ['\<endfoo\>']
+<
+any line starting with `endfoo` will be de-indented compared to its previous
+line.
+>
+	g:mp_close_tag = []
+<
+					*'b:mp_metafun'*
+					*'g:mp_metafun'*
+If set to 1, highlight ConTeXt's MetaFun keywords. MetaPost only.
+>
+	g:mp_metafun = 0
+<
+					*'g:mp_mfplain_macros'*
+Highlight keywords defined by mfplain.mp. MetaPost only.
+>
+	g:mp_mfplain_macros = 1
+<
+					*'g:mp_open_tag'*
+Define additional keywords that start indented blocks. For instance, if you
+define:
+>
+	g:mp_open_tag = ['\<beginfoo\>']
+<
+the line following `beginfoo` will be indented.
+>
+	g:mp_open_tag = []
+<
+					*'g:mp_other_macros'*
+Highlight keywords defined by all base macro packages (boxes, rboxes, format,
+graph, marith, sarith, string, TEX). This option affects only MetaPost
+buffers.
+>
+	g:mp_other_macros = 1
+<
+					*'g:mp_plain_macros'*
+Highlight keywords defined by plain.mp. MetaPost only.
+>
+	g:mp_plain_macros = 1
+<
+					*'g:no_mp_maps'*
+					*'g:no_mf_maps'*
+When set, do not define any mapping in buffers with the corresponding
+filetype.
