Help with installing Type1 fonts in MikTex

I am a LaTeX amateur and I've struggled for hours with the
installation of a new type1 font in MikTex. Why is this so hilariously
difficult? I've read the many guides on the internet, including the
elaborate 'The Font Installation Guide' by Philipp Lehman. Maybe
somebody here can tell me what I'm doing wrong.

My goal is to install an Adobe Bembo font. I've renamed the
relevant .afm and .pfb files (regular, italic, bold, bolditalic), in
accordance with the Berry convention, to pbbr8a, pbbri8a, pbbb8a and
pbbbi8a (with the right extensions).

I have applied 'fontinst' to these files, as explained in the various
guides. And I have applied both 'pltotf' and 'vptovf' to the results,
and placed the relevant files in the relevant directories (.tfm in tfm/
adobe/bembo, .pfb in type1/abobe/bembo, .vf in vf/adobe/bembo, and .fd
in tex/latex/adobe/bembo).

I have created a map file, as explained in The Font Installation
Guide. My file looks like this:

pbbr8r Bembo "TeXBase1Encoding ReEncodeFont" <8r.enc <pbbr8a.pfb
pbbro8r Bembo "TeXBase1Encoding ReEncodeFont 0.167 SlantFont" <8r.enc
<pbbr8a.pfb
pbbri8r Bembo-Italic "TeXBase1Encoding ReEncodeFont" <8r.enc
<pbbri8a.pfb
pbbb8r Bembo-Bold "TeXBase1Encoding ReEncodeFont" <8r.enc <pbbb8a.pfb
"TeXBase1Encoding ReEncodeFont"
pbbbo8r Bembo-Bold "TeXBase1Encoding ReEncodeFont 0.167 SlantFont"
<8r.enc <pbbb8a.pfb
pbbbi8r Bembo-BoldItalic "TeXBase1Encoding ReEncodeFont" <8r.enc
<pbbbi8a.pfb

I have placed this mapfile in dvips/config. I'm not clear on what
comes next, because various guides say conflicting things.

Lehman's guide says: add links to the mapfile to certain config files.
I've opened config.ps in dvips/config and added the required line.
Then it says: update file structure (or something along those lines).
How do I go about that? Specifically, in the case of MiKTeX?

Currently, the error I get reads:

LaTeX Font Warning: Font Shape 'OT1/pbb/m/n' undefined
<font> using 'OT1/pcr/m/n' instead on input line 7
LaTeX Font Warning: Font Shape 'OT1/pbb/bx/n' undefined
