after install image_optim i can't find image_optim.yml file. I need add own config

[OlgaBurtyka]

Hi! Please, explain me where i can find or create image_optim.yml(I never can find it)?

After installed i find usr/local/bin/image_optim
there was this content
" require 'rubygems'

version = ">= 0"

if ARGV.first
str = ARGV.first
str = str.dup.force_encoding("BINARY") if str.respond_to? :force_encoding
if str =~ /\A_(.*)_\z/
version = $1
ARGV.shift
end
end

gem 'image_optim', version
load Gem.bin_path('image_optim', 'image_optim', version) "

---

But i need add image_optim.yml file with this setting:

allow_lossy: true # Small images through lossy compression
verbose: false # Verbose output

advpng:
level: 4 # Compression level: 0 - don't compress, 1 - fast,
#2 - normal, 3 - extra, 4 - extreme

gifsicle:
level: 3 # Compression level: 1 - light and fast, 2 - normal,
#3 - heavy (slower)
careful: false # Avoid bugs with some software

jpegoptim:
max_quality: 70 # Maximum image quality factor 0..100, ignored if
# allow_lossy is false

jpegrecompress:
quality: 1 # JPEG quality preset: 0 - low, 1 - medium, 2 - high,
#3 - veryhigh

optipng:
level: 7 # Optimization level preset: 0 - least, 7 - best

pngquant:
quality: !ruby/range 50..75 # Quality min..max - don't save below min,
# use less colors below max
speed: 1 # Speed/quality trade-off: 1 - slow, 3 - default,
#11 - fast & rough

pngout: false
svgo: false

I used magento CMS and Ubuntu. Please say me where need place image_optim.yml file, how setup and apply canges from image_optim.yml? Thanks

How is image_optim integrated in magento CMS?
I would try to create a file .image_optim.yml (note the first dot) in the root of the project. Another option is to set config for user by putting config in ~/.config/image_optim.yml (check that environment variable XDG_CONFIG_HOME is not set by running echo $XDG_CONFIG_HOME).

I had to create mine manually as well. myapp/.image_optim.yml.
