+# Welcome to the most strict eslint config ever
+
+## Philosophy
+- contains all rules
+- almost all rules enabled
+- this config is highly opinionated
+
+## Where to use
+- anywhere
+- for tests better to add `env:"node"` and disable `newline-per-chained-call` rule
+
+## What is disabled
+- `no-eq-null` - duplicates `eqeqeq:smart`
+- `no-restricted-imports`, `no-restricted-modules` - dependant on project requirements
+- `id-match` - not found any particular use of this rule, `camelCase` is enough
+- `jsx-quotes` - I don't use jsx so I don't care
+- `no-plusplus` - why not `++`? It's nice to use when you know what you are doing
+- `no-restricted-syntax` - duplicates `no-with` and `no`
+- `no-ternary` - why not? but nested ternary please
+- `require-jsdoc`- nice thing, but hard to follow
+- `spaced-comment` - nice for meaningful comments, but hard to argue when you commenting peaces of code
+- `wrap-regex` - no need
+
+## What is tweaked
+- `dot-location` - `property` mode enabled
+- `eqeqeq` - `smart` mode enabled
+- `no-implicit-coercion` - boolean implicit coercion enabled
+- `no-use-before-define` - usage of `function` declarations before usage are allowed
+- `no-mixed-requires`- `grouping` and `allowCall` checks enabled
+- `func-style` - `declaration` only please
+- `indent` - 2 spaces rulezzz!
+- `linebreak-style` - unix only
+- `one-var` - `never` use one `var|let|const` per block
+- `padded-blocks` - `never` add useless padding
+- `quote-props` - quote properties only `as-needed` and `keywords`
+
+## Contribution
+- what I really appreciate is configs for IDEs
+- to change any rule you should have strong arguments and not only opinion
