-## Linting
-
-We are now using `eslint` and `husky` to help lint and format our code each time we commit. Eslint defines coding standards and helps in cleaning up the code. To run eslint for checking errors globally or within a specific file run:
-
-```
-npx eslint . 
-
-npx eslint <file path>
-```
-And to fix those errors globally or in a file, run these in your terminal:
-```
-npx eslint . --fix
-
-npx eslint <file path> --fix
-```
-Be sure to not include the angular brackets(<>).
-
-Husky ensures automation of the above steps with git-hooks(eg. git add,git commit..). However we don't want to check and fix changes of the entire codebase with each commit and that the fixes made by eslint appear unstaged and require us to commit them  again and that is where lint-staged helps.
-
-If we want `husky` to not verify the commit and push it anyway, use `git commit -m "message" --no-verify.`

 ## Grunt Tasks

-## UI Helper Methods
-
-### scopeQuery
-
-###### Path: `/examples/lib/scopeQuery.js`
-
-The method returns a scoped `jQuery` object which only searches for elements inside a given scope (a DOM element).
-
-To use the method, 
-* import the `scopeSelector` and `scopeSelectorAll` methods from `lib/scopeQuery.js`
-* call the methods with scope as a parameter
-	
-```js
-var scopeQuery = require('./scopeQuery');
-
-var $step = scopeQuery.scopeSelector(scope),
-    $stepAll = scopeQuery.scopeSelectorAll(scope);	
-```
-This will return an object with a constructor which returns a `jQuery` object (from inside the scope) but with new `elem` and `elemAll` methods.
-
-#### Methods of the Returned Object
-* `elem()`: Selects an element inside the scope; 
-* `elemAll()`: Selects all the instances of a given element inside the scope;
-
-#### Example
-
-```js
-//The scope is a div element with id=“container“ and there are three divs in it 
-//with ids „1“, „2“, and „3“, and all of them have a „child“ class attribute
-
-var $step = require('./scopeQuery').scopeSelector(document.getElementById('container'));
-
-$step('#1'); // returns the div element with id=“1“
-$step('#1').hide().elemAll('.child').fadeOut(); // abruptly hides the div element with id=“1“ and fades out all other div elements
-```
-
-These two methods are chainable and will always return elements from inside the scope.
-
-#### Usage
-
-Instead of using
-
-```js
-$(step.ui.querySelector('query')).show().hide();
-$(step.ui.querySelectorAll('q2')).show().hide();
-```
-The following code can be used
-
-```js
-$step('query').show().hide();
-$stepAll('q2').show().hide();
-```

-## Using WebAssembly for heavy pixel processing
-
-Any module which uses the `changePixel` function gets WebAssembly acceleration (`wasm`). Both node and browser code use WebAssembly and the only code which falls back to non-`wasm` code is the [browserified unit tests](https://github.com/publiclab/image-sequencer/blob/main/test/core/sequencer/benchmark.js).
-
-The main advantage we get using `wasm` is blazing fast speed attained in processing pixels for many modules that is very clear from [checking module benchmarks](https://travis-ci.org/publiclab/image-sequencer/jobs/544415673#L1931).
-
-
-The only limitation is that browser and node code for `wasm` had to be written separately, and switched between. This is because in browser we use `fetch` to retrieve the compiled `wasm` program while in node we use the `fs` module, each of which cannot be used in the other's environment.
-
-
-`wasm` mode is enabled by default. If you need to force this mode to be on or off, you can use the `useWasm` option when initializing ImageSequencer:
-
-```js
-let sequencer = ImageSequencer({useWasm:true}) // for wasm mode or simply
-
-let sequencer = ImageSequencer() // also for wasm mode i.e. default mode
-
-let sequencer = ImageSequencer({useWasm:false}) //for non-wasm mode
