+## 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
+
 This repository has different grunt tasks for different uses. The source code is in the [Gruntfile](https://github.com/publiclab/image-sequencer/blob/main/Gruntfile.js).
 
 The following command is used for running the tasks: `grunt [task-name]`. Here `[task-name]` should be replaced by the name of the task to be run. To run the default task run `grunt` without any options.

 This method returns an object which defines the name and inputs of the modules. If a module name (hyphenated) is passed in the method, then only the details of that module are returned.
 
 The `notify` function takes two parameters `msg` and `id`, former being the message to be displayed on console (in case of CLI and node ) and a HTML component(in browser). The id is optional and is useful for HTML interface to give appropriate IDs.
+
+## 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 
+
+```
