 ## Development
 
-### Web Extension Development
+### Running Locally
 
-Since Firefox 57, this extension can now be run without any of the legacy components that were previously needed.
+#### Via WebExtensions API (web-ext)
 
-1. Install web-ext with npm
-2. cd webextension; web-ext run -f Nightly
+1. Install the [web-ext](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Getting_started_with_web-ext) tool.
+2. Run `web-ext run -s src/`. This launches Firefox and installs the extension automatically.
 
-This will work in other builds of Firefox however certain features won't work and you will need to manually flip preferences to enable containers. All other sections of this guide talk about using the legacy setup with jpm.
+This tool provides some additional development features, such as [automatic reloading](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Getting_started_with_web-ext#Automatic_extension_reloading).
 
+#### Via about:debugging in Firefox
 
-## Legacy Development
+1. Open the `about:debugging` page in Firefox.
+2. Click on `This Firefox`.
+3. Click on [Load Temporary Add-on](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Temporary_Installation_in_Firefox).
+4. Select `src/manifest.json`.
 
-### Development Environment
-
-Add-on development is better with [a particular  environment](https://developer.mozilla.org/en-US/Add-ons/Setting_up_extension_development_environment). One simple way to get that environment set up is to install the [DevPrefs add-on](https://addons.mozilla.org/en-US/firefox/addon/devprefs/). You can make a custom Firefox profile that includes the DevPrefs add-on, and use that profile when you run the code in this repository. 
-
-1. Make a new profile by running `/path/to/firefox -P`, which launches the profile editor. "Create Profile" -- name it whatever you wish (e.g. 'addon_dev') and store it in the default location. It's probably best to deselect the option to "Use without asking," since you probably don't want to use this as your default profile.
-
-2. Once you've created your profile, click "Start Firefox". A new instance of Firefox should launch. Go to Tools->Add-ons and search for "DevPrefs". Install it. Quit Firefox.
-
-3. Now you have a new, vanilla Firefox profile with the DevPrefs add-on installed. You can use your new profile with the code in _this_ repository like so:
-
-#### Run the `.xpi` file in an unbranded build
-Release & Beta channels do not allow un-signed add-ons, even with the DevPrefs. So, you must run the add-on in an [unbranded build](https://wiki.mozilla.org/Add-ons/Extension_Signing#Unbranded_Builds):
-
-1. Download and install an un-branded build of Firefox
-2. Download the latest `.xpi` from this repository's releases
-3. Run the un-branded build of Firefox with your DevPrefs profile
-4. Go to `about:addons`
-5. Click the gear, and select "Install Add-on From File..."
-6. Select the `.xpi` file
-
-#### Correct prefs
-
-Whilst this is still using legacy code to test you will need the following in your profile:
-
-Change the following prefs in about:config:
-
-- extensions.legacy.enabled = true
-- xpinstall.signatures.required = false
-
-
-#### Run the TxP experiment with `jpm`
-
-1. `git clone git@github.com:mozilla/testpilot-containers.git`
-2. `cd testpilot-containers`
-3. `npm install`
-4. `./node_modules/.bin/jpm run -p /Path/To/Firefox/Profiles/{junk}.addon_dev -b FirefoxBeta` (where FirefoxBeta might be: ~/<reponame>/obj-x86_64-pc-linux-gnu/dist/bin/firefox or ~/<downloadedFirefoxBeta>/firefox)
-
-Check out the [Browser Toolbox](https://developer.mozilla.org/en-US/docs/Tools/Browser_Toolbox) for more information about debugging add-on code.
-
-### Building .xpi
-
-To build a local testpilot-containers.xpi, use the plain [`jpm
-xpi`](https://developer.mozilla.org/en-US/Add-ons/SDK/Tools/jpm#jpm_xpi) command,
-or run `npm run build`.
-
-### Signing an .xpi
-
-To sign an .xpi, use [`jpm
-sign`](https://developer.mozilla.org/en-US/Add-ons/SDK/Tools/jpm#jpm_sign)
-command.
-
-Note: You will need to be [an author on the AMO
-add-on](https://addons.mozilla.org/en-US/developers/addon/containers-experiment/ownership).
+Here is a [video](https://www.youtube.com/watch?v=cer9EUKegG4) that demonstrates how to do this.
 
 ### Testing
-TBD
+
+* Install dependencies:
+
+  ```
+  npm install
+  ```
+
+* Run all tests:
+
+  ```
+  npm run test
+  ```
+
+* Only run the linter:
+
+  ```
+  npm run lint
+  ```
+
+There is a timeout test that sometimes fails on certain machines, so make sure to run the tests on your clone before you make any changes to see if you have this problem.
 
 ### Distributing
-TBD
+#### Make the new version
+
+1. Bump the version number in `package.json` and `manifest.json`
+2. Commit the version number bump
+3. Create a git tag for the version: `git tag <version>`
+4. Push the tag up to GitHub: `git push --tags`
+
+#### Publish to AMO
+
+1. `npm run-script build`
+2. [Upload the `.zip` to AMO](https://addons.mozilla.org/developers/addon/multi-account-containers/versions/submit/)
+
+#### Publish to GitHub
+Finally, we also publish the release to GitHub for those followers.
+
+1. Download the signed `.xpi` from [the addon versions page](https://addons.mozilla.org/developers/addon/multi-account-containers/versions)
+2. [Make the new release on
+   GitHub](https://github.com/mozilla/multi-account-containers/releases/new)
+   * Use the version number for "Tag version" and "Release title"
+   * Release notes: copy the output of `git log --no-merges --pretty=format:"%h %s" <previous-version>..<new-version>`
+   * Attach binaries: select the signed `.xpi` file

-           Detecting redirects on "new tab" opening actions is pretty hard as we don't get tab history:
-           - Redirects happen from Short URLs and tracking links that act as a gateway
-           - Extensions don't provide a way to history crawl for tabs, we could inject content scripts to do this
-               however they don't run on about:blank so this would likely be just as hacky.
-           We capture the time the tab was created and close if it was within the timeout to try to capture pages which haven't had user interaction or history.
