+When the code in the `master` branch is considered to be stable, a release can
+be made. This is the procedure:
 
-1. Tag the last commit with a version number (in the format `vx`, where x is the extension's [version number](https://developer.chrome.com/extensions/manifest/version) for that release) by running `git tag -a vx -m "vx"`. Note that the tag should be an annotated tag and not a lightweight tag, and it must be pushed to Gerrit after being created.
-2. Build the extension for both the stable and beta channels (this is explained in the next section). This will output a ZIP file for each release channel and each supported browser.

 ### Submitting to the Chrome Web Store
-1. [Upload both release files](https://developer.chrome.com/webstore/publish#upload-your-item) to the Chrome Web Store, one for each release channel.
-2. [Submit both releases](https://developer.chrome.com/webstore/publish#submit-your-item-for-publishing) to be reviewed by the Chrome Web Store team, but in the case of the stable channel uncheck the "Publish automatically after it has passed review" option.
-3. Upload the beta release file to the [GitHub releases page](https://github.com/avm99963/infinitegforums/releases) under the newly created tag. Mark that release as a pre-release at GitHub.

 4. Wait until the beta release is reviewed and approved by Google.
-5. Test again the extension by using the beta channel. Check if the options have been transfered correctly from version to version, and wait some days (for instance between 3 and 5 days) to see if other people report issues with the updated version.
-6. If everything goes well, publish the update in the stable channel. The updated version should have already been reviewed by the Chrome Web Store team at this time.
-7. Update the release file in the GitHub releases page by removing the beta release file and uploading the stable release file. Also, remove the pre-release label.

-If during this process the release wasn't approved by Google or an issue was found during beta testing, a new release which fixes this should be created.

 ### Submitting to addons.mozilla.org
 The procedure is similar to the one with the Chrome Web Store.
 
-@TODO: Add more details once the first version of the extension has been uploaded to addons.mozilla.org.

 ## Build the extension
-A zip file with the contents of the extension, which can be uploaded to the Chrome Web Store and addons.mozilla.org, can be created with any of the following procedures:

 ### Using the release.bash script
-Run `bash release.bash -h` in order to learn how to use this command. To summarize, the command accepts the `--channel` and `--browser` flags (or their short versions `-c` and `-b`).

 ## Testing notes
-When testing the extension during development, you don't have to build the extension each time you want to import an updated version to Chrome/Firefox. Instead, run `bash generateManifest.bash {browser}` once, where `{browser}` is either `CHROMIUM` or `GECKO`, and this will generate a `manifest.json` file for the specified browser in the `src` directory. Now, you can load the `src` folder directly in the browser in order to import the extension, which removes the need to build it. When the `manifest.gjson` file is modified, you'll have to generate the manifest again.

-To test translations, you might want to set your browser's locale. This section tells you how to set the locale in [Windows](https://developer.chrome.com/extensions/i18n#testing-win), [Mac OS X](https://developer.chrome.com/extensions/i18n#testing-mac), [Linux](https://developer.chrome.com/extensions/i18n#testing-linux), and [Chrome OS](https://developer.chrome.com/extensions/i18n#testing-chromeos).
