README.md

 Adblock Browser
 ===============
 
 The Adblock Plus browser, based on Firefox for Android.
 
 Building
 --------
 
 First ensure that all dependencies are up to date by calling:
 
     ./ensure_dependencies.py
 
-Then just follow Mozilla's [Building Fennec][1] guide.
+Then just follow Mozilla's [Firefox for Android build instructions][1].
 
 
 Creating a multilocale build
 ----------------------------
 
 ### Automation ###
 
 While the manual process is still documented below, the easiest way to create a
-multi-locale build is to use: https://bitbucket.org/adblockplus/adblockbrowser-build.
+multi-locale build is to use [adblockbrowser-build][2].
 
 ### Preparations ###
 
 1. Create a folder outside of the Adblock Browser repo, e.g `abb-multi`
 2. Change into `abb-multi` and clone mozharness via:
 
         hg clone ssh://hg@bitbucket.org/adblockplus/mozharness -r adblockbrowser
 
 3. Symlink the adblockbrowser repo into `abb-multi`, e.g.:

 * If your `mozconfig` is not called `mozconfig`, change `MOZCONFIG`
 * **Remove the repository pulling part** from `config`.
   The code to remove looks like this:
 
         "repos": [{
             "repo": "https://hg.mozilla.org/%s" % REPO_PATH,
             "tag": "default",
             "dest": BUILD_DIR,
         }],
 
-* Change `"hg_l10n_tag"` in `config` from `default` to `FENNEC_44_0_2_RELEASE`
+* Change `"hg_l10n_tag"` in `config` from `default` to `FENNEC_45_0_2_RELEASE`
 * Add `en-ZA` to `ignore_locales` since it isn't currently supported
-* [Issue #3047][2] introduced a custom build step named `abb-transform-locales`
+* [Issue #3047][3] introduced a custom build step named `abb-transform-locales`
   for manipulating search engine availability and order. This must be inserted
   into `default_actions` right before `package-multi`
 * You might want to remove the `"backup-objdir"` build step if you do
   not want your objdir to be backed up. Keep in mind that you then need to
   clobber for a single-locale build.
 
 An example configuration could look like this:
 
     import os
     # The name of the directory we'll pull our source into.

 ### Building ###
 
 For performing the multilocale build, invoke
 
     ./mozharness/scripts/multil10n.py --cfg abb-multi-cfg.py
 
 from inside `abb-multi`. The resulting build is located in
 `BUILD_DIR/OBJ_DIR/dist/`
