+#### Building of libadblockplus
+
+First, we need to build `V8` required for `libadblockplus`.
+See `libadblockplus/README` or V8 documentation on how to build V8 or
+fetch precompiled one. For the latter, run in 'libadblockplus' directory:

+    make TARGET_OS=android ABP_TARGET_ARCH=ia32 Configuration=release get-prebuilt-v8

+Then we can build `libadblockplus`:

+    make TARGET_OS=android ABP_TARGET_ARCH=ia32 Configuration=release
