-The goal of the project is to illustrate how to use a custom arm-none-eabi embedded toolchain with Bazel.
+The goal of the project is to make arm cross compilation toolchains readily
+available (and customizable) for bazel developers.
 
 If this project was useful to you, give it a ⭐️ and I'll keep improving it!
 
-You can follow the post [Bazel for ARM embedded toolchains](https://asnaghi.me/post/embedded-bazel/) to get more details about this code.
+You might also like another, similar, toolchain project for `bazel`
