About us

BST Docs is a free learning library for programming and software engineering.

Courses are built as a progression, not a pile of articles: each one is divided into sections, each lesson builds on the one before it, and every lesson closes with a practical task so the material sticks.

Everything is free to read without an account. The library grows continually, and we welcome corrections and suggestions from readers.
