 ### Dependencies 🧩

-already installed. You should probably follow their [installation
-directions](https://ta-lib.org/install/) for your platform, but some
-suggestions are included below for reference.
+Binary wheels include the [TA-Lib](http://ta-lib.org) C library and do not
+require a compiler or a separate TA-Lib C installation.
+
+Starting with version 0.8.3, source builds download the pinned TA-Lib C 0.8.1
+release, verify its checksum, and build and statically link it into the Python
+extension. This requires network access, a C compiler and CMake. On Windows,
+source builds require the Microsoft C++ Build Tools. CMake is installed
+automatically when using pip's default build isolation.
+
+To use an existing TA-Lib C installation instead, set ``TA_INCLUDE_PATH`` or
+``TA_LIBRARY_PATH`` before building. Setting either variable disables the
+bundled C build, including its download; if only one is set, the other uses
+the standard search paths. These variables accept multiple directories
+separated by ``os.pathsep`` (``:`` on Unix, ``;`` on Windows). They apply to
+source builds, not prebuilt wheels.
