-## Vendoring
-
-The default build process is to build using the vendored libsecp256k1 sources in
-the depend folder. These sources are prefixed with a special
-rust-secp256k1-sys-specific prefix `rustsecp256k1_v1_2_3_`.
-
-This prefix ensures that no symbol collision can happen:
-- when a Rust project has two different versions of rust-secp256k1 in its
-  depepdency tree, or
-- when rust-secp256k1 is used for building a static library in a context where
-  existing libsecp256k1 symbols are already linked.
-
-To update the vendored sources, use the `vendor-libsecp.sh` script:
-
-```
-$ ./vendor-libsecp.sh depend <version-code> <rev>
-```
-
-- Where `<version-code>` is the secp256k1-sys version number underscored: `0_1_2`.
-- Where `<rev>` is the git revision of libsecp256k1 to checkout.
