+# Compile optimized
+Compile packages written in various languages using custom compile flags, typically this would override some attribute in the provided package derivation. A set of defaults is provided, which can be overriden. Additional flags may be set using `additionalFlags` parameter.
+
+You can use the functions as follows:
+```
+compileOptimized.${language}
+```
+
+## Example
+```
+compileOptimized.Rust {
+    enableNativeOptimizations = false; # No native optimizations
+} pkgs.rustc
+```
+
+## C
+Overrides: `env.NIX_CFLAGS_COMPILE`
+
+`CNoLTO` is also provided for convinience, as many packages may fail to compile with LTO enabled.
+
+### Defaults
+```
+{
+  optimizationLevel ? "O3",
+  enableLTO ? true,
+  enableNativeOptimizations ? true,
+  additionalFlags ? []
+}
+```
+
+## Rust
+Overrides: `RUSTFLAGS`
+
+### Defaults
+```
+{
+  opt-level ? "3",
+  debug ? "none",
+  split-debuginfo ? "off",
+  strip ? "symbols",
+  debug-assertions ? false,
+  overflow-checks ? false,
+  lto ? "fat",
+  panic ? "abort",
+  codegen-units ? 1,
+  enableNativeOptimizations ? true,
+  enableNoPIC ? false,
+  additionalFlags ? []
+}
+```
+
+# VSCode extensions
+A set of VSCode extensions is available, typically this would contain extensions which are missing from nixpkgs.
+
+Extensions are built from [TOML file](./packages/vscode-extensions/extensions.toml), which describes the required attributes for building in `info` section and additional information in `meta` section.

 Stackpkgs is a collection of packages and overlays commonly used in my NixOS configurations, split into a separate repository for ease of reuse and sharing.
 
+The list of available packages is available [here](./PACKAGES.md).
