+# Development environment advice
+
+This documentation contain advice for setting up the development environment.
+
+Cuprate is a rust project, and therefore inherit the use of the default of LSP plugin Rust-analyzer. Rust-analyzer is well conceived but can be 
+slow on big project such as Cuprate. 
+
+Here are following suggested configurations from Polkadot-SDK's documentation:
+
+### Rust-analyzer's VSCode plugin:
+
+```json
+{
+  // Use a separate target dir for Rust Analyzer. Helpful if you want to use Rust
+  // Analyzer and cargo on the command line at the same time.
+  "rust-analyzer.rust.analyzerTargetDir": "target/vscode-rust-analyzer",
+  // Improve stability
+  "rust-analyzer.server.extraEnv": {
+    "CHALK_OVERFLOW_DEPTH": "100000000",
+    "CHALK_SOLVER_MAX_SIZE": "10000000"
+  },
+  // Check feature-gated code
+  "rust-analyzer.cargo.features": "all",
+  "rust-analyzer.cargo.extraEnv": {
+    // Skip building WASM, there is never need for it here
+    "SKIP_WASM_BUILD": "1"
+  },
+  // Don't expand some problematic proc_macros
+  "rust-analyzer.procMacro.ignored": {
+    "async-trait": ["async_trait"],
+    "napi-derive": ["napi"],
+    "async-recursion": ["async_recursion"],
+    "async-std": ["async_std"]
+  },
+}
+```
+
+### Rust-analyzer's Neovim LUA plugin:
+
+```lua
+["rust-analyzer"] = {
+  rust = {
+    # Use a separate target dir for Rust Analyzer. Helpful if you want to use Rust
+    # Analyzer and cargo on the command line at the same time.
+    analyzerTargetDir = "target/nvim-rust-analyzer",
+  },
+  server = {
+    # Improve stability
+    extraEnv = {
+      ["CHALK_OVERFLOW_DEPTH"] = "100000000",
+      ["CHALK_SOLVER_MAX_SIZE"] = "100000000",
+    },
+  },
+  cargo = {
+    # Check feature-gated code
+    features = "all",
+    extraEnv = {
+      # Skip building WASM, there is never need for it here
+      ["SKIP_WASM_BUILD"] = "1",
+    },
+  },
+  procMacro = {
+    # Don't expand some problematic proc_macros
+    ignored = {
+      ["async-trait"] = { "async_trait" },
+      ["napi-derive"] = { "napi" },
+      ["async-recursion"] = { "async_recursion" },
+      ["async-std"] = { "async_std" },
+    },
+  },
+},
+```
+
+### Usage of cargo -p
+
+Prefer to use cargo -p <CRATE> while possible, as any cargo in workspace mode will check and build dependencies of every crates in the repository.
+
+On Rust-analyzer's VSCode plugin, you can add the following configuration if you're focused on one specific crate:
+
+```json
+"rust-analyzer.check.extraArgs": [
+	"-p <CRATE_NAME>"
+],
+```
+
+### Alternative IDE
+
+If you still deal with lags on VSCode or Neovim, you could try the following IDE:
+- RustRover: It have been reported to have excellent performance at managing huge workspace. It use its own fine-tuned plugins by jetbrains.
+- Zed: Rust-written IDE focused on performance. Still in beta and macOS only.
