+## Project LSP Setup
+
+This config uses a "lean core" approach where most LSPs come from your project's devShell via direnv.
+
+### How It Works
+
+1. **Core tools** (ripgrep, fd, lua-language-server, nil, etc.) are always available
+2. **direnv.vim** automatically loads your project's `.envrc` / `devShell` environment
+3. **Smart detection** warns you if an expected LSP is missing for a filetype
+
+### Example Project flake.nix
+
+```nix
+{
+  inputs.nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
+  
+  outputs = { nixpkgs, ... }:
+    let
+      pkgs = nixpkgs.legacyPackages.x86_64-linux;
+    in {
+      devShells.x86_64-linux.default = pkgs.mkShell {
+        packages = with pkgs; [
+          # Your project's LSPs
+          typescript-language-server
+          nodePackages.prettier
+          eslint_d
+          
+          # Your project's tools
+          nodejs_22
+          pnpm
+        ];
+      };
+    };
+}
+```
+
+Then create `.envrc`:
+```sh
+use flake
+```
+
+And run `direnv allow` in your project directory.
+
+## Local AI Autocomplete
+
+This config supports local AI-powered code completion via [llama.vim](https://github.com/ggml-org/llama.vim).
+
+### Setup
+
+1. Install llama.cpp:
+   ```sh
+   # macOS
+   brew install llama.cpp
+   
+   # Or build from source
+   git clone https://github.com/ggml-org/llama.cpp
+   cd llama.cpp && make
+   ```
+
+2. Download a FIM-capable model (e.g., sweep-next-edit-1.5B):
+   ```sh
+   # From HuggingFace
+   wget https://huggingface.co/sweepai/sweep-next-edit-1.5B-GGUF/resolve/main/sweep-next-edit-Q8_0.gguf
+   ```
+
+3. Start llama-server:
+   ```sh
+   llama-server -m sweep-next-edit-Q8_0.gguf --port 8012 --fim-qwen-7b-default
+   ```
+
+4. Neovim will auto-detect the server and enable completions
+
+### Usage
+
+- **Tab** - Accept completion
+- **Shift-Tab** - Accept first line only
+- **Ctrl-F** - Toggle FIM manually
+- **`<leader>,a`** - Toggle AI autocomplete on/off
+
+### Recommended Models by VRAM
+
+| VRAM | Recommended Model |
+|------|-------------------|
+| >64GB | qwen2.5-coder-32b |
+| >16GB | qwen2.5-coder-7b |
+| <16GB | qwen2.5-coder-3b |
+| <8GB | sweep-next-edit-1.5b |
+
+## Key Plugins
+
+| Category | Plugin | Description |
+|----------|--------|-------------|
+| Completion | blink.cmp | Fast async completion with LSP, snippets, buffer |
+| LSP | nvim-lspconfig | Native LSP configurations |
+| Diagnostics | trouble.nvim | Pretty diagnostics and quickfix lists |
+| Formatting | conform.nvim | Fast formatter integration |
+| Linting | nvim-lint | Async linter integration |
+| AI | llama.vim | Local LLM code completion |
+| Utilities | mini.nvim | Surround, comment, pairs, text objects |
+| Files | nvim-tree, telescope | File browsing and fuzzy finding |
+
+## Keybindings
+
+### LSP
+- `gd` - Go to definition
+- `gr` - Go to references
+- `gI` - Go to implementation
+- `K` - Hover documentation
+- `<leader>la` - Code action
+- `<leader>lr` - Rename
+
+### Diagnostics (Trouble)
+- `<leader>xx` - Toggle diagnostics
+- `<leader>xX` - Buffer diagnostics only
+- `<leader>xs` - Document symbols
+- `<leader>xq` - Quickfix list
+
+### Comments (mini.comment)
+- `gc{motion}` - Toggle comment
+- `gcc` - Toggle line comment
+- `<leader>/` - Toggle comment (preserved binding)
+
+### Surround (mini.surround)
+- `gsa{motion}{char}` - Add surrounding
+- `gsd{char}` - Delete surrounding
+- `gsr{old}{new}` - Replace surrounding
+
 ## NOTES/TODOS
 
-- See what linters/formaters to add or are the LSP's enough?
 - CSPELL/spelling linter
+- Consider mini-align for alignment
 
 FUTURE
 
 - Make a new HTTP plugin for running curl commands from .http files
-  - similar to est-nvim/rest.nvim but support streaming etc and show command output
-- Execute selected command and open output into a buffer/popup window? <leader>cx
+  - similar to rest-nvim/rest.nvim but support streaming etc and show command output
 - generate command, like scratch open a popup of things that can be generated. UUID/other stuff?

 - Checkout cargo-bloat, cargo-cache, cargo-outdated - memcache sccache
 - For scratches, just make an input box for custom extension rather than predefined list
-- freaking learn to use surround more often <https://github.com/tpope/vim-surround/tree/master>
-- make my own session saving impl
-  - Only save visible buffers/tabs/splits
-  - per branch per directory
-  - something like <https://github.com/gennaro-tedesco/nvim-possession/tree/main> but fully managed
-- copilot? local llm?
