+#Installing a Ctags-lsp
+I got the impression, that there is a level of interest for installing some
+autocompletion in neovim. So this is a guide centering on implementing a ctags
+lsp provider inside of neovim.
+
+I use following config for lazy nvim:
+For installation config see [lazy.md](lazy.md).
+```lua
+return {"neovim/nvim-lspconfig",
+        dependencies = "netmute/ctags-lsp.nvim",
+        config = function()
+            vim.lsp.config("ctags-lsp", {
+               filetypes = { "c,h,cc,cpp,hh,hpp" }, -- Or whatever language you want to use it for
+            })
+            vim.lsp.enable("ctags_lsp")
+        end,
+    };
+```
+
+The config function actually does not have to be called inside declaration block
+lets say. So if you have an old legacy vim configuration, which is not based on
+lua, then you could add "netmute/ctags-lsp.nvim" and "neovim/nvim-lspconfig"
+manually to your config. (For example if you use Vundle or Vim-plug.)
+
+You can then add the following lua block to your config.
+```sh
+# Lua block
+
+lua << EOF
+-- Lua code here
+vim.lsp.config("ctags-lsp", {
+   filetypes = { "c,h,cc,cpp,hh,hpp" }, -- Or whatever language you want to use it for
+})
+vim.lsp.enable("ctags_lsp")
+EOF
+```
+
+
+# Installing the lsp binary
+The lsp binary should be in your user path, but since it is manually installed
+you should not add it to your */usr/bin* path.
+If `$HOME/.local/bin` is not in your path, I recommend you to add it to *PATH*.
+You can install the binary by running:
+```sh
+go install github.com/netmute/ctags-lsp@latest"
+```
+or by downloading the binary from the github page (see releases) and storing it
+in `$HOME/.local/bin`.

+# Installing lazy
+Lazy is one of packet managers for neovim, which is implemented and configured
+in lua.
+This snippet installs lazy via git cloning it to stdpath data from the github
+reposity.
+The path data specifies the neovim directory inside the directory specified by
+variable *XDG_DATA_HOME*, which defaults to `$HOME/.local/share`.
+
+I.e the default directory is $HOME/.local/share/nvim.
+```lua
+local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
+-- lazy.nvim installieren (falls nicht vorhanden)
+if not (vim.uv or vim.loop).fs_stat(lazypath) then
+	local lazyrepo = "https://github.com/folke/lazy.nvim.git"
+	local out = vim.fn.system({ "git", "clone", "--filter=blob:none", "--branch=stable", lazyrepo, lazypath })
+	if vim.v.shell_error ~= 0 then
+		vim.api.nvim_echo({
+			{ "Failed to clone lazy.nvim:\n", "ErrorMsg" },
+			{ out, "WarningMsg" },
+			{ "\nPress any key to exit..." },
+		}, true, {})
+		vim.fn.getchar()
+		os.exit(1)
+	end
+end
+-- Add lazy.nvim directory to the path lua path.
+vim.opt.rtp:prepend(lazypath)
+```
+
+
+## Sourcing plugins
+When adding following line:
+```lua
+require("lazy").setup("plugins")
+```
+
+Lazy will source all lua files found in the source directory plugins.
+
+The neovim config folder is: `$XDG_CONFIG_HOME`/nvim/, where *XDG_CONFIG_HOME*
+defaults to `$HOME/.config/`.
+I.e. the resulting directory which should exist is:
+`$HOME/.config/nvim/lua/plugins`.
+
+For simplicity each file in the directory should contain only one plugin.
+
+## Adding plugins
+Adding plugins is simple. Usually there is a example on the github page.
+But with this approach you need to add a `return` in front of the object
+and store the the into a new file.
+For example:
+```lua
+return {
+        "NeogitOrg/neogit",
+        dependencies = {
+            "nvim-lua/plenary.nvim",         -- required
+            "sindrets/diffview.nvim",        -- optional - Diff integration
+
+            -- Only one of these is needed.
+            "nvim-telescope/telescope.nvim", -- optional
+            "ibhagwan/fzf-lua",              -- optional
+            "echasnovski/mini.pick",         -- optional
+        },
+    };
+```
+This will return the shown object.
