+# deno_installer
+
+Install remote or local script as executables.
+
+## Installation
+
+`installer` can be installed using itself:
+
+```sh
+deno -A https://deno.land/std/installer/mod.ts deno_installer https://deno.land/std/installer/mod.ts -A
+```
+
+## Usage
+
+Install script
+
+```sh
+# remote script
+$ deno_installer file_server https://deno.land/std/http/file_server.ts --allow-net --allow-read
+> [1/1] Compiling https://deno.land/std/http/file_server.ts
+>
+> ✅ Successfully installed file_server.
+> ~/.deno/bin/file_server
+
+# local script
+$ deno_installer file_server ./deno_std/http/file_server.ts --allow-net --allow-read
+> [1/1] Compiling file:///dev/deno_std/http/file_server.ts
+>
+> ✅ Successfully installed file_server.
+> ~/.deno/bin/file_server
+```
+
+Run installed script:
+
+```sh
+$ file_server
+HTTP server listening on http://0.0.0.0:4500/
+```
+
+## Custom installation directory
+
+By default installer uses `~/.deno/bin` to store installed scripts so make sure
+it's in your `$PATH`.
+
+```
+echo 'export PATH="$HOME/.deno/bin:$PATH"' >> ~/.bashrc # change this to your shell
+```
+
+If you prefer to change installation directory use `-d` or `--dir` flag.
+
+```
+$ deno_installer --dir /usr/local/bin file_server ./deno_std/http/file_server.ts --allow-net --allow-read
+> [1/1] Compiling file:///dev/deno_std/http/file_server.ts
+>
+> ✅ Successfully installed file_server.
+> /usr/local/bin/file_server
+```
+
+## Update installed script
+
+```sh
+$ deno_installer file_server https://deno.land/std/http/file_server.ts --allow-net --allow-read
+> ⚠️  file_server is already installed, do you want to overwrite it? [yN]
+> y
+>
+> [1/1] Compiling file:///dev/deno_std/http/file_server.ts
+>
+> ✅ Successfully installed file_server.
+```
