## What is it?
@ -20,117 +20,77 @@ Glow is a terminal based markdown reader designed from the ground up to bring
out the beauty—and power—of the CLI.
Use it to discover markdown files, read documentation directly on the command
line. Glow will find local markdown files in subdirectories or a local
line and stash markdown files to your own private collection so you can read
them anywhere. Glow will find local markdown files in subdirectories or a local
Git repository.
By the way, all data stashed is encrypted end-to-end: only you can decrypt it.
More on that below.
## Installation
### Package Manager
Use your fave package manager:
```bash
# macOS or Linux
brew install glow
```
```bash
# macOS (with MacPorts)
sudo port install glow
```
```bash
# Arch Linux (btw)
pacman -S glow
```
yay -S glow
```bash
# Void Linux
xbps-install -S glow
```
```bash
# Nix shell
nix-shell -p glow --command glow
```
# Nix
nix-env -iA nixpkgs.glow
```bash
# FreeBSD
pkg install glow
```
```bash
# Solus
eopkg install glow
```
Or download a binary from the [releases][releases] page. MacOS, Linux, FreeBSD
binaries are available, as well as Debian and RPM packages. ARM builds are also
available for Linux and FreeBSD.
Or just use `go get`:
```bash
# Windows (with Chocolatey, Scoop, or Winget)
choco install glow
scoop install glow
winget install charmbracelet.glow
```
```bash
# Android (with termux)
pkg install glow
```
```bash
# Ubuntu (Snapcraft)
sudo snap install glow
```
```bash
# Debian/Ubuntu
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://repo.charm.sh/apt/gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/charm.gpg
echo "deb [signed-by=/etc/apt/keyrings/charm.gpg] https://repo.charm.sh/apt/ * *" | sudo tee /etc/apt/sources.list.d/charm.list
sudo apt update && sudo apt install glow
```
```bash
# Fedora/RHEL
echo '[charm]
name=Charm
baseurl=https://repo.charm.sh/yum/
enabled=1
gpgcheck=1
gpgkey=https://repo.charm.sh/yum/gpg.key' | sudo tee /etc/yum.repos.d/charm.repo
sudo yum install glow
```
Or download a binary from the [releases][releases] page. MacOS, Linux, Windows,
FreeBSD and OpenBSD binaries are available, as well as Debian, RPM, and Alpine
packages. ARM builds are also available for macOS, Linux, FreeBSD and OpenBSD.
### Go
Or just install it with `go`:
```bash
go install github.com/charmbracelet/glow/v2@latest
```
### Build (requires Go 1.21+)
```bash
git clone https://github.com/charmbracelet/glow.git
cd glow
go build
go get github.com/charmbracelet/glow
```

### Stashing
Glow works with the Charm Cloud to allow you to store any markdown files in
your own private collection. You can stash a local document from the Glow TUI by
pressing `s`.
You can also stash from the CLI:
```bash
glow stash README.md
```
Then, when you run `glow` without arguments will you can browse through your
stashed documents. This is a great way to keep track of things that you need to
reference often.
Stashing is private, its contents will not be exposed publicly, and it's
encrypted end-to-end. More on encryption below.

to find more styles. Or [make your own](https://github.com/charmbracelet/glamour/tree/master/styles)!
## The Config File
## 🔒 Encryption: How It Works
If you find yourself supplying the same flags to `glow` all the time, it's
probably a good idea to create a config file. Run `glow config`, which will open
it in your favorite $EDITOR. Alternatively you can manually put a file named
`glow.yml` in the default config path of you platform. If you're not sure where
that is, please refer to `glow --help`.
Encryption works by issuing symmetric keys (basically a generated password) and
encrypting it with the local SSH public key generated by the open-source
[charm][charmlib] library. That encrypted key is then sent up to our server.
We cant read it since we dont have your private key. When you want to decrypt
something or view your stash, that key is downloaded from our server and
decrypted locally using the SSH private key. When you link accounts, the
symmetric key is encrypted for each new public key. This happens on your
machine and not our server, so we never see any unencrypted data.
Here's an example config:
```yaml
# style name or JSON path (default "auto")
style: "light"
# mouse wheel support (TUI-mode only)
mouse: true
# use pager to display markdown
pager: true
# at which column should we word wrap?
width: 80
# show all files, including hidden and ignored.
all: false
# show line numbers (TUI-mode only)
showLineNumbers: false
# preserve newlines in the output
preserveNewLines: false
```
