If `gitea` can use three different types of database, the documentation should simply pick one and continue instructions from there.
|
||||
Repetition works better than a reference - if a database requires three commands to set up, it's better to repeat those three commands for every program that requires a database than to just link to another file which discusses databases.

### Closing

Introductory documents should show anything required to cleanly uninstall a program, without leaving bulky configuration files behind.

## Three Input Types
|
||||
|
||||
There are three types of examples:
|
||||
|
||||
Fixed input:
|
||||
|
||||
```bash
|
||||
ls
|
||||
> ls
|
||||
|
||||
Arbitrary Input shows the non-fixed input in italics:
|
||||
|
||||
> ls *myFile.txt*
|
||||
|
||||
Output shows as unformatted text:
|
||||
|
||||
```
|
||||
|
||||
Anything with arbitrary input should be shown as a variable.
|
||||
|
||||
```bash
|
||||
ls $FILE
|
||||
LK img
|
||||
Mail kn
|
||||
Projects music
|
||||
```
|
||||
|
||||
Non-commands (e.g. output) should be shown as quoted text:
|
||||
|
||||
> LK img
|
||||
> Mail kn
|
||||
> Projects music

# Jenkins on Void
|
||||
|
||||
Jenkins is janky.
|
||||
|
||||
## Start
|
||||
Start the service file.
|
||||
|
||||
```bash
|
||||
sudo ln -s /etc/sv/jenkins /var/service
|
||||
sudo sv start jenkins
|
||||
```
|
||||
|
||||
Then visit the web interface with `$BROWSER localhost:8080`.
|
||||
|
||||
If it's not working, try running the command from the run file the first time:
|
||||
|
||||
```bash
|
||||
chpst -u jenkins java -jar /opt/jenkins/jenkins.war
|
||||
```
|
||||
|
||||
## Updating
|
||||
|
||||
Jenkins will not work if out of date.
|
||||
You will be prompted to update by downloading a `jenkins.war` file.
|
||||
Download it, then stop the service, and move the file to `/opt/jenkins/jenkins.war`, then start the service again.

host $domain.$tld

|
||||
> dmz.rs mail is handled by 10 kralizec.dmz.rs.
|
||||
> dmz.rs mail is handled by 20 splint.rs.
|
||||
|
||||
This shows the MX record has a secondary handler, called splint.rs.
|
||||
|
||||
You can also add a specific nameserver:
|
||||
|
||||
Request a specific record type (`CNAME`, `TXT`, et c.):
|
||||
|
||||
```bash
|
||||
torsocks host -T -t $RECORD_TYPE $domain
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
The `host` command uses UDP.
|
||||
You can change to TCP by using `host -T`.

|

## Change Default Location
|
||||
|
||||
The `transmission` user has a home configuration file, like any other user, with all the transmission settings.
|
||||
|
||||
```bash
|
||||
cd /var/lib/transmission/.config/transmission-daemon/
|
||||
|
||||
$EDITOR settings.json
|

```
|
||||
|

Change the `download-dir` value to wherever you want the torrents to go.
|
||||
|
||||
# Creating Torrents
|
||||
|
||||
Transmission always needs the full path to every file, and the daemon will need permission to view the file.
|
||||
When it doubt, just place the files in `transmission`'s home directory.
|
||||
|
||||
Create a torrent of file or directory `Memes` with:
|
||||
|
||||
```bash
|
||||
sudo chown -R :transmission Memes
|
||||
transmission-create $(pwd)/Memes
|
||||
```
|
||||
|
||||
Add a tracker to the torrent, to make sure others can find you easily:
|
||||
|
||||
```bash
|
||||
transmission-create --comment 'My Memes collection' -t 'udp://tracker.publicbt.com:80' -t 'udp://tracker.openbittorrent.com:80' --anonymize Memes
|
||||
```
|
||||
|
||||
Without the `--anonymize` flag, the torrent file output will have a 'created by' and 'created date'.
