+# Atferdskodeks for bidragsyterpaktern
+
+## Hva Vi Står For
+
+Vi som medlemer, bidragere, og ledere står for å skape ett hat-fritt felleskap,
+uansett alder, kroppstørrelse, synlig eller usynlige funksjonsnedsettninger,
+etnesitet, kjønns karaktertrekk, kjønnsidentitet, kunnskapsnivå, utdanning,
+sosial-økonomisk status, nasjonalitet, utsende, rase, religion, eller seksual
+identitet og orientasjon.
+
+Vi står for åpen, velkommende, mangfold, inklusiv og sunn oppførsel i vårt felleskap.
+
+## Våre Standarer
+
+Eksempler på oppførsel som hjelper ett positivt felleskap inkluderer:
+
+* Vise empati og vennlighet mot andre mennesker
+* Være respektfull ovenfor ulike meninger, synspunkter og erfaringer
+* Gi og ta konstruktiv kritikk i beste mening
+* Akseptere ansvar og unskylde seg for de som er utsatt av våre feil,
+  og lære av disse
+* Fokusere på det som er best ikke bare for individer, men for felleskapet
+
+Eksempler på uakseptabel oppførsel inkluderer:
+
+* Bruk av seksualisert språk eller bilder, og seksual oppmerksomhet.
+* Troll-ene, fornermende og nedsettende kommentarer, og personlig eller politiske angrep
+* Offentlig eller privat trakassering
+* Publisering av andres private informasjon, sånn som bosteds- og epost-addresser,
+  uten deres godskjenning.
+* Andre rettningslinjer som kan bli sett på som upassende i en profesjonell setting.
+
+## Håndhevingsansvar
+
+Felleskapets ledere har ansvar for å klarifisere og håndheve våre standarer av
+akseptert oppførsel og vill ta rimelige og rettferdige handliger som respons på
+oppførsel de anser som upassende, truende, fornermende eller skadelig.
+
+Felleskapets ledere har retten og ansvaret til å fjerne, redigere, eller avslå
+kommentarer, commits, kode, wiki endringer, issues, og andre birag som ikke
+samsvarer med disse etiske rettningslinjene, og vill kommunisere grunner for
+moderatorenes valg når passende.
+
+## Omfang
+
+Disse etiske rettningslinjene gjelder innenfor alle platformene til felleskapet, og
+de gjelder også når ett individ representerer felleskapet på offentlige medier.
+Eksempler på representasjon av vårt felleskap inkluderer bruke av offisielle e-mail
+addresser, publisering gjennom en offisiell sosial media bruker, eller oppførsel som en
+utpekt representant på digitale og fysiske arrangsjemanger.
+
+## Håndheving
+
+Hendelser av misbruk, trakasserende eller på noen måte uakseptert oppførsel kann
+bli raportert til felleskapets ledere med ansvar for håndheving på
+[info@rustdesk.com](mailto:info@rustdesk.com).
+All tilbakemelding vill bli sett gjennom og investigert rettferdig så fort som mulig.
+
+Alle felleskapets ledere er obligert til å respektere privatlivet og sikkerhetet ovenfor
+den som raporterer en hendelse.
+
+## Håndhevings Guide
+
+Felleskapets ledere vill følge disse Rettningslinjene for sammfunspåvirkning med
+tanke på konsekvenser for en handling de anser i brudd med disse etiske rettningslinjene:
+
+### 1. Korreksjon
+
+**Sammfunspåvirkning**: Bruk av upassende språk eller annen oppførsel ansett som
+uprofesjonelt eller uvelkommen i dette felleskapet.
+
+**Konsekvens**: En privat, skrevet advarsel fra en leder av felleskapet, som
+klarifiserer grunnlaget til hvorfor denne oppførselen var upassende. En offentlig
+unskyldning kan bli forespurt.
+
+### 2. Advarsel
+
+**Sammfunspåvirkning**: Ett brudd på en singulær hendelse eller en serie handlinger.
+
+**Konsekvens**: En advarsel med konsekvenser for kontinuerende oppførsel. Ingen
+interaksjon med individene involvert, inkluderer uoppfordret interaksjoner med
+de som håndhever disse etiske rettningslinjene, er tillat for en spesifisert tidsperiode.
+Dette inkluderer å unngå interaksjoner i felleskapets platformer, samt eksterne
+kanaler, som f.eks sosial media. Brudd av disse vilkårene kan føre til midlertidig
+eller permanent bannlysning.
+
+### 3. Midlertidig Bannlysning
+
+**Sammfunspåvirkning**: Ett særiøst brudd på felleskapets standarer, inkludert
+vedvarende upassende oppførsel.
+
+**Konsekvens**: En midlertidig bannlysning fra noen som helst interaksjon eller
+offentlig kommunikasjon med felleskapet for en spesifisert tidsperiode. Ingen
+interaksjon med individene involvert, inkluderer uoppfordret interaksjoner med
+de som håndhever disse etiske rettningslinjene, er tillat for denne perioden.
+Brudd på disse vilkårene kan føre til permanent bannlysning.
+
+### 4. Permanent Bannlysning
+
+**Sammfunspåvirkning**: Demonstasjon av mønster i brudd på felleskapets standarer,
+inklusivt vedvarende upassende oppførsel, trakassering av ett individ, eller
+aggresjon mot eller nedsettelse av grupper individer.
+
+**Konsekvens**: En permanent bannlysning fra alle offentlige interaksjoner i
+felleskapet
+

+#  RustDesk 기여 가이드라인
+
+RustDesk는 모든 사람의 기여를 환영합니다. 만약 RustDesk에 기여하고 싶다면 아래 가이드를 참고해주세요:
+
+## 기여 방식
+
+RustDesk 또는 종속성에 대한 기여는 GitHub Pull Request 형태로 이루어져야 합니다.
+모든 Pull Request는 코어 기여자가 검토하며, 메인 저장소에 반영되거나 필요한 수정 사항에 대한 피드백을 받습니다.
+모든 기여는 이 형식을 따라야 합니다.
+
+특정 이슈에 작업하고 싶다면, 먼저 GitHub 이슈에 댓글을 달아 작업하겠다고 알려주세요.
+이는 동일한 작업에 대해 중복 기여가 발생하는 것을 방지하기 위함입니다.
+
+## Pull Request Checklist
+
+- master 브랜치에서 새 브랜치를 생성하고 작업하세요.<br/>
+필요한 경우 PR 제출 전에 최신 master 브랜치에 리베이스(rebase)하세요.<br/>
+충돌이 발생하면 기여자가 직접 해결해야 합니다.
+
+- 커밋은 가능한 한 작고 독립적인 단위로 작성하세요.<br/>
+각 커밋은 독립적으로 빌드와 테스트를 통과해야 합니다.
+
+- 커밋에는 반드시 Developer Certificate of Origin (http://developercertificate.org) 서명이 포함되어야 합니다.<br/> 
+이는 기여자(및 소속된 고용주가 있을 경우) 가 [프로젝트 라이선스](../LICENCE) 에 동의함을 나타냅니다.<br/>
+Git에서는 `git commit` 명령어에 `-s` 옵션을 사용해 서명을 추가할 수 있습니다.
+
+- PR이 검토되지 않거나 특정 리뷰어가 필요하면, 
+<br/> PR이나 댓글에서 리뷰어를 태그하거나 [이메일](mailto:info@rustdesk.com)로 리뷰를 요청할 수 있습니다.
+
+- 수정된 버그나 추가된 기능과 관련된 테스트 코드를 포함해주세요.
+
+Git 사용에 대한 자세한 내용은 [GitHub workflow 101](https://github.com/servo/servo/wiki/GitHub-workflow)을 참조하세요.
+
+## 행동 강령

+# Bidrag til RustDesk
+
+RustDesk er åpene for bidrag fra alle. Her er reglene for de som har lyst til å
+hjelpe oss:
+
+## Bidrag
+
+Bidrag til RustDesk eller deres avhengigheter burde være i form av GitHub pull requests.
+Hver pull request vill bli sett igjennom av en kjerne bidrager (noen med autoritet til
+å godkjenne endringene) og enten bli sendt til main treet eller respondert med
+tilbakemelding på endringer som er nødvendig. Alle bidrag burde følge dette formate
+også de fra kjerne bidragere.
+
+Om du ønsker å jobbe på en issue må du huske å gjøre krav på den først. Dette
+kann gjøres ved å kommentere på den GitHub issue-en du ønsker å jobbe på.
+Dette er for å hindre duplikat innsats på samme problem.
+
+## Pull Request Sjekkliste
+
+- Lag en gren fra master grenen og, hvis det er nødvendig, rebase den til den nåværende
+  master grenen før du sender inn din pull request. Hvis ikke dette gjøres på rent
+  vis vill du bli spurt om å rebase dine endringer.
+
+- Commits burde være så små som mulig, samtidig som de må være korrekt uavhenging av hverandre
+  (hver commit burde kompilere og bestå tester).
+
+- Commits burde være akkopaniert med en Developer Certificate of Origin
+  (http://developercertificate.org), som indikerer att du (og din arbeidsgiver
+  i det tilfellet) godkjenner å bli knyttet til vilkårene av [prosjekt lisensen](../LICENCE).
+  Ved bruk av git er dette `-s` opsjonen til `git commit`.
+
+- Hvis dine endringer ikke blir sett eller hvis du trenger en spesefik person til
+  å se på dem kan du @-svare en med autoritet til å godkjenne dine endringer.
+  Dette kann gjøres i en pull request, en kommentar eller via epost på [email](mailto:info@rustdesk.com).
+
+- Legg til tester relevant til en fikset bug eller en ny tilgjengelighet.
+
+For spesefike git instruksjoner, se [GitHub workflow 101](https://github.com/servo/servo/wiki/GitHub-workflow).

+
+### Bygg
+
+```sh
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+source $HOME/.cargo/env
+git clone https://github.com/rustdesk/rustdesk
+cd rustdesk
+mkdir -p target/debug
+wget https://raw.githubusercontent.com/c-smile/sciter-sdk/master/bin.lnx/x64/libsciter-gtk.so
+mv libsciter-gtk.so target/debug
+VCPKG_ROOT=$HOME/vcpkg cargo run
+```
+
+## Hvordan bygge med Docker
+
+Start med å klone repositoret og bygg Docker konteineren:
+
+```sh
+git clone https://github.com/rustdesk/rustdesk
+cd rustdesk
+docker build -t "rustdesk-builder" .
+```
+
+Deretter, hver gang du trenger å bygge applikasjonen, kjør følgene kommando:
+
+```sh
+docker run --rm -it -v $PWD:/home/user/rustdesk -v rustdesk-git-cache:/home/user/.cargo/git -v rustdesk-registry-cache:/home/user/.cargo/registry -e PUID="$(id -u)" -e PGID="$(id -g)" rustdesk-builder
+```
+
+Det kan ta lengere tid før avhengighetene blir bufret første gang du bygger, senere bygg er raskere. Hvis du trenger å spesifisere forkjellige argumenter til bygge kommandoen, kan du gjøre det på slutten av kommandoen ved `<OPTIONAL-ARGS>` feltet. For eksempel, hvis du ville bygge en optimalisert release versjon, ville du kjørt kommandoen over fulgt `--release`. Den kjørbare filen vill være tilgjengelig i mål direktive på ditt system, og kan bli kjørt med:
+
+```sh
+target/debug/rustdesk
+```
+
+Eller, hvis du kjører ett release program:
+
+```sh
+target/release/rustdesk
+```
+
+Venligst pass på att du kjører disse kommandoene fra roten av RustDesk repositoret, eller kan det hende att applikasjon ikke finner de riktige ressursene. Pass også på att andre cargo subkommandoer som for eksempel `install` eller `run` ikke støttes med denne metoden da de vill installere eller kjøre programmet i konteineren istedet for verten.
